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,
