No, of course not!

The entire "wax" or "sludge buildup" issue about Pennzoil is always 100% anecdotal. Someone has a friend whose neighbor's uncle once long ago had a car that had all kinds of waxy sludge and supposedly the guy used Pennzoil. I can't put much stock in those kind of stories.

The Chevy Beretta in my signature was purchased brand new by me in 1991, and I used Pennzoil 5W30 (and occasional 10W30) exclusively until the car was wrecked courtesy of an 18-year old who wasn't paying attention in traffic. 318,000 miles, and the cylinder heads were spotless; no wax or sludge. I've posted the pics here before.


Understood. Yes, like I stated earlier, my 1991 chevy cavalier had over 225,000 miles on it. When I bought it, it had 30,000 miles. From that point I used pennzoil 5W30 like you. The only reason I got rid of it was it wasn't worth fixing everything that was going wrong. Brakes, muffler, leaking radiator, etc...

In the 60s-70s some oils were much worst at forming slude than others. For example I used Q Stare in a 64 valient fo 2 yrs. 2000 OCIs and had to scoop out the sludge with a spoon. Also Pennzoil formed sludge badly as well. However Valveoline did well fighting sludge as I remembered it.

This is as bad as the american cars fall apart in 20,000 miles and foreign cars easily last 8 million miles comments.

pennzoil = wax

I got a new 1984 Oldsmobile company/business car. The dealer service manager warned not to use Quaker State as it would sludge terribly. Since it was serviced under contract, it got Havoline oil and Texaco gas, OCI 3000 miles. At about exactly 50,000 miles, the oil filter blew completely off the engine. When it was taken for repair, the engine had about 3/8 inch of white paste all over the valve area, valve cover, the oil pan looked like it had lithium grease in it. I don't know why the engine never overheated.

Both the chemistry and technology of refining has drastically changed in 25 years. The stories I hear about sludge are "usually always" associated with pushing the OCI, coolant leaks, PCV valves, or driving a vehicle way beyond its design parameters.

Not to call penzoil bad ( I am using PP) but one instance of a company staying in business is FRAM. I do not hear or read a lot of good thing about their filters.

I have not seen any documentation of fram failures. We may not like the construction but they appear to funtion well.

most of what you read is they are overpriced for their inexpensive construction. you don't hear rumors over and over that a Fram killed killed an engine.

Fram sucks
Pennzoil causes wax
American cars suck
M1 protects 8x worse than CE,
5w20 is too thin
Synthetic causes seals to fail

what else we got?

LOL.

Time to start a BITOG urban legends thread.

Wow! Put that post on the main BITOG page and the forums can close down. No need for them now.

With anything, if something works for you, and you're happy with the results, stick with it and don't worry about what other people think. In my case, I've never had issues with pennzoil. Until I do, I'm going to use their product. It's that simple.

 

[ZZman]

That is the problem with these engine?Pennzoil talks. Were these engines sludge prone anyway? Were other maintenance issues addressed on time that could have caused or stopped the sludge or "wax" issues.

Oil has changed drastically from the old days.

Saying you don't want to use Pennzoil because of some story from way back in the 60's is like saying you don't want to use Windows Vista because Windows 95 was so bad. Windows has changed and so has oil.

 

[peterdaniel]

Windows still sucks.. always has and always will. And if you disagree, you are simply in denial and you know it.

Older cars simply ran much much colder. No chance to burn off the contaminants.

I had a 1966 VW that was born and raised on Pennzoil with Z-7! After 42 years, the heads were spotless. SHe changed the oil every 3K miles and since it was an aircooled VW, it got plenty hot enough to take care of any contaminants.

And she also checked the oil. Alot of people simply do NOT check the oil level and then they let it go too long between changes. The oil overheats and voila! You have sludge. Add that to not heating up enough the other times, not changing it enough and of course the oil composition of yesteryear and you have a perfect sludge storm.

FWIW, back in the 60s I remember being told that Pennsylvania grade oils were 'paraffin based' while others were 'asphalt based' and that Pennsylvania based were better. Oils proudly boasted Pennsylvania grade if they were and some (pennzoil, quaker state etc) actually included it in their name.
