How Many MPG Do You Get?

[Kalifornia087]

'90 HF with 321,000 miles. Bone stock, super restricted, has lots of little leaks but still runs great everyday.

Average 38-42 in town depending on how I drive that tank of gas.
45+ on the highway.
Truthfully it probably should get better mileage being an HF but it's old and I never took the time to tidy all the small stuff up I've just been enjoying it too much.

What motor and trans are you running??

If your running the B16 trans you can't fix it with out doing gear changes in the trans.

I'm assuming you probably are, because with my B16 I had it was the same deal. If your not worried about losing power, throw an LS trans in it. Its not A LOT better, but better all the same.

4k @ 85 is an LS trans. What engine? RPMs are not inherently bad, you might try simply slowing down some.

My ls tranny does 3500k@80mph and soon to have b16 wonder how much of a difference in gas mpg.Guy I got the tranny from said @ 80mph car used to be at 5k .Whats the difference between jdm b16 and usdm?

car probably has appoxemitely 370000 miles, 40-45mpg (was 30 but then i cleaned/soaked the o2 sensor with gas for a night to try to fix it, well it didnt but mileage shot up higher) primarily driving on base, rarely drive more than 5 miles a trip unless i go off base. never been on highway trips so not sure what that is, probably 50+. car is a 93 civic vx
