There is another factor that is emerging -- the price difference between Mobil 1 and dino.
I bought some for an oil change on my motorcycle and about went into cardiac arrest. I forget now how much I had to pay for "quality" dino, but it was a lot more than I have ever paid before. Mobil 1 is the same price as it was when I started using it a couple of years ago. -- 1977 240D 1972 Honda CB-500K motorcycle If we couldn't laugh we would all go insane.
