I have been trying to figure out if there is difference in SAE 90 and 85w-90. Besides the obvious difference in the numbers, is there a difference in the type of oil. My scoot calls for SAE 90.

SAE 90 and 85w-90 are essentially the same... the "85w" in "85w-90" just means that it's a multi-viscosity oil, and acts like an 85 weight oil at 32 degress F - the cold temperature rating that's denoted by the "w". At 212 degrees F (the hot temp rating), it acts just like a single-grade 90 weight oil. www.substech.com/dokuwiki/doku.php?id=gear_oils#viscosity_of_gear_oils Bob |

This was exactly what I was looking for. |
