This week I stopped by the local Suzuki dealership to inquire about some new tires for the s40 and a recall issue for a v strom 650. They have a stator recall for that year. I asked him if I should bring the bike and oil? He asked if I used the Suzuki recommended oil and I mentioned I used Rotella. He looked at me kind of funny and said: "ain't that tractor oil?"
I said yeah but it is JASO certified, good for clutches, and has some zddp. I am surprised by how many people don't realize what an outstanding product Rotella is.
Best regards,
