My father was a mechanic back in the days where we had service stations with a mechanic on duty. He always used Quaker state. .... That stuff will sludge up a engine fast.
As I got older I learned penzoil will do the exact same thing. I'm not sure but I think it is oil that uses paraffin that causes the sludge?
I may be mis remembering this as its been close to 30 years ago. But my dad was a mechanic and he saw it all. When him and my mom bought there 1993 Dodge Spirit, which was the first and only car they ever bought new, he used Penzoil in it for oil changes, and it either burned oil real bad or leaked, cant remember which, but when he switched to Castrol the problem went away entirely. They got over 200,000 miles outta that car, so the Castrol did its thing
