Oil Myth #3: The brand is what protects your engine.
It's not. The specification is.
The API rating on the back of that bottle — API SP, ILSAC GF-6, GM dexos1 — that's the standard the oil has been certified against. Those specs require real testing. Pass the test, earn the rating.
If two oils carry the same spec and the same viscosity, they protect your engine the same way. The brand on the front label doesn't change that.
Where brand loyalty actually costs you: when people overpay for a name and ignore whether the oil even meets the spec their engine requires. That's the part that matters.
Check your owner's manual. Find the required spec. Then buy the oil that meets it — at whatever price point makes sense for you.
