If you don't trust, then really ... don't buy.
Products that exclaim exceeds, are always a smarter buy than one that says meet, in the most common, mid-priced market and driving on extended OCIs and especially with a GDI / TGDI engine.
My twice-a-year OCIs for my two vehicles costs me an additional $32 per year. I paid $23 for Ultra versus $15 for Supertech. That's peanuts change in today's world.
