No love for Pennzoil....

Pennzoil has shown in my Toyota the best UOA over Mobil one, Mobil drive clean, Castrol Syntec, Castrol Blend and Castrol GTX.
Better than Syns or Blends.
Pennzoil Conventional 5w-30 UOA 4900 miles
When I can get great UOAs like this on well under a buck Pennzoil (with no adds, no special $$ filters) who needs anything else? (my best UOA on my truck has been with 49 cent Chevron)
I love $5 incl filter oil changes every 5k!
I do wish I had more Pennzoil in my stash...
Pennzoil is one of the best oils.
Period.
I don't sell it, I don't have Pennzoil stock.
Just have done the testing!
Dismissing facts on Pennzoil oil because of the parent company owning Slick 50 just cracks me up...
Take care, Bill

Undoubtedly 'cause of all the wax Pennzoil loads their oils up with that filled in the gap between the cylinder walls and what was left of the piston rings, huh? (Clever question of the day: How does a BITOGer feel when his favorite brand of motor oil is diss'd? Answer: "Piston". (OK, all you Bozos, I really was jerkin' everyone's chain - doubly so 'cause I intentionally chose not to put a cutesy cartoon "Graemlin" in at the end of my earlier post...

Bill, where are you getting PZ for $1??? I'd like to get in on that...maybe even persuaded to try it instead of the MC 5W-20 (perish the thought)!
I've got quite a bit that I bought when on sale for 59 and 69 cents a quart.
I've been using it up (down to about 80 quarts of Pennzoil) and still have Castrol GTX, Chevron and QS in the stash.
But, I will have to say that I do think that Pennzoil is a little above the rest.
But, with 4-5k OCis, any of it will take my engines to 300k with ease.
If I do find any more Pennzoil for sale below a buck, I will buy some more.
So far, nothing...
The MC your running is an excellent oil!
I go with whatever is cheapest for good product.
Take care, bill
In fleet service we replaced M1 5w-20 with Motorcraft 5w-20 with equal results at 5k intervals.
Opps, sorry, lets get back to Pennzoil. Does Pennzoil recommend using less Slick-50 with synthetic Pennzoil, that it does for conventiol Pennzoil?

"Dismissing facts on Pennzoil oil because of the parent company owning Slick 50 just cracks me up... "
Nobody has said that Pennzoil is a bad oil because Sopus makes Slick-50. Some, myself included, have said that we think less of the company because of it's Slick-50 piece of business and thus don't "feel the love", which was the original point of this thread. What is so crack up worthy ?
There are people who refuse to buy Castrol oils because they are upset about the definition of synthetic issue. I don't share their view, but I do understand it and can see why some people would make that a part of their purchase decisions.

So does pennsoil cause sludge do to the wax in the oil or is that just a myth.

Here it is; under the valve cover in my old Beretta in January of 2004, with around 310,000 miles on it at the time. Used Pennzoil exclusively since Day 1. No sludge.
I dunno, man, those valve springs look awfully dark to me..
I've never seen Slick50 packaged with Pennzoil OR Quaker State around here. The only association between SOPUS and Slick was some QS WITH Slick50 on sale at KMART or Wally World. In the oil, not a companion bottle of additive.
Dura Lube is still fairly prominant amongst the snake oils, but not Slick 50, at least around here at AZ and AA.
Definitely a crack worthy statement!
Slick 50 is similar to the many other engine oil additives on the market today , in that the performance gain for your $ is minimal or non-existent.
And it's a non-sequitor to try and connect the Slick 50 formulation of 10 years ago, during the PTFE ruckus & hoopla period, with the formulation that SOPUS is marketing today.
A quote from the XcelPlus website, a current supplier of PTFE engine oil additives:
Quote
We are the original Slick 50 formula," states Bill Smith, President/CEO of Xcelplus. "When a customer buys Slick 50 today, a brand owned by Shell Oil after they bought Pennzoil/Quakerstate, that consumer is not getting the original formula. They're getting a reverse-engineered formula that doesn't stand up to the original formula's research and scientific claims. If they want the original formula, with all the credible US Department of Energy claims to back it up, the formula that built the Slick 50 brand, they can find it in a bottle of Xcelplus. And only Xcelplus."

