I wanted to use that expensive Yamaha stuff for my last change, but it wasn't available off the shelf. The dealer said they could order it, but not until they had something like a $3,000.00 order in the pipeline. Ordering the Yamalube on-line myself was ruled out by shipping charges on top of the already outrageous price, putting me in about the same position as the dealer. So I picked up a quart of Valvoline synth stuff at the auto parts store and put her in the punkin.
My old oil was also clean when I changed it out, with no metal on the magnet. The dealer had been doing the changes up till then, under contract, so I don't know what brand it was. It looked and smelled like dyno oil.
