Horrible Gas Milage!

One time while driving 275 miles from my grandfathers last summer I filled up with non reformulated gas up in his town. I drove 75 mph all the way home, and got 38 mpg on that highway trip, 1 better than my mom did in her 04 civic, this was before I started even trying to change my driving to get better mpg; I guess you could say that car was a freak. If I drove that car like I drive my civic now, I would say averaging 33-35 mpg city would be very attainable.

Damn that Automatic Transmission! They both have the B18b1 engine and I have the options too, but geez. I was averaging 26mpg in a similar situation before I started FE mods. I can't seem to crack 32-33 for a tank with most hypermiling techniques!

I need to re-think a few things. (grumble)...

If you can find a cheap hydro LS tranny I would say swap that in. I dont know how much those go for, but the old cable trannies are pretty cheap; probably because the 3rd gear synchros are bad in about 98% of them

Well, I know the thread has been dead for a while, but the other day I squeezed 24.9 mpg's out of it. Ive raised the tire pressures 4psi all around and im going to try coasting some too for this next tank. I think I drive almost all city, so in retrospect, maybe 22 isnt so bad. Are hypermilers people who get 20% above EPA rating? Id have to get 31 mpg to be a hypermiler. I only got 30mpg once (400 miles out of one tank), and that was all highway @ 80mph with a fully loaded car. I dont think i can be done...

Not to fear though, I ordered a Honda Fit on July 3. Base model with a manual tranny. That should get much better milage!

to the Fit.

And I'm sure you can do the hypermiling thing, just give it some practice and you'll get there.

If you go back to the stock cam you will probably pick up some mileage. Most cams kill city mileage. My Camaro's mileage got cut in half with a cam swap and no matter how easy I drive it I can't get it up to 10mpg anymore where it used to get 25mpg driving it pretty hard.

I would say if the power increase from the cam isn't that important to you then go back to the stock cam and send that aftermarket cam in to be ground down to lower lift and duration than the stock cam and that should easily get you 5mpg over stock.

At the time I wasnt concerned with FE at all, so nothing.

Well, it just goes to show that we all start at different places in the FE game. The fact that you are here is a good first step. The numbers themselves aren't all that important. Improvement is what matters most. Welcome! Fornow, just shoot for 30 then go on from there. Little steps.

This is a dangerous thing to say. Unless you think FE is completely a game and the environment/economy/urban sprawl, waste, blah blah are not factors in anything.
