FWIW, 15W40 SF seems to be the lowest/oldest widely available grade of oil you can buy today -every noname petroleum products distributor and gas station will have an offering in that weight and grade, so I don't know if that's why they chose this specific type in the manual.

15w40 is just the Viscosity, you can even find them in SM,SL and SJ. What is old is the SF specification it's from the late 70s and early 80s, my guess is that they put SF, because newer specs may have addictives that could harm the clutch. http://www.pqiamerica.com/devilsindisguise.htm https://www.api.org/products-and-ser...s#tab-gasoline Down the road, imho we should stick with oils made for motorcycle that are either JASO MA or MA2. |
