Interestingly meets MS-12991…

but 9 quarts = 2.25 gallons

@ $49.99/gallon * 3 = $149.97/ oil change

Not sure if it’s worth it over AMSOIL….

@biodiesel I eagerly await your expertise.

A good engineered engine design, components and machining shouldn't require some $50 a gallon oil for it to last. If it does, than it's a bad design to begin with. Just my opinion.

Just used up my last 10 jugs of QS that i bought for $15 a jug from 3 yrs ago. And, have had no issues. Might try some Valvoline heavy duty next.

Just used the last of the Valvoline European 5-40, was on sale for $22 a jug at Walmart.

I’ve been totally satisfied with Quaker State at $22 for a 5qt jug. I do use doc’s for fuel, air and cabin filters.
