The best I've done was 314 miles highway, average speed of 72-73 with 3-4 pit stops and no drafting, top down, cool and cloudy to mild sunny over the cousre of the trip, no appreciable wind.

 

I'm going off of my (albeit bad) memory here of fill-ups. I don't typically pay too much note to the amount I add because it never really was an issue, but I'm pretty sure 11.5-12 isn't overboard.

I seem to remember an old thread about tank size and it was like 14.4 or somesuch gallons. The odd size was due to it being sized originally in liters which didn't convert to a clean gallon size.

 

Bah, search is busted again....

 

i always get around 250

 

I'm glad there's folk out there getting the same gas mileage I am. The first few posts had me thinking there was osmething wrong with my car.

entirely city: about 220 (I work 3.5 miles from home but there's about 15 lights!)
all highway: about 275

I've filled at the most 11.5 gallons and that's when I'm sweating it pullling into the station. On a normal run, about 10.5-11 gallons.

 

I get usually 22-25mpg for regular driving (tons of vtec *cough*).

I once got 30mpg for a long road trip that also included a couple VTEC moments.

 

There are a lot of variables. Gas formulations probably differ by region, as does climate, altitude etc.

On a recent x-country trip from Chicago to NorCal in my fiance's '96 Integra, we got our lowest avg mpg (27-28) in Iowa and Nebraska. There, the midgrade gas is the cheapest, but has high ethanol content which reduces mileage. We got our best mileage at altitude in CO, even with a lot of hill climbing and about 300lbs of luggage we were never below 33mpg, and hit a high of 40.3 on one tank through rolling hills. This agreed with my previous xcountry trip in my '88 Prelude, when I also got higher mileage at altitude. I can only guess this was due to less fuel to maintain stochiometric ratio with less air, and possibly less air resistance.

In the S2k I drive a mix of city/hwy and typcially get 240-250 (~23mpg) but if there are a couple 30 mile highway trips I will get 25mpg (260-270). Longest ever on a tank was 300, best calculated mileage ever was 30.3.

It largely depends on if you're auto or manual.

I wish they could have put a larger tank in these cars. I can't even make it to Vegas.

 

I guess a part of the question would be: are these numbers with the top up or down?

 

damn you guys that see high numbers are lucky

i dont tihnk i ever hit 250 before, highest i remember is like 220

usually hit 180-200 and thats right before the light comes on

but i prob vtec 100 times and stay in higher rpms all day long
