Mile per gallon / klick per liter claims

[DyerWolf]

Some of the recent OTB discussions got me to wondering about some of the MPG / KPL claims folks are making regarding automotive fuel efficiency.

So here's the experiment (if you're willing to help out):

Please start with a full tank of gas. Zero out your trip odometer and drive until the tank is almost empty before refilling. Then work out your actual miles per gallon or kilometers per liter per tank of gas.


When you post, please describe your vehicle, its engine, the fuel used and your driving type.

Thanks!

Here's my info:

Vehicle: 1997 GMC Yukon
Engine: 5+liter V-8
Fuel: 87 Octane Gasoline
Driving: Mixed Commuting / Highway
AVG MPG: 14 MPG


This is a real world experience test - one thing I want to avoid is manufacturer's claims.

TIA

This is a real world experience test - one thing I want to avoid is manufacturer's claims.
In keeping with the spirit of how I read your intentions (whether right or not), maybe the claim could be a good piece of information to include as a comparison.

I drive a 2001 Honda CR/V with over 72,000 miles on it. In day to day driving (virtually all in town), it averages from 26-28 MPG. My mileage has dropped lately but there are perhaps some factors (new tires, cold weather, changing traffic patterns, oxygenated fuels in the Winter) that may explain the drop.

[jseefcoot]

1999 Honda Accord 2-door
110,xxx miles
4-cyl VTECH @ c. 2 liters
87 Octane (brand names only, no cheap gas)
40% city/60% highway
26 mpg on daily driving

On extended trips where highway driving gets into the 80%-90% range the mpg can get over thirty, depending on how I drive the car.

[Tog_]

I have a 2005 Scion xB (stop laughing)
No idea on the engine size. 4 cyl and gutless
It looks like a shoe box with a hood and the odometer reads low.
I use 88 octane
It gets about 33 MPG and of the 400 miles a week I drive to and from work, 380 is highway at an average speed of 70-75.

I also tested the octane's effects. Since I fill up once every 4 days I thought the extra buck might be worth it in the long run. Mileage went down a bit to about 31 with 91 octane. I tried it with two tanks.

My other car was a 1995 Dodge Neon.
1.6 liter I think. 132 hp whatever size that was.
this was with 91 octane.
When it was new it got between 34.5 and 35.5 mph on the highway no matter what, except one trip where it got 44. To this day I have no idea why. In town it got about 26.

[Laguna]

Kilometers per Liter?
I have to make some calculations. Usually we give Liters per 100km.

Car#1
Renault Laguna I. Build 1997. 215000 km.
It has a 1.8l engine with 75 hp.

We have a 50% split between road and autobahn use, where the autobahn part is driven at fast speed, if possible (150km/h and faster).

In total it consumes about 7.2l/100km of unleaded fuel (95 octane), which would be about 13.9 km per Liter or 33 MPG.

Car#2:
Audi A4. Build 1997. 120000km
It has a 1.6l engine with 90hp.

Driving conditions are equal to the Renault, just that we can go faster :D

In total it consumes about 8.5l/100km of unleaded fuel (95 octane) or about 11.8km per Liter 28 MPG.


Oh, we are planning on buying a new car.
Renault Grand Scenic.
1.9l Commonrail Turbodiesel with 130hp.
5.0l/100km (47.5 MPG), says the vendor...

[Swift]

I have not done your experiment exactly your way Dyerwolf, but I have kept very careful track of my miles and gasoline since I purchased my car (I have a spreadsheet on my home computer for this purpose).

I have a 2005 Ford Escape Hybrid, Front Wheel Drive. The gas engine is, I believe, 2.2 liters, plus the electric. I am approaching 60,000 miles on the car. Most of my driving, probably around 75%, is highway. Over the entire course of my ownership, I am running 33.8 mpg. I always use 87 octane.

The biggest source of variation seems to be outside temperature. In the summer I average around 36 mpg, in the winter around 32. I have a graph showing my mileage on a monthly basis, as a function of average temperature, and it is close to linear.

I think there are two factors. Particularly with smaller gas engines, they are less efficient in cold weather. My former car, a Toyota RAV4, showed about a 10% drop in mileage in the winter. I also thing the amount of charge the battery can hold drops in colder weather (just like your starter battery on a regular car).

