What's the best MPG you've ever managed?

[Scouzer]

Today I got my new record... quite handily in fact.

I slowed down from the 68mph speed limit down to 61mph and managed 42mpg over about 150 miles. 90% Highway.

I normally average 36mpg for this trip at the speed limit, pretty good!

Car: Pontiac G5 Pursuit GT 2.4L

What about yours?

 

[DivideBYZero]

8mpg.

 

[microAmp]

18.3 MPG

 

[Throckmorton]

19.5

 

[Aikouka]

27 in my Altima 3.5SL.

Unfortunately, it seems most of the ways to increase my mileage depend on other drivers not sucking like they usually do.

 

[Toastedlightly]

28 mpg in my thunderbird

 

[JulesMaximus]

Best I saw was 60mpg out of a tank of gas with my Suzuki SV650. Usually I average about 48mpg with mostly city riding.

First off my car is far from typical ...

100 mpg over 75 miles, average speed 45 - 55 mph, this spring.
Current tanks are 81mpg, or 850 miles per 10.5 gallon tank, this lasts about 4 weeks. Add on to that about $3.00 - $4.00 in electricity a month.

I'm not done counting yet...couple thousands of miles on my bike and still haven't used a gallon.

Bicycle .... infinite mpg, unless you count water, Gatorade, etc.

I got 28 mpg a few weeks ago

2008 CRV EX AWD

 

[Riverhound777]

Averaged 35mpg over 300 miles in my Mazda 3s. Had a nice tailwind. Usually I get 32mpg max.

I think the Insight has the win here (for motorized vehicles), unless someone shows up with a Honda NX125 and a light throttle.

Personally, my old 89 Civic got me ~40 or so, with mild driving technique, no A/C usage, and mixed driving. Those were still the days of small/light cars

 

[vi edit]

Last tank in my Mazda5 got me 370 miles from 11 gallons.
A little over 33MPG.

Not too bad. That's probably about the best I've got in a vehicle.

I'm currently squeezing out 17mpg city in my 5.3L Silverado. That's with bad tires too. I've gotten as high as 25 on the highway before going at about 55 with a tonneau cover.

Yesterday I averaged 57.8 MPG in my 240 HP Accord over 29 miles at ~55 MPH. Downhill, of course.

But the trip uphill over the same route was 25.1 MPG, giving me an average of 41.95 MPG round-trip.

That figure was verified by my GPS and pump calibrated ScanGauge II. That's my best round-trip score since getting the gauge. It's also a great example of how engine efficiency increases with wider throttle openings. I used the mountain as a "momentum battery," ran the engine harder filling up my "battery," then cashed in the momentum downhill, where the engine used automatic fuel cutoff to coast a lot of the way back down using no gas. The result was less gas burned than if I had simply driven the same speed at constant throttle over level ground.

I've found that with a careful right foot, I can average ~35 MPG over long distances, including up and down mountain ranges.

33.x all highway when I first bought my 2000 WS6. Six speed FTW.

 

[overst33r]

34.57 mpg on my last tank. That's without A/C and 70hwy/30city.

My current tank will be with A/C on the same route. Just trying to see how much the A/C affects my mileage.