Pennzoil base oils come from the Shell/Motiva Port Arthur refinery, which is the largest GRPII/II+ refinery in the world.
This refinery runs the ExxonMobil catalyst technology that converts the wax hydrocarbon chains into Grp II paraffinic chains.
If the base oil produced from the Motiva refining process actually had a measurable wax content, then the ExxonMobil plant at Baytown, Texas and the Petro-Canada plant (Castrol) at Missauga, Ontario are producing "waxy" Grp II base oils also!
The whole "Pennzoil causes sludge" is a myth that just won't die.
I think it is silly, guilt by association, to imply Pennzoil is not a good oil just because Shell/Pennzoil/Quaker State still sells Slick 50. Johnny already explained how Shell, Pennzoil, and Quaker State all merged together and Slick 50 came with Quaker State. There was an attempt to sell the Slick 50 division and they could not find any buyers. The new Slick 50 apparently is not even the orginial formulation.
The engine picture shown above (an engine with more than 300,000 miles) clearly shows a pretty clean engine. An engine that used Pennzoil motor oil.
And another person had a post explaining how if the refineries used by Pennzoil produce waxy oil then so do refineries that make Exxon/Mobil oil and Castrol oil.
Enough said. As far as I am concerned the Pennzoil sludge myth is history. I was using Pennzoil a long time ago and I stopped because of this silly myth myself. This myth has become a widespread urban legend that will not die. Many urban legends are total nonsense and I am going to believe facts if I can, and not some silly nonsense.
What causes sludge buildup in engines? Probably usually poor maintenance-overextended oil change intervals, poor quality oil such as SA or SB rated oils, etc. And there have been some cases of sludge prone engines in various cars, vans, truck, and SUVs. The early Saturns were supposed to have had a sludge problem around rings according to some people.
If you are using conventional motor oil, whatever brand, CHANGE your oil often enough depending on mileage and or time. Synthetic oil may last longer but it needs to be changed at reasonable intervals also. Probable result-no major sludge buildup. You can use Auto-RX to help prevent and clean away sludge buildup. If you do own a sludge prone car or truck you will have to change oil very often and Auto-RX would most certainly be a good idea.
The Pennzoil sludge myth is dead for me. If somebody else wants to believe in silly nonsense like that then go right ahead. Believe in every urban myth nonsense story that you want to.

I've noticed one positive thing about this thread. It looks like almost everyone is now spelling PENNZOIL correctly.
SOPUS products make up a substantial portion of my stash. Between Formula Shell, Pennzoil Synth (SJ), Penz Platinum, Rotella T Synth, and SOPUS-sourced Supertech...
I have the SJ synth in my saab right now. It's from the Shreveport refinery before it was sold to Calumet....
Johnny, if you are still reading this, do you know why that refinery was dumped? I sure enjoy seeing SHVP on the production code...

Johnny, do you need a cyber-hug. Pennzoil is good oil and we really do understand that Slick-50 is just business to the exec's at SOPUS. Your participation in this forum is really needed to balance other postings. I think you have conducted yourself well in the barage of hollow jabs at the company you retired from. After buttering you up I have a question. Does Pennzoil allow their people to say that they are not involved with Slick-50 and have no recommendation one way or the other about the product, if that's the way they feel?
Of course if you are looking for reasons to not like Pennzoil then there is the fact that they own Jiffy Lube

I'm certainly not looking for reasons to hate them, in fact I am planning on switching both of my cars over to their oil within the next year! At this point it looks like my next oil change in the spring in the Corvette will be with PP, and next fall I am probably going to switch the Honda over to Pennzoil 5w30 (conventional).
Does it have a better percentage paraffinic base than other conventionals have?
