Does 4.10 gear change your gas mileage?
Hey all, I was just wondering this since the next thing I will be saving up for is a 12bolt. How does the gearing change your gas mileage? My TA is a daily commuter and Im in a lot of bumper to bumper here in LA so I dont want to do anything that will kill my mileage. Is that affected at all?

I drive alot of bumper to bumper traffic daily with my 4.10s, and milage has not changed much. When cruising at 70 im always in 6th gear as opposed to 5th wiwth the 3.42s. The only place that milage really suffers is on long trips at 80 or so where i used to use 6th gear with the stock 3.42s anyway. Whats a dollar per tank compared to the performance gain!??!

Your mpg will go up all around the charts unless you keep your foot into it. If you have a lead foot, your mileage will go down. When your normally driving, you're shifting at close to the same rpm, but you're going faster then you normally would, meaning leass gas to get you to speed. If you're foot is always to the floor, you're gonna use more because you're turrning more R's to get you to top speed.

My city mileage improved 1 mpg to 2 mpg depending on how I drive it but dropped about 1 mpg on the highway. So it has stayed about the same overall. I've only checked it once or twice though as its just too much fun with the 4.10's not to stomp on it occasionally.

I checked out what the rpm difference was between 4.10's and 3.42's. There was only 400 rpm between the two. My brother has the same set up except for he still had the factory gears. Also I have noticed hardly any difference in mpg either.

should not affect mpg all that much. well, if you can keep your foot out of it anyway!

I skip gears all the time. I go from 2nd to 4th, sometimes 1st to 3rd. It all depends. Sometimes I just want to jump off the green light, but by the time I'm shifting gears I'm already at the posted speed limit, so I'll go from 1st hard, then ease it into 3rd oe 4th.
I'm planning on getting 4.10 in a few weeks too. I imagine that I will get better mpg because I do a lot of 60-70mph driving, and I can't ever really use 6th because it's just too low. So with 4.10 I should be able to use 6th more, and thus less rpms and better mpg.
