I have decided to go backwards. My 2002 8.1L keeps eating oil even after putting in updated intake gaskets, and I am going to try conventional Valvoline. After talking to my father, older and wiser than me, he had a few examples of a few of his vehicles that consumed synthetic/semi-synthetic oil, but eventually took none when he switched to conventional. Only thing I can think of is it is dirtier and maybe accumulates at the top of the pistons reducing blowby.
I'm down, this engine was developed before synthetic oils were common and I am sick of adding oil. The intake gasket reduced it some, but I figured it won't hurt anything. I change oil at 3k. Anyone else ever have this result with old fashioned conventional?