[Peter Wilson]

My other car was a 1995 Dodge Neon. When it was new it got between 34.5 and 35.5 mph on the highway no matter what...I knew Dodge Neons were slow, but that kind of speed on the interstate is hazardous :razz:

Mine? 2001 Honda Civic, 2-door, stick-shift, reg. gas. About 40 mpg, city/highway.

[Torsten]

I keep a book in my vehicle in which I record every fuel purchase and maintenance expense. I use 87 octane fuel. Like Swift, I keep a spreadsheet too.

So, for a 1999 Ford F150 extended cab, short box (normal wheel base) with 4.6 litre engine and automatic transmission, the fuel consumption averaged 16.0 l/100 km over a distance of 146,000 km. Most of that driving was highway and logging roads, but a good portion of it was packing a snowmobile or ATV in the back, and some of it involved going through deep unplowed snow. Perhaps 10-15% was short trips in town from a cold start. The best it did was 14.0 l/100km on a couple of long highway trips.

But that truck was written off after it was rolled on March 31 (a young driver at the wheel, who shall remain nameless) and I replaced it with a 2003 F150. Powertrain and body style are the same. In the first two tanks, most of which was highway driving, it has burned 13.8 l/100 km, or 17 miles/US gallon.

[Laguna]

Wow, 16l/100km. Can you already hear the whirlpool in your tank?

[Tog_]

I knew Dodge Neons were slow, but that kind of speed on the interstate is hazardous :razz:

I say to you : "Bah..."

Actualy it was pretty quick but the best it could do was 112. I learned two things that day. The GPS only goes to 99. The car starts to want to fly at 97.

The new car is automatic though and I really hate that. I miss shifting.

[SeanF]

I have not done your experiment exactly your way Dyerwolf, but I have kept very careful track of my miles and gasoline since I purchased my car (I have a spreadsheet on my home computer for this purpose).
Ah, a man after my own heart. :)

I have a 2001 Saturn SL2. I don't know the engine specs, I'll have to check on that. I bought the car in October of 2000, but I'm going to start from October 2001, because that's when I started a new job and began driving quite a bit more highway.

Since October 2001, I've driven 64640.7 miles and burned 2154.721 gallons, for an average MPG of almost exactly 30.

Mine also goes up during the summer and down during the winter, but I suspect that's mostly a result of the fact that I let the car "warm up" during the winter rather than just starting it up and going. :)

[Tog_]

As long as people are looking at this stuff. I've always found it interesting that everything my dad and I have owned in the last 10 years had has a 340 to 380 mile range. If it gets 30 mpg, or 10, the tank is sized to match. Anyone else have figures?

[Lianachan]

According the computer on the 2006 Ford S-MAX I use for work, it gives me about 44 miles per gallon from its 1.8 litre turbo diesel engine.

I have just replaced my own car, due to an engine dying last Friday, so cannot comment on the economy of the car I bought a few days ago (1997 Vauxhall (Opel) 2.0i 16v Vectra) to do me a couple of months until I get a proper car.

[Nicholas_Bostaph]

I've been doing this since I bought my car. :)

Vehicle: 2002 Pontiac Firehawk T/A

Driving: backroads to work (40-60 mph)

Driving: Interstates on last 937 mile trip (60-100+ mph)

[Torsten]

Wow, 16l/100km. Can you already hear the whirlpool in your tank?

Yes, unfortunately. (And I also realized I forgot to mention that it is 4 wheel drive, which is used often.) I really look forward to the day when I just own a little sedan that uses about 5 l/100km. But in the meantime, I frequently have to pack stuff, and travel roads that require 4WD.

Nevertheless, it's better than what I just completed this morning: 3.3 hours in a JetRanger @ 100 litres per hour, and I never got more than 80 km from the base.

[NEOWatcher]

Wow, 16l/100km. Can you already hear the whirlpool in your tank?
And is that clockwise or counter clockwise?
By the way, is that dependent on whether it is left or right hand drive? :think:

[swansont]

2000 Honda Prelude, 4 cyl 200 HP

I typically get 25-26 mpg in city/suburban driving, and ~ 30 mpg when I get on the highway.

