Simple oil question here
Simple oil question here I've been using mobil 1 5/30 for the whole life of the car. It has almost 80k on it now and it gets driven hard. Should I be switching grades with the miles I have on it? Is amsoil a better oil? I've heard people getting quieter engines from amsoil?
Mobil is good oil, but I would recommend a diff viscosity. 5w30 is on the thin side with the mobil. I would recommend the 0w40, or I have heard they have a new 10w40 now in the new formulas.

I've been using the 5w-40 for a while now with no real issues. I don't do the analysis thing so couldn't give you any numbers. It's starting to get cold here and I have a bit of a knock when it's first started. It goes away before long, though.
