@SR5
Both look good but relatively speaking, MC is more impressive. It appears to be a very stout SynBlend.

Yes both have good looking add packs and I would happily use either.

But MC synblend has always impressed me when I have seen their UOAs here. Isn’t it the same thing as Kendall (but without the Titanium)?

Haha that Speedway oil actually looks pretty good! Good dose of moly and zinc

Yes. Or at least a Kendall product.