[Swift]

As long as people are looking at this stuff. I've always found it interesting that everything my dad and I have owned in the last 10 years had has a 340 to 380 mile range. If it gets 30 mpg, or 10, the tank is sized to match. Anyone else have figures?
That is pretty close to my experience, at least for my last 2 cars.

[Laguna]

My range has always been above. Somewhere around 430 miles range and above.
But I do not drive cars with 4 liter engines... ;)

[Captain Kidd]

I do this every now and them, but rather than a single tank, I'll do it over 1000 to 3000 miles or so to get a good average. A single tank isn't that long really.

I've discovered that my Mitsubishi Galant gets relatively poor mileage at 24ish and the Chevy Lumina gets 28 or so.

I need to do it again now that I've switched from half city/half road to 90% road. Were I really of a mind to do some testing, I'd also try it at 75 mph on the interstate (my normal speed), and then at 65 to see what the different is. The Galant give signs that sustaining 75-80 mph (at roughly 3100 rpm) is right on the edge of it's current ability. (I got it used, it has 140k miles, and I'm thinking it might not be much longer for this world.) However, 65 mph might put me in danger ... heck at 80 (speed limit of 70 mph) I'm still passed more than I pass.

[Arneb]

I also do this every time I fill up. I had to drive 200 km per day on the autobahn during the last four months - I could see ion my gas bill how sensitive consumption is to speed.

I drive an Audi A6 2.0 l machine on unleded RON 95 fuel, 1997 build; odometer shows 160,000 km (100,000 mi).

Contrary to laguna2, I settled for a sedate 130-140 km/h (80-85 mph) on the autobahn. That allowed me to consistently hold the car down to the minimum consumption I had determined in the previous years: 9.0 l/100 km - 26 mpg.

As soon as I settled for a more laguna2-type speed behaviour (160 km/h - 100 mph) or more, the consumption went up by at least 10-15%.

By the way, with 200 km (124 mi) per day für 20 working days, at € 1,35/l ($ 6,90 per gallon), this worked out to a monthly gas bill of € 495,--, or $ 690... I resigned the job. Now will our American brethren stop whining (http://www.bautforum.com/showthread.php?t=57098) about fuel prices, please?

[Laguna]

Wel, when driving "sedate" speeds, I can get the consumption down to 6.8l-7.0l (Laguna I) and 7.9-8.2l (Audi A4). But as my way to work has four lanes, and as I get up early to avoid the morning traffic, I am always tempted to step on that pedal to the very right...

[cjl]

Well, our 2007 Subaru Outback (2.5L flat 4, 5 speed stick) gets about 26ish in combined driving if you are very gentle with it, or 23 or so when you step on it a bit more. Pure interstate driving is around 28.5...

[DOOMMaster]

Wow, I'm kinda surprised I'm not the only person who does this. I have to drive a lot for work (3000-4000 miles a month) and always see what my mileage is for my work car.

2007 Ford Focus ZXW (wagon)
2.0L 4 cylinder engine, 5 speed manual, front wheel drive
Average 30-34 MPG, dependent on whether I do more city driving than highway

I also carry about 200 pounds of parts in my car, as well as my 160 pound self. It's rated at 27/37 MPG, and seems to be pretty accurate at that.

My other vehicles are a 97 S-10 truck, 2.2L 4 cylinder, 5 speed manual, 2WD rear and 94 Camaro Z28, 5.7L 8 cylinder, 6 speed manual, RWD. I'm not sure the mileage on the S-10, the gas gauge is broken and I usually make sure to fill the tank every 350 miles so I don't run out.

The Camaro is currently getting infinity MPG. Course, that's because I'm replacing the engine right now. :-) When she ran, though, I was usually getting 20 in the city and about 30 on the highway. That 6 speed manual really helps out, but only if I decide to keep my foot out of it.

[Pinemarten]

I have an '88 Buick Park Avenue, loaded, with 4pd automatic with OD.
3.8V6 EFI, 250,000km but still tight, no turbo.

City is horrid, I only drive 2mi to work and the motor never reaches optimum temperature, but I get 1.1 month per tank = 65-75 litres.

Highway is 37mpg CDN / 1.25 conversion is 29.6mpg US at 160kph= 100mph cruising speed. Mileage is the same at speeds down to 50mph due to the OD.
I recommend OD for all that are communting long distances.
I used 128oz? US to 160oz CDN gallon = 1.25? Edit: US and Imp oz are different sizes should be approx 1.2.

