Most miles per tank of fuel

I was mistaken, it was in the states.
Or how about 36.6 mpg for more than a full tank?
On the way back to OH from FL my total trip mileage according to the DIC (driver's information center) was 36.6 mpg for a total of ~750 miles. I know this sounds a little ridiculous and I thought it was probably closer to 33mpg. So, I actually reset a trip meter and filled my gas tank to the fill tube at the one gas stop I made. Then when I got to Bellbrook, I stopped at the first gas station and measured the fuel it took to completely fill the tank to the fill tube again. That leg of the trip was ~365 miles, and I used 9.4xx gallons. Down to 4 significant digits (I did have both the mileage and fuel consumed exactly), the calculated fuel mileage came out to 38.79 mpg. That seems absurd even to me, but I assure you that my math was correct. So the only thing that could be throwing it off is if the vette is not registering the correct mileage. I think it's probably pretty accurate, but I'll find out next time I take a trip along side someone else. I think the keys to my awesome mileage included staying in 6th and averaging probably 55 mph the whole way (staying between 45-65), and drifting down steep enough hills in neutral where i could pull the car out of gear and let the RPMs drop to idle while the car maintained speed or accelerated due to gravity. It wasn't an all-out attempt to maximize fuel economy or I would've kept my speed between 45 & 50mph. But other than the speed I'd say it was about the best I could do. I'm sure I pissed off a lot of people on the interstate, though.
The moral of the story: I love my LS1 vette!
Later,
Chris

when i my 2003 z06 was almost stock with only mod's lt headers/corsa exhaust and a vararam intake setup i drove my house to albuquerque, new mexico which is about 346 miles and still had about a 1/4 tank of glass left...now with a forged motor and a supercharger i could prob not do that

Once drove from Scranton PA home to Portland Maine. 400 miles. Bone stock 98 A4.
Had 1/4 tank left. Very impressive considering all the mountains in PA and western NY.
What was more impressive was setting the cruise control at 75 and watching the transmission STAY in overdrive climbing the hills, without downshifting... The same drive in my 15 Honda pilot with cruise control on, kept fluctuating 5mph slow or fast trying to keep the same speed, and shifting constantly. The power and programming of this 20 year old engine and transmission continues to impress me.

The C5 coupe is the most aerodynamic of the Corvettes (except when popups are up). FRCs and convertibles are less aerodynamic, and newer gens have traded aerodynamics for increased downforce.

You don't have to drive like a jackass to have fun. I'm simply saying, if you are getting 400 miles on a tank, you are probably 6th gear with cruise control on. I can do that in my Cruze or Equinox.

Yeah, so when I'm doing a 500 miles drive should I leave it in 3rd so I can haz race car feel?

Not all of us have Corvettes that are weekend only or garage queens.

Since bringing my 03 Coupe Auto 4 home on Mar 29, 2017, stock cept for exhaust. And 109325 on the clock. Best mileage was 25.5 worst 19.4 Highest gallon fill up was 15.5. Last fill up was 15.1 with the reserve fuel light on. And 115533 on the clock. I just love cruisin' down the back roads at 50 - 65 mph with a very seldom I 10 run to 80 mph.
I do keep a log book in the car , truck, and both bikes as to fill up's

Pressing it more than I would like to but I've learned from experience. In '71, my wife and I were driving from Florida to Indy for the US Nationals in our prepped '69 Z-28. With 4.88 gears it drank fuel pretty quickly (if I was lucky we could get almost 12mpg). The fuel warning light came on (about 10pm, of course) and we looked and looked for a gas station without success. (This was before all of the 24-hour a day stations). Finally, we found one open and immediately pulled in. I put 18.2 gallons of gas in what was listed as an 18 gallon tank. I jokingly say it's because the cross ram carb system had such big fuel lines that served as my reserve.
Since then, I've tried to be much like Pounder and not let the tank get below 1/4-1/2. Glad you get much better mileage than most so that you could make it to the station.
