I think the M1 vs. Subaru engines has to do more with the wrx/sti high compression engines.

I was planning on only using walmarts M1 long term as well, until I found kendall 0-w20 (which has almost identical specs to amsoil) for even cheaper then the M1.

Im sure any 0-w20 is fine with a regular oil change interval.
