what u think about pennzoil?

[Ranger Dave (B25)]

EVERYONE hates it. youll be hard pressed to find a quarter of the people that chime in liking it unless the people on the hate side dont comment

What?

Pennzoil is what I use in 3 of my 4 vehicles, damn near exclusively. The other (JettaGLX) I run Castrol full-synth because I run it VERY hard when I drive it.

And for the record, 2 of the aforementioned have a cumulative half-million miles on them. The other is only 3 years old with about 26k. And the Jetta I sold 2 years ago had over 300k on it, used NO oil, made NO noise and I used Pennzoil in it the whole time I owned it.

If it was that bad, I'd know it LONG before now.

EDIT: also for the record: the only oil I've had MAJOR problems with is Quaker State, which IMAO is the shittiest oil God ever inflicted upon man. I got tired of pulling the heads on my 351C in another car (yes, I are a Ford gearhead from way back) and having to literally scrape an inch of coked-up sludge out of them every 25k before I could send them out to be reworked (sludge causes terrific heat problems in cast-iron V8 heads). After 3 times, I said screw that, and went to Pennzoil. No other mods, just changed the oil brand.

No more problems.

yo man pennzoil is crap man, ou can get wal-marts brand oil I think is made by valvoline or pennzoil not sure just doesnt have that name on it look for generic oils and on the back youll see who the manufacturer is for that generic brand, the only diff is you aint paying the price for the name.

im not in the Us so walmart....

why u say its crap? u had bad results using it?

 

[TheTopher]

I REFUSE to put penzzoil in my truck as it's cheap honduran crap oil. Just kidding, mate.


Personally I've never run anything but mobil1 in my vehicles since I got my license...why change a winning formula? If I was ever in a pinch though, after reading this thread I may not mind penzoil too much.

I used penzoil & ford oil filter in my old 88 2.3 Ranger from 89 to 99 and never had any problems with it ever. I even went 4,000-5,500 miles between oil changes due to driving across country numerous times.

When I bought my 94 3.0 new in 94 I have only used Ford oil and Ford filters on it.

I have seen alot of build ups in the heads from penzoil, but I believe any oil will do that if not changed often.

Like my old friend from high school in 89 he got a brand new 89 2.3 Ranger and he went 40,000 miles before he did an oil change, he just added whenever the light came. Don't do that.

no i would never do that. hell my 99 is resting a long nap cuz the oil has around 4k miles too. and i dont want to drive it anymore like that.

my toyota had a lot fo sludge when we teared down the engine and it only had around 50k miles.
so yeah any old oil would do that. that poor car didnt had any maintenace from the prev owner.

I use castrol in everything, so I don't have much to say about Penzoil.

Ditto, either that, or some off-brand stuff that a store sells here. (good stuff, same company I think, as Castrol).

Been using it since dad worked NASCAR back in California.
Now, I need to drain the truck and replace it, dad put Penzoil in it...... It runs horribly! the engine sounds worse as it gets lower =P.
(and we had that oil in it for the 2 months we used it).

 

[wahlstrom1]

I've used pennzoil in every oil change I've done on the 5-6 vehicles I service regularly and I've never had an issue. Where I purchase it, it's usually $2-3 a jug (4.4L/1G) cheaper. Only thing I've ever heard bad about it is if you have a leaker engine it'll make it worse then other oil brands, but I have yet to have a leak except for valve cover's....which leak from factory!

How does a rebuilder know what was used in the engine? They buy cores. the oilo molecules don't have little yellow stickers on them.

Do what you want. If you are going to vent on something it's much better (historically speaking) to vent on a brand name than to vent on a race, color or creed.

And don't change your oile every 3,000. 7,500 is the modern standard. I do it every 6 months except my old indirect-injection motor requires it at 2,500 if used for towing, which it is.

yes I have it has created sludge build up in every single engine i have torn apart myself it leaves burnt deposits inside your engine wich will in turn start to clog it up, but that mostly depends on the driver, the reason I say its crap when I hear an ACUALL chemical engineer telling me about how its refiined and one of the chemicals used in the filtering of it is H2o wich is water. it is an ok coventional oil but like a lot of ppl say it better to run bs oil than to run none at all, I am extremely hard on my vehicless I build them to run them into the ground just to rebuild them back up again till I cant do it any more and my main thing I try to protect is my engine I use royal purple or amsoil wich is very exspensive racing oil I know it wont break down on me, pennzoil and quaker state both will. its where the oil looses its viscosity and starts to burn an turn black then leaving behind that black sludge build up. and the way I drive I will have to change around 1000-1500 miles wereas the oil I use I can run hard all day and and still change my oil at 3000 miles and its comes out almost as clear as it was when I put it in. watch you oil as you drain it the darker it is the more burnt up it is.

