I'm wondering if anyone knows what conventional oils have shown the best numbers in a 5s-fe (2.2L) UOA? I am not interested in any synthetic. (Please no amsoil recomendations, I have nothing against it, it is just readily available to me.)
My car currently has 217k, though I rebuilt the engine at 165k. (Used short block with 35k from a 2001, new rings, rod and main bearings, new valves, and oil pump.)
I can't seem to find any used oil analysis for the 4cyl with dino.
I ran GTX 10w30 exclusively till 4 oil changes ago when I ran Mobil Clean 7500 5w30 1 time, and the engine seemed louder. So I tried GTX 5w30. Then Formula Shell 5w30 with the V6 filter(Purolator L10241). And the same shell and filter again this time.
Thanks in advance,
Justin
