MPG with 4.8L and 35X12.50 with 3.42 vs. 3.73 vs. 4.10 vs. 4.56...

I used to have the same size tires on my truck nitro mud grapplers with 373 gears stock 4.8 regular cab short bed 4x4 and I'm almost certain it's 4 speed automatic trams I believe I used to get about 12 to 13 mpg it does have alot to do with driving habits but I liked to haul ass show off and go off roading what size gears do u have in ur truck now

 

3.42

I'm thinking: See how it goes and then see If the change to 3.73 is worth it (12-13 is pretty good).

 

After my 2nd set of 35s were bawled I up the ainte and put another 6" lift on top to make 12" lift regeared front and rear to 4.88 yukon gears and put some 40/13.50/r17 Goodyear mtrs and amazingly I'm now getting 14 to 16 mpg. Doesn't make much since but I'm happier

 

Lmao. You can't be serious. Does someone tow you around to get that mpg? Sorry but you have severely miscalculated.

Ahahah for sure gettin towed around. Biggest load of nonsense I've read in awhile ahah.

 

No I didn't miscalculate I have superchip air intake throttle body spacer force fuel treatment used in every tank and I've clocked it multiple times and that's my average

Must be the throttle body spacer

 

 

 

Gotta be! Those things are almost as good as those tornado inserts.

 

I bet it runs 12s too

Idk what it runs haven't had it on a drag strip. Don't hate cause my truck gets better than it stock one. Your just jealouse

For sure man...So jealous of your 300hp 4.8 LOL. Why would I drive a twin turbo duramax when I could own something like that??? LOL

 

But nvm that, I pride myself in having the simple knowledge to operate a calculator and use simple math. you sound like a real winner.

Not hating man. Just telling it like it is. No gasser on the market will turn 16mpg with 40s, let alone a 4.8. Yours is no different. I would bet if you're lucky you get half that.
