Is full saps only an issue if you have catalytic converters. Or will it affect anything else. I ask because they recommend low saps for my car. Audi RS3
I’ll try the hpl supercar 5w40. Running AMSOIL 5w40 now fs. I honestly feel like the car performs better with oils like 300v or redline maybe it’s the ester properties.
They weren’t super helpful just basically said yeah run whatever the builder suggests. The builder uses Mobil 1 5w40 which I believe isn’t the best oil you can run in 5w40.
