M1 10w40 4T starts at 13.4. Held grade last riding season over 5,345 miles in the ZRX1200. Two riding seasons previous it dropped just out of grade over a similar OCI. Stuck in between those two OCI’s, M1 20w50 V Twin went 5,065 miles and was solidly in the middle of grade. Can’t say enough about the M1 MC specific oils.
My local Walmart has the Supertech motorcycle and ATV oils selling for $4.98 a quart. Wonder if they are getting out of the MC oil business? Picked some Supertech 20w50 V Twin up to try some year down the line, but to this point I have not seen a UOA on any of those oils or able to find (maybe don’t know where to look?) a PDS on them. If there is a good ad-pack with zinc as the main contributor, I would go back and grab some more.
