Here ye, Here ye, Pennzoil causes sludge!

Posting twice in a row just to be #100 on this thread. WooHoo! Time to pull the valve cover and check for sludge.
 
My best friend's sister's brother's girlfriend's uncle, who was working on his great grandfather's uncle's wife's Fairmont, said when they opened up the engine last night, it was full of a waxy sludge buildup. The uncle's wife said he used nothing but Pennzoil.

I'll never use Pennzoil as a result of this information. My brother's friend's uncle's wife's internet lover says he uses Valvoline and his engine is clean.

I'm probably going to go with Valvoline. He also indicated that Fram filters are the way to go because they are $2 more than Purolator.

Pondering the exact opposite. Should I just lock it, or should I remove it to the unseen (by most of you) oblivion of the double-secret-probation "QP" sub-forum????????

In case any of you are wondering, that's the "Questionable Posts" place where we of the secret BITOG Skull-and-Bones club move, ummmm, well, QUESTIONABLE POSTS...

Just changed the oil in my Mom and Dad's 05 Town & Country, used Pennzoil 5w20 in the "yellow bottle of sludge" flavor...

I guess I should drain it out NOW and replace it before I get an oil pan of wax.....

Naaaaa, I think Ill do this....

I've used Pennzoil conventional in the past and switched to Platinum synthetic.I'm going back to the yellow bottle with full confidence that their oil(yellow bottle) does not cause sludge like some are led to believe.
(1)Best selling motor oil
(2)10yr/250,000 mile warrenty
If Pennzoil did cause sludge there would be lawsuits and a major investigation into Pennzoil oil.Shell/Sopus would not like that.I think pennzoil is now/or will be the factory fill for Chrysler cars/trucks.I have faith in the yellow bottle.Joe
 
Hi all. I am new here so please be easy on me.


I have a quick Pennzoil story regarding sludge. I had a 88 Ford Ranger that had 176,000 miles when the engine failed. I used Pennzoil and for every oil change since the truck was new. I did 5K changes and used Fram filters. When me mechanic pulled the valve cover the motor was full of sludge and my dad blamed the oil. My mechanic however realized that I had a thermostat that was stuck open and a clogged PCV valve. He told me that the sludge was caused by the lack of a new PCV valve and the bad thermostat. Currently, I have a 1997 Chevy c1500 with the 4.3 V6 and it was 170,000 miles with all Pennzoil. Now, I have learned to replace faulty parts on my vehicle. I had to replace the gasket on the one valve cover about a year ago and the valves were free of sludge. So I have no fear that Pennzoil is at least safe for my 4.3 V6.

As a result of all this Pennzoil conventional problems I decided its beneath me for now I will use Pennzoil Platinum as its a totally different animal

...that and I can still buy a jug for only $3 more than a jug of YB...yeehaw.

How can an oil be any good when it comes out of a yellow bottle? I noticed some of the yellow plastic had leached into the oil and turned it a different color. I know yellow oil when I see it and Pennzoil is yellow.

So that stuff you guys call wax is really just yellow plastic

I 'think' there were more problems with their 10W-50 grade, and the 'new' 195 degree thermostats that came out around 1980. I read in another thread about how the now hotter-running engines would really cook all the VII's required to make the 10w-50 spread....
 
Here is a question and point to ponder. If Pennzoil is truly junk and causes this waxy sludge buildup, how did Pennzoil Platinum ever pass the Honda/Acura HTO-06 test? Even Valvoline Synpower, as good as it is, couldn't pass the test.
 
It seems to me that if there was a problem with any motor oil involving sludge formation it would become obvious very soon-especially in the case of a motor oil that sells as well as Pennzoil. Mechnics who tear apart engines would soon notice the large amount of sludge in engines that had been using Pennzoil, or Valvoline, or Castrol, or whatever.

I think in the great majority of cases where an engine is sludged up if anybody really investigated there would likely be owner neglect. In addition there have been a few engines that for whatever reason were sludge prone.

You will hear people who say that Pennzoil has a lot of wax. As much wax as possible is removed from conventional motor oil.
