Most fuel efficient RPM to shift?

[phiend]

Once upon a time I owned an 89 accord 5 speed. It came with the owners manual. In the manual it listed the most fuel efficient shift points.

So now I have an 90 accord 5 speed, but it didn't come with the manual.
I'm wondering if first, the 90 manual came with this information also, and second if anyone could share it if it did.

the lower ur rpms stay the less gass u use

i shift at 2500rpm. but thats if im going slower and cruising. if im driving more faster and around freeways than ill shift at like 3-3500rpm.

2500rpm when your cruising.
3500rpm when your feeling agressive.

I let the computer decide, but its usually around 4k

My 90 owners manual says to shift at 15mph, 28mph, 41mph, 52mph for best fuel economy and emissions control.

I find that those points are usually around 3k

Thanks, that is exactly what I was looking for.

Another equally important but often forgot mileage technique is using light throttle applications. If you use 1/2 throttle and shift a 3k you'll probably get worse mileage than someone shifting at 3.5k but barely touching the throttle. I follow the shift speeds in the owners manual and with really light thottle applications I got 35.4mpg on my last tank, that is with a F22B DOHC running on a P39 ECU.

[deevergote]

That is very true. I got an extra 4mpg with my gas-hog GTP by using light throttle and not letting it go above 2500 (which is high for that V6)

So would giving 3rd a lot of gas to get up a hill at around 30 mph be less economical than using second and lighter on gas? I just feel like second is up around 3200rpms which seems a bit steep.

It depends on just how much the throttle percentage difference is between the two gears, I shift higher when ascending steep hills to avoid using more throttle in the next gear and due to the quicker loss of momentum when a shift is made while going uphill.

in my mazda i would try to shift under 3k. in 5th gear by 40mph
