So today, for the second time, a Mazda service advisor mentioned that Mazda doesn't recommend GTL oils (and he mentioned Pennzoil specifically). This just doesn't make sense to me but I would like to bring this fourth to see what do members think? I know we have a couple members that were working for Mazda and I also would like to pick their brains.
I really didn't also understand the reasoning behind it but he said something that the GTL oils run thinner and engines don't last a lifetime on these oils but that was the reasoning that was given to me.
Any thoughts?
