question re: Gas Mileage,4th and 5th gear
 

If I'm driving my 99TJ ,(straight 6 cyl), on level interstate and my
4th gear RPM's are exactly 2000 rpms at 69-70mph and my 5th gear RPM's
are exactly 2500 rpm's at 69-70 mph, which gives me better gas mileage?

Re: question re: Gas Mileage,4th and 5th gear
 

Your 5th gear RPM's will be lower than 4th gear at the same speed.

Re: question re: Gas Mileage,4th and 5th gear
 

You're dyslexic. How much you have to press the accelerator pedal
down to maintain the speed will give you a big clue. But if you want to
brag about mileage you're going to have to keep it down to about fifty
five, were wind resistance doesn't play a roll.

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.

Re: question re: Gas Mileage,4th and 5th gear
 

You should play around and see. My engine's 'sweet spot' is between
2300 and 2500 rpm. I get the best mileage there with tons of instant
pull if needed.

Re: question re: Gas Mileage,4th and 5th gear
 

What Mike said about the sweet spot. I suspect that 2000 rpm will be a
bit low and 2500 a bit high for best mileage.

Re: question re: Gas Mileage,4th and 5th gear
 

You have that backwards, the higher engine speeds come in the lower gears.
5th gear will spin at 2000 while 4th spins at 2500.
