Seems as though I'm getting 25-35 miles less to a tank of gas. Does this seem about right? I go from "F" to "E" after going around 215 miles.

Yup, those who told you it wouldn't make much difference lied...

how ever much gas you put in your car is how much you divide by...make sure you do that. like i got 241 miles on 12.1 gallons..which is 20mpg

I only lost 3-4MPG at the most... his foot is the problem

i agree with HOSS... cliffy i know you are a genius, but i didnt see a huge difference... i got 24 on the highway and i average about 20 mpg right now, i think its his foot too

joaquinGT

Driving conservatively with 4.10s is harder than with the stockers, especially if the car has any exhaust work done to it.

In my last car, I lost 3mpg going from 3.27's to 4.30's. Having the 4.10's installed Friday in the 5 speed, so I'll figure it out shortly after.

Damn 215 for me was on a good day with 3.90s. I always got on it though haha

I saw no loss in MPG, I changed the way I drove unless I was playing around. I would start in 2nd from a light - skip to 4th or 5th right away. There were a few trips I made with 20+ mpg.

Stop downshifting & skip shift. Your wallet will be happy.
