I think that might have a lot to do with some of these stories.
 
Got some new ones. This is from a guy who had a stuck lifter and
everyone he talked to blamed Pennzoil.

"I was talking to my son, who is a mechanic, on Tuesday afternoon about what was going on. He asked what kind of oil I used. I told him Pennzoil as that is what they put in at the lube shop. He said that he had heard of many problems with Pennzoil gumming up engines. Well that was news to me. I thought all oil was basically the same.
When I picked up my van later on Tuesday, I asked the mechanic if one oil is better than another. He told me what kind they use and then said, “just stay away from Pennzoil.” He went on to tell me that it is paraffin based. He said if he was tearing an engine apart he immediately knew if that kind of oil had been used.
It sure made sense to me now. That explains why the problem happened when the engine was cold. That paraffin sludge gummed up my engine.
Last night at church, I mentioned what had gone on and one of the old guys, an engineer, asked me if I knew why it happened. I said paraffin and he replied that it’s the Pennsylvania oil. I guess Quaker State is the same.
So, I learned a lot in the past few days. Why don’t they teach us these things in school? From now on, I will be careful of what oil I use. The shop used Mobile 1 and I have heard Castrol recommended too. Now I hope that my engine will be okay. Time will tell if the damage can be completely reversed."
 
Amazing in the last 50 or so years advertising claims for motor oils have not change very much have they. Thank you for sharing I like this advertisement. Where did you find it?
 
Yeah if not for the '56 Buick pictured, one would almost think it was a modern day advertisement...

It is in the March '56 Popular mechanics... I have several of these old mags, I'll look in the next few days to see what else I can find...

I found this on a Cherokee form.

"Pennzoil use to be a parafin (sp?) based oil. But in the early 2000's they went to a pure base.I still do not use Pennzoil because of the 'previous' base stock experience-I worked in a few machine shops in different states and have seen all kinds of things......Fords never liked pennzoil. It created massive sludge even w/ routine maintenance. I have seen engines with almost 200,000 that used synthetics since new and didnt need ANY machine work on the block or crank/rods. Here is some (actually ALOT) of reading regarding oils,viscosities,mineral vs synthetic...etc.
Good Reading!"

With some link to a article written by some hass guy.
Also I better get the Pennzoil out of my F150 it does not like it.

This was posted on the same topic.

People over-analyze brands of oil.

If you want to see a really obsessive discussion, check out "bobistheoilguy".

If you use a major brand of oil, either synthetic or dino, use the correct viscosity for the temperature range you are using the vehicle in, change it at a reasonable interval and don't use an el-cheapo filter, you will be just fine.

I've got other stuff to worry about.............
