Was at sams and saw somthing neat, Aviation oil?
 

At my local Sams in the aisle with all the car stuff next to the various engine oils they sell by the box I saw this:

Attachment 758740

Has anyone tried or theoretically proved or disproved the use of this? :scratch: I know I see the 100w.

Ashless! Really? It's SAE 50 too hmmmm.

shell offers a much better weights than 100w listed on their website.

you might wanna look at why its 100w in a plane but its 50 SAE

That's not the same as conventional oil. Only General Aviation uses ashless dispersant and mineral oil.
