I went from BMWs oil to AMSOIL 5-30 S2000 and find it the same. Actually I think im buring more oil with AMSOIL!
I don't know about even 7500 Miles, I change every 5000 miles!
Question: What is your take on Crankcase cleaners? I have the Forte Step 1 Crankcase additive and want to know if it is a good idea to do? I have heard it can be too harsh and cause more damage...my engine only has 50000 KM.
