Since my father used to use Wolf's Head I asked about it, Pennzoil had acquired it years before. It was the same oil that was in the yellow bottles, same formulation. Pennzoil acquired Wolf's Head in 1963.

Looking around in the warehouse there were many private label brands as well as some national brands. The warehouse guy says it's all the same oil as comes in the yellow Pennzoil bottles, just a different label on the bottles. Just as NAPA used their own bottles, it was Ashland oil, otherwise known as Valvoline. That may have changed, but in the early 70s NAPA was all Valvoline oil, in their bottles.

Wolf's Head used to be an emerald green color, which usually indicates a high zinc concentrate oil (Brad Penn is green in color also). Any Wolf's Head oil made in the last 50 years is amber colored, not even close to the original formulation green colored Wolf's Head oil. I was 10 years old when Pennzoil bought out Wolf's Head, but I still remember my father changing oil, and seeing that green oil from the cans.

I really don't want to screw up the OPs thread talking about oils, but by the same token want to keep facts straight.

60s and early 70s is a heck of a time frame difference from the early 90s you speak about using. Pennzoil and Wolfshead oil was not Gulf oil in the 1960 & 70s. It was Pensylvania oil taken from the USA drillings. Throwing a name around means nothing.

I bought the 15W40 oil for the zinc amount, I could care less that the company that made it is Shell. The BP Oil Engineer (obviously not working for a US company), who I would trust anything he told me recommended the 15W40 oil from Farm Fleet as the farmers still wanted the SE oil in their tractors. It was over 1400 ppm of zinc. Great for Camshaft life.

Tom, I grew up in PA very close to the oil refineries, I've been in them to work on equipment, talked to people that have worked there for years. I'll take first hand information from employees, over a man that probably never set foot on any of the properties.

I really don't know why it is that you have the need to denigrate my information, to prove a point. If you choose to not believe anything I say, that's fine, but trying to make a mockery, on the forum, why?

Here's a quote from your text above:

"Throwing a name around means nothing."

I'm not the one that says, I know this guy, or that guy personally, and worked with so and so, on a project for ..............
