Oil Filter and Oil brands

[lgndryhr]

I would be more than happy with 15, I am getting like 12 in town but just short trips. Road trips to SoCal avg 14 to 15 running General Grabber 35’s which I think are pretty heavy, Mobil 1 oil and Costco premium fuel with a JDM tune. May try either Redline oil or Amsoil next oil change. Anyone get a mileage boost with a certain brand of oil?

I swapped to Pennzoil Platnium and got better results. I too use Costco gas. I fill up with 93 octane gas. I run BFG KO2's in stock size.

And you use Costco gas?
What type of gas are they running

As far as I know it’s all the same just some gas has more of the engine cleaning additives it is a “Top tier gas” has to exceed certain standards also run Chevron fuel and no difference in mileage if anything a bit better with the Costco. Both are premium grade 91 octane can’t readily find 93 here.

Manual says 3.5 requires 5w30.

OK, makes sense I got the 6.2 guess I am going to try the Amsoil SS 5w20 see if the mileage improves any probably dump in a jug of the P. i. gasoline additive as well. probably do the Wix filter.
