Default Most distance on one tank of gas?

I got 690km (428 miles) on one tank of gas, the fuel light came on at 650km. It took 61.5 L to fill it up. I'm pretty happy with that, and I wasn't babying it until the last 1/4 tank either. There were a few tire spinning launches and alot of driving with the sunroof open and the windows down. It was about 70/30 hwy driving. L8r...Andru.

I'v gotton about the same (little over 400 miles). I was doing 55 on a road trip. all highway driving. @ 200 miles I was only down to 3/4 tank. First quarter always goes the slowest though.

Worst gas milage = Full tank of premium in around 80 miles. Doing 104 w/cruise for 45 minutes in norther MN. Car did great until I stoppped. Took two hours for the engine light to clear. Probably not good for the car but fun!

My best was 450 or so miles off of a little over 16 gallons, while driving at about 77 between Minnesota and Indiana

I wish I could remember the cruising range but I have some statistics about a trip to/from Oberlin, Ohio from Wash. D.C. Lots of care in consistent fill-up procedure for accurate calculation.

1) 1993 Pontiac Bonneville SE normally aspirated (170hp): 85-90 mph --> 30.23 mpg!!! Best 1/4 miles: 16.28 at 82.1 mph. Best magazine time with 2.84 diff'l gear is 16.7 at 84mph.

2) 1995 Pontiac Firebird Trans Am 6-speed with borla exhaust (~285 hp): 85-90 mph --> 26.7 mpg; 61 mph --> 31.4 mpg. Best 1/4 mile: 14.002 at 100.3 mph for this setup. Best magazine time is 14.0 at 101 mph (stock).

3) 1996 Pontiac Bonneville SE/SLE */C (240hp): 85-90 mph --> 26.6 mpg. Hitting it full throttle on other occasions really sucks fuel down. Best 1/4 mile: 14.5 at 94.1 mph. Best magazine time on base */C Bonne is C&D 2/96 15.3 at 92 mph.

4) 1992 Lexus ES300 (185 hp): 85-90 mph --> 24.7 mpg. Best 1/4 mile: 16.57 at 83.1 mph. Best magazine time is C&D 2/92 of 16.5 at 85 mph

My best ever MPG was 40.1 on a cool fall day for about a 4 hour road trip with no AC. I was averaging between 65-70 mpg.

I have never been able to repeat that so I don't know how accurate it is. My best ever repeatable mpg has been around 36 mpg on several different day trips with some city driving.

It all depends on whether you're talking "City" or "HWY"! In the city I get about 300 KM BUT on the HWY I got 1/8th of a tank & went 450 KM on just that 1/8th tank!