thats easy most customers acually know what oil it is they use and tells them but thats not always the case cause there are instances where daddy changed it for one of their kids, but then you also have the oil change and lube places where most of them acually place a sticker with the weight,brand and type of oil with the mile age and the date of the change so when something goes wrong and it is in the shop most mechanics will that, and for the most part replace with the exact same oil.
irregardless if we like that brand or not its the customers choice.

well i dont abuse the trucks, just the ocasional 5-6k rpm shifts lol.
didnt knew that oils could be replaced at 7.5k miles now. im gonna check the pennzoil bottle tag.

walmart canada runs penzoil in the oil change shop big barrels of it. i worked there and didnt have anyone complaining about the oil/

 

[Mafusa]

like I said earlier it all depends on the drivers pennzoil is an ok conventional oil but I wont use it because I dont use any oil that uses H2O during processing it from crude down to what we buy at the stores , not all of them use the same process to refine some use a petroleum base to refine it wich is acually what makes those brands more expensive. if you can ask a chemical engineer/ engineering consultant that acually designs and builds the rigs and pants for them they can explain to you all about how the crude oil is broke down, doesnt mean not to use it if you drive an engine as hard as I do you dont want to use a conventional oil you will burn that oil up, all it really does is leaves a build up behind inside your engine, but so will all oils if used to long I have just seen it more so with pennzoil. if an engine gets burned up or blown isnt cause of the oil its cause 1 it doesnt have any in it.or 2 cause the owner didnt change it like they should have.

the bad thing about Pennzoil it has a high perfortane(?)cant remember if that what it its call, basically a high wax concentration that creates sludge, any engine ive torn down that has ran a lot of Pennzoil has had a lot of sludge in it, and talk to any engine rebuilder out there and they will say the same thing

Only a matter of time before someone mentions that Pennzoil has "paraffin wax" in it.

Most conventional oils today are paraffin based, this is not candle wax. as some people like to think.

The word paraffin is a very common and basic term for base mineral oil. The MSDS sheets for many motor oils use the word paraffin to describe the main oil ingredient...as in "SOLVENT-DEWAXED HEAVY PARAFFINIC PETROLEUM," which is how Valvoline phrases it in their MSDS sheets.

Paraffin is the proper organic chemistry word for aliphatic hydrocarbons...more commonly known as oil. It is also the correct name for wax and candles. But there is as much difference between paraffin wax and paraffin oil as there is between a chestnut horse and a horse chestnut. They just aint the same thing. Don't matter whether you're talking about Pennzoil, Castrol, Valvoline or your wife's Christmas candles.

In short, just about ALL conventional oils have...gasp...paraffin in them!

If you're still changing oil at 3k miles, you're still living in the 1970s. Even the CHEAPEST conventional oil can go 5k miles easily.

The 3k/3 months continues to get pushed just to sell oil. There are few, if any, cars out there any more that actually need 3/3 (malfunctions excepted). By the reasoning that is most often offered in support of the 3/3 (you may not really need it, but your engine will be nice and clean, or alternatively my favorite: "cheap insurance ") why don't you just go ahead and change your oil every week. Or every day perhaps. In virtually all cases today, the oil is performing as well at 3k or 3m as it was when it had 1/1, or less.

The fact that seems left out of these discussions is that since the time when 3/3 probably made sense (at least 30 years ago), nearly all the factors that drove that need have improved.

=====>> We've gone from carburetors that left our primitive engines' primitive oil awash in surplus primitive gasoline, to very precise fuel injection. Cars with fuel dilution are now viewed as troublesome exceptions to the norm.

=====>> We've lost the lead in our fuel, which used to leave a massive mess in an engine's oil.

=====>> Crankcase ventilation systems have advanced lightyears ahead of what we used to have, leaving our oil much cleaner and drier than it used to be.

=====>> Our engines are now programmed to warm themselves much more quickly and effectively than they did before (making short tripping less dangerous than it used to be).

=====>> Ignition systems are now much more powerful and precise, contributing to much cleaner burning than we ever had before.

=====>> And then there are filters -- much better too at cleaning than in the past.

=====>> And finally, then there's the oil itself, which is so much better now than it was before that it's amazing, and this would apply to both syns and dinos (most of which are now about as good as a syn anyway).

When you consider that virtually EVERY factor that used to weigh heavily in favor of the short 3/3 has changed hugely in our favor, it seems nearly laughable that oil companies and quick lube chains are still pushing 3/3 with a straight face.

well its more a instinctive thing on me- replacing it at 3k.
i dont spend that much, and sometimes i go over 3k, like this case im on 4k on the same oil on both trucks.

hell in my first car i changed it every 2.5k and i used motul oil- i was young and i loved that car, so i thought i was doing good.

so basically penzzoil is as good as every other regular oil?
