What brand oil do any of you use for your cars? What has been the best and worse? If you have more than one preference what is the order you will go before using another brand.....here is mine

1. Royal Purple 10W-30
2. Mobil 1 10W-30
3. Castrol GTX 10W-30
4. Valvoline

Castro 0W-30. I wanted a thicker 30 weight for my DI turbo engine. UOA shows it's better than the 5W-30 castrol I was using before.

Pennzoil Platinum 10W-30 - Previous owner (2000 Avalon) has used synthetic since day one and changed it religiously every 3000 miles. I don't change it that often, but I figured I'd follow his product example. (Everything else he's done for that car have kept it pristine.)

Penzoil or Mobile 1. Not too worried or particular as i'll be swapping the engine in the somewhat near future.

Wanted to do that to a 1994 GMC Safari, sadly the engine gave out before I could of done the swap.

I'm caught between a coyote swap and or the plug and play 4.6 swap. I think the coyote would be a lot more fun

used to run RP as it was free from sponsor and it was great, but when I stopped being sponsored I continued to use it and had a oil test ran. shortly after I started to run mobil 1 as it was cheaper and also had it tested and the results were basically the same. so now I only run mobil 0w30
