No!

Most of our flyers don't use any after-run. Petroleum based "after-run" oils do not mix with methanol-based fuels. So,we definitely don’t recommend any petroleum based lubes. Our built-in after-run oil is one of the most universally recognized features of our fuels.

If you think ATF and Marvel's Oil are not petroleum based go look on the warning labels.
