Does Conventional Pennzoil cause sludge?

no
Even if it did cause sludge at one time, and I dont think it was any particular oil in the day, oils from Pennsyvania crude were supposed to be the culprit, yet Kendall escaped the carnage somehow. Pennzoil is all new and under new ownership and reformulated. Todays Pennzoil is in name only, its a rebadged Shell brand oil. Shell being a major player and also owner of Quaker State, the evil sister, so said of the sludge makers, neither would even be remotely assoiated with the Pennsyvania crude oils of the past. Little note: Valvoline also started out as Pennsylvania crude, yet didnt get bashed.

NO
NO
we should have a sticky about pennzoil myths and facts. wanna see a picture of a pennzoil engine?
this car had its first 50k with the dreaded quakerstate! and the next 50k with "pennwax" and bout 10k with pennzoil platinum and then some formula shell and now its back on that sludge in a bottle quakerstate. all Sopus products its whole life and as you can see its completely sludged up

i guess everyone is entitled to their opinion.

The new API SN has practically elminated all sludge rumors for any oil. Go to the API website and read up on SN oils. SN = No sludge!
The truth is, any motor oil can cause sludge. Use an extra long OCI, make nothing but short trips (especially in cold weather), and add a little fuel dilution and coolant contamination. Bingo --- sludge.
The newer oils like SM/SN are less prone to sludge, but if you abuse the oil enough you'll have sludge formation.

Dang Old Cowboy, everything you comment on makes sense!
Your a pretty smart fellor.

Many years ago, someone posted pics of the internals of a GM 3100 V-6 that used nothing but Pensludg..........I mean Pennzoil conventional. This engine had the intake gaskets that leaked and everything, and with well over 300,000 miles, it was spotless inside! That was with the lower API grades of yesteryear.
Does Pennzoil or Quaker State cause sludge more than other dino based oils, no. However, any dino based oil (Grp 1, 2, 2+, 3) can sludge. The condition of the engine and use, oil grade for the operating condition, OCI, and the condition of the PCV system are few of the many variables that can cause an oil to sludge.
An employee that works for me has a 1.5 mile communte to work. His engine sludged because the engine never warmed up and he never changed the oil for over 20k miles. This would have happened with any dino based oil.

you know what really bumms me out is i have a friend in his 50s that tells me all the time how any old non detergent oil would be better than using pennzoil or quakerstate. EVEN AFTER I SHOWED HIM THE PICS OF MY WIFES ENGINE! (which is cleaner than his) he still insists PYB and QS are junk. i guess you cant argue with ignorance

People -- not just anti-PYB and anti-QS people, but ALL people, everywhere -- tend to believe things first, find reasons whenever they get around to it, and question themselves never.

No, and I proved it by feeding my DI, turbo, 116.5hp/L Speed3 a steady diet of it for 18,000 miles. It's a good oil if you change it according to your manufacturer's recommendations.

So...
Severe - 3,000 miles
Normal - 7,500 miles
Other* - 1,000 miles
* - if using Pennzoil or Quaker State, be sure to change your motor oil every 1,000 miles to avoid sludge-related engine problems

.... ONLY KIDDING!

In the 70's 80's PYB would turn to goo, I spooned lots of it out of many oil pans back then. Nowadays it is to top grade oil and I would use it in a second. Bad PR is a hard thing to make go away unless your a rock star, then any PR is good.
I had a friend the would not touch M1 to the day he died because it cost him several camshafts when it first came out. In latter years he know that they worked out the formulation, but it left such a bad taste he would not consider using it.
People tend to remember only the bad stuff...

Email from Shell when I asked if Pennzoil and Quakerstate were the same oil.
"Hello,
Our Pennzoil and Quaker State Motor Oils are not the same .They do share some of the additives . They are very close in comparison and compatibles.
Should you desire to speak with a technical representative to discuss this issue in more detail please call Pennzoil-Quaker State Technical Information at 1-800-237-8645.
