Is penzzoil a good motor oil brand?

Some people have used it and experienced no problems,.. some people wouldn't touch the stuff. Here's what I learned growing up: The Pennsylvania produced oils(Pennzoil, Quaker State) all are what is called paraffin based. The oils that are produced in The Carolinas, and South and West Texas are carbon based oils. The oils that come from Oklahoma and the Midwest are somewhere in between. The paraffin based oils after being run in an engine tries to revert back to its original state... (wax). Carbon based oils(Exxon, Shell, Chevron, Valvoline, etc...) do the same thing,.. they deposit a thick black coat of carbon. The in-between oils do both... These are generally known as 2nd tier oils: ( Kendall, Phillips66, Amalie, etc..)


Nowdays all oils have so many additives and stabilizers the performance of each major brand of oil is all but indistinguishable from each other. I do know that Phillips 66, Kendall, the former Texaco, and 2 other American oil companies produce 100% of their oil without any mideast oils of any kind. I personally use Valvoline in the Pickup, and Lucas full synthetic in the bike....always had great service from both.Is penzzoil a good motor oil brand?

That's all I use. Plus you can get it anywhere. Pennzoil and Castrol are the same company, by the way. Castrol is usually synthetic. I don't see a need for synthetic unless I'm racing.
oil is oil. main thing u change it regularly and with the recommended viscocity.
