95yeti

really how is that for you

93XJLI

awesome. i love rotella oil, i run the syn 5w-40 in my subaru. i have to run slightly thicker stuff bc i have not-so-great rings in the 4.0.. but i've never had a problem with it and i run it year-round, just gotta be easy on it til it warms up a bit. i used to burn a lot of oil off but the thicker stuff doesnt burn as easy, and it quieted down the valvetrain a whole lot.

95yeti

i need something thicker cuz i out 5w 30 in for some reason and when it warms up i have really low pil pressure

give it a shot. i ran 5w-30 last winter and i burnt off all 6qts in 2 weeks.

Im running val. max life 10w30 now. Mines got 180k on it. I just started using it and ive noticed a difference in my oil pressure. I used to use penzoil 10w30 and i was pushin 80psi running and 40psi at idle. Now its running 60psi at 55mph and 40psi at idle. Thats what the gauge is tellin me anyway.
