truly great oil
Would RecommendRebuilt motor that had been run on another oil ( motor was full of sludge and filth) Put 22,000 miles on the new build with only Quaker state, pulled it for some upgrades and it looked clean as the day I put it together. I won't run anything else.

No more clunk clunk
Would RecommendSo I nagged my husband, my car makes a funny noise, so he finally put a stop to it, running low on fluids, and just plain needed some TLC. The car is 16 years old and still running like a gazelle. The only noise I want to hear is the music on my radio.
