Synthetic is a waste of money.It breaks down just as fast as real oil does.I change mine every 3,000 miles.
Negatory.
Amsoil and Wix every 10k, and I have a whole bunch of used oil analysis to prove it has no peer.
We had a Chem lab at work and they checked Amsoil and Pennsoil after 3 thousand miles.The Pennsoil had actually broke down less then the Amsoil.So believe what you want.I know better.
Then you used oil that was spec'd wrong. I've got dozens of UOA's that say you don't know what your'e talking about, making it up, or lying.
JG thinking of running Amsoil in the new truck(Gas) which one do you use and did you ever try their expensive oil filters?
My Ram Ecodiesel calls for the Amsoil Euro 5w40. I've got 3 UOA's with it and it's done very good at 10k interval. I have not used the oil filters so I can't comment on that one. If you decide to get the oil, sign up as a preferred customer and get significant discounts online.
It is irrelevant what you think. What matters is the TRUTH.
