Thread: Really Quakerstate...com'on

What vehicle would last 300,000 miles using Quakerstate for it's oil? Their oil is crap. Talk about sludge.

Talk about Penzoil as well.

Penzoil? Ever since I started using Penzoil in the Honda I bought a few months ago, it's been cleaning it out. The rollers on the rockers where solid black before, now they're just speckled with black. This is just the conventional Penzoil too. I had to change all the oil seals cause they started leaking after cleaning the crap out just like most synthetic oils do.

Penzoil was notoriously infamous for their issues with sludging. Google "engine sludge", I bet most of the results relate to Penzoil. Now, like my prior post, the oil standard has been increased in quality. Run any oil you want as long as you replace it in the recommended amount of time.

When googling engine sludge, VW and Toyota engines come up the most. Looks like the Penzoil issue you're talking about is from the 70s when Penzoil came from Pennsylvania. Think it was more a result from people mixing it with Texas based oils. Always have been told never to mix oil brands. But for Synthetics, I run Mobil 1. Thinking of switching to Penzoil synthetic though.