[LurchGS]

heh. I feel... republican.

I drive a 1995 Lincoln Continental, 4.6L Transverse Engine (Custom Police model, pulled from a mildly destroyed Highway Patrol Corvette)

It's almost exactly 25 miles to work, one way. 23 of it is highway. It usually takes me 30 minutes to get from my driveway to the parking garage (or vice versa). 15 of that is highway, 15 is city.

On the highway at 75Mph, I get 25 or so (fluctuates a bit owing to weather). Lower MPG at 65 and 85

On city streets, stopping and sitting for a minute at a time (minimum) at stop lights, mileage is reduced.. no, that's not the word.. *Plummets* comes close - to about 13mpg. All in all, it averages to 20.5

(I cheat - I have one of those built in luxury dinguses that gives you MPG average, MPG "now", and distance to empty. The first year or so I owned it, kept careful records and compared to the figures the car was giving. Accurate to within my ability to measure. Good 'nuff.)

(I wish to point out that during our pre-xmas blizzard, I used that car to pull 4 SUVs from the drifts at the side of the interstate on my way home. Which, I think, goes to show that it's not the car but the driver. I did finally get stuck - I slipped off the tracks of whatever vehicle went down the street before me, and I high-centered. 50 feet from my driveway.)

The Blazer.. she's in bad shape. Needs some sensors, a few other things. Lucky to get 15Mpg downhill with a tailwind.

The Cougar... hrm.. it's been a while since we broke it - I seem to recall it getting about what the Lincoln gets, though. Just better city.

The RV is gone - but it got about 6 Mpg on the Interstate.

[NEOWatcher]

everything my dad and I have owned in the last 10 years had has a 340 to 380 mile range.
I've experienced around 300.

I currently have an 03 trailblazer.
17mpg +/- 1mpg for most driving conditions.
12mpg towing at 50 mph.
7mpg towing at 65 mph. (stupid air resistance)

Hopefully, when the payments end, I will be able to get a 2nd vehicle for daily driving that gets at least 50mpg.

I seem to remember that once upon a time the U.S Dept of Transportation mandated that every vehicle be able to travel 300 (350?) miles on a tank of gas, regardless of its efficiency. I don't know if that is still in effect, given the recent revamping of fuel efficiency standards. And while I can't find or remember the source, I think it's an old one -- something I learned back in high school maybe.

[Peter Wilson]

Kilometers per Liter?

...In total it consumes about 8.5l/100km of unleaded fuel (95 octane) or about 11.8km per Liter 28 MPG...


So to convert from MPG to l/100km you divide by 3.3?

[Torsten]

So to convert from MPG to l/100km you divide by 3.3?

No, the two measures are in a sense reciprocals of one another. One reports how far a vehicle travels on a unit of fuel, the other reports how much fuel is used to go a unit of distance, typically 100 km. Instead of multiplying or dividing the term we want to convert by a constant, we divide a constant by the term we're trying to convert.

So, to convert l/100 km to miles/US gallon, divide 235.2 by the l/100. And to go from mpg to l/100 km, divide 235.2 by the mpg.

For conversion to imperial gallon, use 282.5 as the constant.

[Pinemarten]

Was my estimate of 160oz/128oz = 1.25 the correct coversion for imperial to US gallon?

[Torsten]

Was my estimate of 160oz/128oz = 1.25 the correct coversion for imperial to US gallon?

Right idea, but the problem is that the fluid ounce is also different between these systems.

There are ~1.041 imperial oz in a US oz, so the conversion works out to 1.2009 US gal / imperial gal.

[Pinemarten]

I can see where I got confused Wiki has 160imp and 128US, but doesn't say the ounces are different. I does work out to about 1.2 when dividing with litre equivalents.
http://en.wikipedia.org/wiki/Gallon

Just found it:
http://en.wikipedia.org/wiki/Fluid_ounce

[Torsten]

And, actually, the fluid ounce in each system is defined as a fraction of the gallon, 1/160, and 1/128, and the gallon in each system is in turn defined differently.

So, my previous post makes it sound like the gallon in each system is defined in terms of different numbers of differenty sized fl oz, when really the difference in the size of the fl oz is a consequence of the difference in the size of the gallon and how the gallon is subdivided.

