Awesome, good to hear a couple of good out comes!

 

I dunno I've got 33s on mine and 12mpg is like my worst around town mileage with a 5.9
I get like 15 on the highway.

 

hey cereal, What gears do you have in that thing your running? 4.11's?

 

I ran mob1 the first 2 oil changes then at 18k switched to amsoil 25k and change it every 7500 miles, comes out pretty clean, make sure you use amsoil filter roughly 15 bucks but worth it.
I also run the severe gear in my front and rear diffs. The severe gear is rated at 100k miles, just drain and check for those Fing c clips and then refill.
I'm in the low 30k right now on my truck

 

3.55

 

Amsoil is one of the best oil's available (my opinion) but unless you run it for extended periods (15K+) I don't think it's worth the premium price.
Mobil 1 or Pennzoil Platinum will protect just as wellif your changing in under 10K.

 

Are you guys using AMS 10w30 and what millage?
