Best MPG You've Gotten

[Silverado12]

2012 Silverado-22 mpg
2007 Harley Dyna 96 c.i.-55 mpg
2002 Cavalier-40 mpg
1999 Jeep Cherokee-22 mpg

These mpg's are all when I'm actually trying to save gas and driving in the slow lane keeping up with the general flow of the slower traffic on the highway.

On a trip from NY to VA my 00 Century got between 36 and 37 mpg over 6 tanks of gas. That was last winter and I haven't tracked mpg in any of our vehicles since. The gas gauge in the Buick didn't work so we filled it every 300-350 miles. Calculating mpg gave my wife something to do.

On all highway runs I'll get around 40 per tank on my Cruze Eco with a manual. My best tank was 40.8, which was at 65 to 75 the entire trip. My lifetime mileage on the car is 33 combined. Not bad running cheap 87 with ethanol.

There are hyper-miling nerds who own this car and post significantly higher numbers than me. However, many of them seem to be running 91 or 93, so they may be spending more per mile, negating the benefit of their higher numbers. I've experimented and so far the extra mileage with higher octane fuel for me has not outweighed the extra cost of the fuel.

For an affordable commuter it's been a pretty good car so far.

2014 VW Jetta (1.8T)
41.6 mpg on a 21 mile drive to work.

If I don't feather the gas pedal I get around 35-38mpg

If I hammer the gas I still get around 30

Best tank I've seen is 44.2 on the '05 xB in my sig, running on the high plains of New Mexico. Around where I live, the best tank I've seen is 42.3 in the same car.

My wife's 2005 Legacy GT 5mt wagon has been 25MPG.

My Acura MDX on a trip to Quebec at 60MPH (<1800 RPM) 25MPG.

 

[IndyIan]

My best for a full tank in my cars has been 40mpg in my 95 3spd Neon.
The Focus wagon has been a bit of a mpg disappointment, 36 is the best so far, I do some coasting in N, but ignore the shift for mpg light and run it through the gears to 5k fairly often.
The old Tracker got a few 30-31 mpg tanks.
The CRV's best is 26mpg so far, and gets near that in daily usage.

Best on my 03 Cavalier (4-speed auto) was on a 300 mile stretch averaging around 75 mph: 40.1 mpg (around 90,000 miles ago).
Only time over 40 in it... not too much of an outlier since I've recorded over 39 on two other stretches and 37-38 a number of times.
Best on Mazda B2300 (5-speed manual) was just under 29 mpg with mostly highway driving.
Most I've ever recorded in anything was in my brother's 96 Saturn SL2 on a 245 mile stretch: 40.9 mpg.

1995 saturn Sw1 driven in June, 70 degree air, window cracked 2 inches, AC off, cruise at 58 mph, got 46.1 MPG.

 

[WobblyElvis]

2006 Malibu 2.2 litre.
On highway only, not touching the brakes once. 43 mpg US. at 60 mph.

When the Focus was still riding on the OE Hankook LRR tires, I could get 48-50 MPG round trip to my parents and back. Every trip was high 40s. I'd take a route that was mostly flat and I could speed up and coast between 45 and 55. Then the part closest to their house was up hill (or down, coming back).

Not so much with the Lifeliner GLS tires that replaced the Hankook. Eventually, when the lifeliner get low, I will replace them with something a bit more eco friendly. Probably a (cringe) LRR touring tire.

The Taurus had a few 34 MPG tanks. That was surprising!

2003 Jetta TDI 5 Speed: 53mpg highway. Only achieved this once. Haven't driven on interstate exclusively for several months

 

[supton]

My old 2004 VW TDi got 53 one winter. Was like 853 miles on the tank too.

I've never driven my wifes camry for mpg, so she likes to point out that I never get above 27-28 in it (and 23 once--but I think that was the pump not me). I think she has seen 36 in it. Her old 2001 Civic could hit 40, as could my 2000 Saturn.

Have done 22 in my Tundra.

2015 Ford C-Max: 46 MPG
2016 Ford Focus Electric: Infinity

 

[Blinker]

I got 42mpg avg on a tank of gas in my Pontiac G5 one time on a roadtrip. To be fair, Ohio had non stop 55mph road contruction so that made a big difference I'm sure.

The best mileage for my 2003 Honda Civic Hybrid was 60.5 mpg. Obviously it was all highway at 80 kph (50 mph).

Mild hybrids like the 03 Civic Hybrid do well on highway trips. I noticed my CMax hybrid gets only about 35 MPG if blasting across highways at 75 mph. In the city or suburban driving, it gets in the 40s MPG. All just the opposite of non-hybrids or mild hybrids. See how the city/highway numbers reverse:

I had a 1989 Honda CRX HF that consistantly returned mid 40's and I made a trip from Fort Hood to Elpaso one time in the car and got 51 mpg. But it was painfully slow..and absolutely reliable.

I was able to crack 60MPG in my 2006 Jetta TDI DSG (which normally returned 40-42MPG at 80 mph) . However, to do so required hypermiling. I drove the Florida back roads at a max of 45MPH, with the AC off. I shut the engine off 0.6-0.7 miles from each stop sign and rolled to a stop. I manually upshifted the DSG transmission and accelerated just quickly enough to get into 6th gear fairly rapidly. (in other words, slow accel)

Thank goodness there were few cars on the road while I was doing this. I waved a few people around me.

So, that tank of fuel exceeded 62MPG. But the additional number of hours I spent on the road were uneconomical (as it nearly doubled the time I spent per mile) . My time is worth more than 50 cents per hour! In other words, the savings are simply not worth it.

Lots of people were doing this in the summer of 2008 when gas prices were near $5/gallon. Is that when you were trying that? Far fewer care at $2/gallon.