Hmmm, gone a bit of topic here. I guess that's what the babble board is about though.

Yes, my 27 year old V8 with 100K+ miles on it gets the same highway mileage as my 1 year old Toyota... of course the Toyota weighs about 1500lbs more then the Vette...

[Pinemarten]

It is an apples/oranges thing.
The gallons have two different amounts of two different sized ounces. I think going in and then out of metric is the best way to do the math.
US gal = aprox 3.76l / imp gal = 4.55l = .826 x 1/.826 (inverted) = 1.21.

I don't think it is off topic. We have many nations here trying to convert to many other nations for the purpose of comparison. I edited my previous post to save confusion.

Off topic: I have a few refineries down the road that sell 87 octane to the 'locals' for .20CDN per litre.

1981 Chevy Corvette 5.7ltr V8
2003 Toyota Tacoma Quad Cab Prerunner
2006 Toyota Tacoma Quad Cab Sport 4x4

Every one of them has had a range of about 300 miles per tank. I normally fill up around 240 miles but I can stretch it to 300 without worrying about running out...

[ToSeek]

56.1 mph lifetime (just over 50,000 miles) in our 2000 Honda Insight (hybrid). We can easily go 500 miles between fillups.

(On the other hand, my other car, a 1991 Nissan NX 2000, gets more like 25 mph in mostly city driving and doesn't get much over 200 miles per fillup.)

[Trebuchet]

I had to do a round trip from Everett, WA, to Tacoma, on to Port Townsend, and back today so I filled up before and after and checked the mileage. 280 miles, most all highway at 50-65 mph.

1988 Mazda B2200 pickup maintained pretty much not at all. 78K miles, usually driven just a couple miles to work.

I was very surprised to get 33.5 mpg for the trip. I expected somewhere between 20 and 25. Range looks to be pretty good, the needle was just below half so it should comfortably do 400 miles.

Next trip I'll try the '85 CRX. I've checked it (years ago) at over 40 mpg but it's got 130k miles now. It's always suffered from Tiny Tank Syndrome. It'll take about 9 gallons when the needle is well below the "E", limiting range to 300 miles or so.

[Delvo]

I found this thread after returning home from a fairly long trip. I went to the city my family lives in by train, picked up my father's car because he doesn't drive anymore, and brought it back with me (making some sightseeing stops along the way). That makes the question easy to answer because I have the receipts. Going from full tank to full tank, I travelled 1433 miles on 62.672 gallons, which is 22.86508 miles per gallon (and spent $180.04 on the fuel, so the miles per dollar was 7.959342).

That was in a 2001 Chrysler PT Cruiser with a 2.4L I-4 engine, and not the most efficient that that car can get because it was almost all on interstate highways at speeds higher than what they have in mind when they say highway mileage is higher (which is based on slower highways than the interstate highways, especially slower than interstate driving by a driver who's not used to a car that goes so fast so easily, smoothly, and quietly and thus tended to drift into higher speeds when not focussing on keeping it down!).

I maintain everything myself. No other person has put a wrench on this truck. It has an performance air induction system and drilled rotors, the only upgrades I have bothered to install.

I am consistent in my driving habits. You know the old story about the vehicle that 'passes you like a bat out of Hades?' Well, I'm the bat. :D

I average 18 mpg, and I am quite happy with that.

[Maksutov]

Some of the recent OTB discussions got me to wondering about some of the MPG / KPL claims folks are making regarding automotive fuel efficiency.

So here's the experiment (if you're willing to help out):

Please start with a full tank of gas. Zero out your trip odometer and drive until the tank is almost empty before refilling. Then work out your actual miles per gallon or kilometers per liter per tank of gas.No problem. Just send the money (cash) to the address I'll PM you. When you post, please describe your vehicle, its engine, the fuel used and your driving type.

Thanks!...1998 Nissan Altima SE with all the extras.

Easy going: got rid of the teen hotrodding instincts via my 1964 1/2 Mustang.

Although the money hasn't arrived yet, I'll describe my last tank-to-tank experience.

39 MPG highway. Set her on cruise control and get good mileage. One time, with the 15.9 gallon tank filled I made it to just under 600 miles before the warning light started flashing.

