Pardon me if this has been discussed somewhere before...but I couldn`t find it.
My question is whether switching from Amsoil Synthetic back to conventional oil will do any harm. I did the first 1000 mile oil change with regular oil and went to Amsoil on the 5000 mile change. I have valve or lofter noise and I`ve heard it may be quieter with conventional oil.
