230 Oil Change - Everyone has an opinion

[68gmsee]

Agree that there is a ton of opinions out there on oil for engines. Everyone has one. Some opinions get passed down through the generations others through actual experience. Pennzoil is a good example. Several years ago I read an article about the Pennzoil problems and, yes, they did have a problem years go but it was rectified, however, the dislike for the oil persists. I personally haven't seen any problems with it. I owned an 86 old that I used Pennzoil on and it went over 340,000 miles without an engine problem other than routine maintenance.

I have owned and worked on my own and other vehicles for over 40 years and have used Exxon oil, Castrol, Mobile one and Pennzoil mostly. I drove a lot of miles before retiring and most vehicles went way over 200K miles before trading them in or selling them. What I found out is that if you follow a good oil changing routine schedule and stay with the same brand as much as possible you should be okay. I usually change the oil and filter at no more than 5K miles and every 6 months on my 68 GMC since I don't drive it that much.
