I was reading on another forum where an ex Amsoil dealer switched to Mobil " I think " after finding his engine was internally dirty @ 80k miles using the 0w-30 .
What do the experts here think would cause this ?

Dollar store oil will keep an engine clean at 3K OCIs and with only 80K miles total.

Sorry Jelly too broad a statement to state as synthetic is NOT what it was 20 years ago!!!! It's the synthetic base...speak of today...I'll retract that statement of Amsoil as tech in synthetic is advancing better than we think...My apoligy!!!!
