I hate to start an oil thread but........I'm wondering what people are using in their 45's? I have both M1 0w40 and castrol syntec 5w40 sitting in my garage, this is the first oil change since I've had the vehicle and was just looking for some input.
Cheers
Andy

We have quite a few oil threads. Pretty much all of them show that most of us use Mobil1 5w-30.

Regarding oil weight, I believe most in the U.S. use 5w-30 because its a good balance for moderate temps. Some of the folks up north where it dips into freezing temps might use a zero viscosity. Down here in Arizona I use either 5w-30 in winter or 10w-30 summer.

Regarding brands, most use Mobil 1 fully synthetic because its a good quality and easy to get (Walmart is the cheapest in 5 gal jugs). The more discerning owners use brands like AMSOIL (have to go through an AMSOIL dealer) or Royal Purple. I use Mobil 1.

a member from infinitiscene stated that using valvoline synthetic 5w40 stops the oil burning problem in our 45
Well if a member on infinitiscene said it, you can take it to the bank. :wink:
