Actually, if I tucked in behind you at 90 mph I could pull between 50-60 mpg the whole time and wait ya out! If you pumped 35 gallons in your tank and I put the usual 9 gallons in mine, I think by 400 miles in I'd be driving and you'd be walking
Aw come on! lol that's cheating!

are you sure about over 40 at that speed? I'm just asking because I thought that 4cyl engines start using much much more gas relative to V8s at high speeds

No, 4 cylinders don't even get close to a V6 at high speeds. To maintain 79 MPH in a Honda Odyssey it uses about 3.5 Gal/hour. For my Civic to maintain 79 MPH I use about 2.1 Gal/hour. That is using Cruise Control, which is less efficient than my foot, so if I was using my foot I would probably consume about 1.5 gal/hour maybe. The Insight is a 3 cylinder, so they will be using even less gas at 79 MPH. At 90 I'm not sure how any of our cars would handle, if we were going 800 miles at 90 MPH. Doesn't seem too safe in my opinion.

RPMs don't really matter when you are driving at high speeds, by that I mean that you can be at 2400 RPMs and using 1 gal/hour, or at 2200 RPMs and using 2 gal/hour. Both of those RPMs would be used to maintain a speed.

Don't be embarrassed about this tank's average though, we all have those rough patches in MPGs that we decide to have a little bit of fun. What I keep reminding myself of is that I don't need to get high MPGs all the time, although it would be nice, I just need to get high MPGs on things that I do everyday (school, home, 7/11, etc) but I can get whatever I want when I do abnormal stuff (movies, sporty driving, driving other people around, etc). As long as I don't waste too much gas I'll survive, and as long as I have fun while I'm "wasting" it, I don't consider it a waste.

Save on things that you do everyday, and spend like crazy on the things that make you happy. Just don't make a habit out of doing those "happy" things, just every once and a while.

Busted in Va means both trucks now belong to the law enforcement agency and he would get to keep paying for the truck he no longer owned. I doubt he would be laughing.

Huh? Well my truck had been paid off for almost 8 years now and we raced on private property in the middle of the country side so I don't really see a problem

Okay, just asking because engines like mine eat about the same amount of gas unless you are hitting it full power. Then the injectors just spray like madmen....

I here ya on the tank fails, been there a few times!

My slightly modified Duramax will get decent fuel economy for such a heavy rig. The problem is the only way to do that is to keep the skinny pedal off the floor.

There is nothing like running the 1/4mile track and looking down at the instant MPG reading on the dash and seeing it going between 1-3mph the whole time

Last night on the way home on I-4 I was in a semi's air pocket most of the trip until pretty close to my exit. At 75 mph on level ground (with a passenger) I was averaging almost 100 mpg behind the truck with about 2K on the tach. I got about 50 mpg after he switched lanes, just long enough to see what I'd actually get before I backed off the throttle. I know the tach jumped a bunch, but I forgot to check to see how high.

I'll probably never know about the 90 mph without an escort, I'm just guessing at the 40 mpg, but I'm sure one of the other Insight owners could verify it or call BS. My car has 209,000 miles on it and I need it to last, lol!
Unless I had a blocker like last night of course. Then I'd probably still get 75 mpg at 90 mph, and probably be at 3K or under.
