Can you mix oil weights?
Let's say you're at a point where you need to add a quart of oil.
You've decided you would like to finish this oil change interval at a lighter weight (eg you put in AeroShell W100, SAE-50, and now it's freaking cold). Can you add a quart of a (substantially?) lighter weight oil (presumably in the same 'series')? -- Ben Jackson http://www.ben.com/

All aviation oils are compatible, and have to be to meet the appropriate spec's. Otherwise, you'd be SOL if you needed to add a quart of oil and the FBO on the airport you stopped at didn't carry *your* brand/weight of oil. KB

Shell says you can mix grades of AeroShell as long as both grades are allowed for your engine.

Yes you can, but it might take a lot to make a meaningful difference unless
your engine is a big leaker. Mike MU-2 "Ben Jackson" wrote in message news:CQkJb.261117$_M.1211945@attbi_s54... Let's say you're at a point where you need to add a quart of oil.