33-34 MPG around town. It pays not to have a foot made out of lead.

Plus I do all my own maintenance and have made a few "special" modifications which have perhaps enhanced the mileage. BTW, tire inflation is really important.

It's a few miles from 110,000 now. I know Nissans don't have the same resale value as Toyotas or Hondas, but that's not important to a penny-pinching New Englander. The last car I had (which I traded in on the Altima) was a 1988 Olds Cutlass Calais. When traded it had 263,000 miles on it.

I hear if you don't use the cigaret lighter, you can get up to 22.86509 miles per gallon ;)

56.1 mph lifetime (just over 50,000 miles) in our 2000 Honda Insight (hybrid)...


Is it true that hybrids actually get better mileage around town than on the freeway?

I've even heard claims of 22.86519 if you remove the conspiratorial gas hogging device put in by the oil cartels...:shhh:

Or was I not supposed to say that?:think:

Depends on the hybrid - the Toyotas generally work that way, but our Honda does much better on the highway. I can get 70 mphg and sometimes more if I can maintain a steady speed on a level road. City driving is closer to 50 mpg.

Mods get odd when prodded about sodded bodkins.

Reminds me of one of my favorite cautionary statements:

"Proper prior plumbing prevents poor performing ****ers..."











:think: or was it, "Proper prior planning prevents ****-poor performance."??? - gotta love military aphorisms!

This is fun. What other forum would have people giving gas mileage to the ten-thousandth of a mile? Too funny.

2001 Mitsubishi Gallant GSX
V-6
140,000 miles
Mostly highway (75 miles daily round trip for work)
87 octane from wherever it's cheapest
I'm a leadfoot and cruise at 80 whenever possible
20.000000000001 MPG with the closest thing to an alternative rock station cranked up high, 19.99 repetend 9 with the local right wing talk radio guy turned down to a whisper

The manual says to use premium. I never have because of the ridiculous price. It never diesels and seems to run fine. Maybe I'll try it and see if the gas mileage increse is worth the price.

Too funny.I'm used to people thinking that even stating the frequency with which both the 13-year cicada and the 17-year cicada are out in the same summer (once in 221 years), in WHOLE YEARS instead of calling it something else "rounder" like 200 or 225, is excessive. :wall: :doh: :(

So, was one of those in the early to mid-70's? I remember a year right around then when they were incredible in numbers. (Lived in Illinois at the time). When is the next cicadic harmonic concordance?

I've never noticed it make a difference. - 'Course I never broke it down to the ten-thousandth of a mile either - you may see some change at that resolution that is imperceptible via the rough calc I've always used...

City driving is closer to 50 mpg.The reason I asked is because here in Kalifornia, they allow hybrids with one driver in the commuter lanes.

This "sort-of" makes sense if you apply the same logic that allows motorcyles in commutre lanes (M/Cs get such good gas mileage they are "as good as" car-pooling). But it doesn't make sense from the global-warming perspective if the hybrids are actually getting worse gas mileage by going faster :p

Seeing as my concern only applies to Toyotas, I guess you could say the law is half-baked...as opposed to all-bad :wall:

Try googling Cicadian rhythm :rolleyes:

[Delvo]

Cicadas of the same species aren't necessarily synchronized in different parts of the continent. In one place I've been, one species was out in 2005, and another place got both in 1998, which is only a 7-year difference, so the two places had to be on different schedules for at least one species.

Oh, we are planning on buying a new car.
Renault Grand Scenic.
1.9l Commonrail Turbodiesel with 130hp.
5.0l/100km (47.5 MPG), says the vendor...

Plans are plans ...

Our new car:
Mazda 5 MZR-CD 2.0 146 hp.
6.3l diesel per 100km.

Meanwhile I did a retest of my Altima's MPG.

Highway was 43.14159265358979323846264338327950288419716939937 51058209749445923078164062862089986280348253421170 67982148086513282306647093844609550582231725359408 12848111745028410270193852110555964462294895493038 19644288109756659334461284756482337867831652712019 09145648566923460348610454326648213393607260249141 273 MPG, whereas around town I got 32.71828182845904523536028747135266249775724709369 99595749669676277240766303535475957138217852516642 74274663919320030599218174 MPG.
