My engine calls for 10w-30, and that’s all I use. It is a turbocharged performance car from the 90s, with no emissions. Mainly an auto cross toy, but I do drive it to events. So I have never looked at actual racing oils.
I’ve just used Mobil 1 synthetic 10w-30. It shears out of the 30 weight range pretty quickly, and my valvetrain will also get noisy within 1,500 miles. It does see hard use, and I should probably be looking into a better oil more suited for a car that is seeing mainly abuse.
Any recommendations for something that holds a 30 weight better, or is on the thicker side of the 30 weight range?
