Re: question re: Gas Mileage,4th and 5th gear
I think you mean your 4th gear rpm is 3000....

Re: question re: Gas Mileage,4th and 5th gear
You have your rpm's reversed, but anyway, the answer depends on if you
have a head wind or tail wind. If I have a tail wind, 5th on level will give me decent mileage likely. If not a hurricane on my ass, I use 4th and get 5 mpg better than 5th for an average highway run. It comes down to how much gas pedal is needed. In 5th, I have to floor it for wind or hill changes, in 4th I only have to twitch the pedal. But in my case I have 3.31 gears turning 33's and 4th gives me 2300 rpm at 65 mph which results in 23 US mpg.

Re: question re: Gas Mileage,4th and 5th gear
yep, I was back asswards on my gear/rpms and I apologize.
I thought I read here somewhere that my straight 6 somehow did better on gas if the rpms were higher. That was what I was trying to question. Now,if you want to flame me for not being a gearhead, go ahead. |
