2016 4Runner SR5

10,000 mixed city (~75%) and highway (~25%) miles. Quaker State Ultimate Durability is about twice as expensive as Walmart SuperTech and about half as expensive as Amsoil Signature Series. SuperTech is branded to Walmart by the lowest bidder, so I choose to not buy it. What's the thermal breakdown temperature of SuperTech? I don't know. QSUD oil costs me about 0.4 cents per mile. Gasoline costs about 15 cents a mile. I choose not to buy Amsoil, which is the most expensive and arguably the absolute best oil. QSUD is a high quality (or very high quality) oil at a midway price point which makes it my preferred choice.
SuperTech is actually a pretty decent oil especially for the price. It's not bottled by the lowest bigger, it is and always has been bottled by Warren Distribution, same company that bottles Amazon brand oil. Well known 90+ year old company so they must be doing something right. Not saying I care to run it in my 4Runner but I would absolutely run it in an older vehicle that I care less about.
