Pennzoil Z-7 score!

[54Illinois]

I scored 1-1/2 cases of mid 90's Pennzoil from a basement...free.   Like new condiditon, gonna add a quart to every oil change to bump up some zinc.

 

Anyone know how much zinc per quart?  I would think at least 1000ppm.

 

Either way, free oil is good these days!

 

[Plymouthy Adams]

are you breaking in a new engine every week?

[54Illinois]

LOL....no, I am going to add a quart to the cheapo oil when I change it. 

 

I may just use it in my 1991 Chevy 4.3 P/U truck, that gets driven more!

[Grdpa's 50 Dodge]

wonder when the old formula penz was changed to the new formula??

 

Reason I ask is I bought a brand new 75 Granada with a 6 banger which was a decent car in the day,one of a very small number of new cars purchased.  Reason it died was using Penz oil from brand new.  Ads all said it was fine but it gunked engine terrible and mechanic said no hope unless complete overhaul and it barely had 100k on it PVC couldnt keep up with it

 

Needless to say I wont put penz anything in anything I owned,,,If I had some you could have all mine too!!  Lots of good oils out there but penz isnt one of them in my book.  I could probably start a fire with it, my luck it wont burn.

If your lucky sometimes at your local recycle centers they might have a shead set up so you can browse around inside and pick up oil that was discarded by it previous owners in new containers.   I have gotten everything from Antifeeze to all kinds of oil additives.  But its not a sure thing that when you go to these centers they will have what your looking for but sometimes it does happen.  By containers I mean the container the product the material came in unopened.  I painted the whole backside of my house with paint that I secured from this place also.

WOW,

That's the definition of a real recyler!!

It's good that all Granada's are dead. They never were a very good car.

I have used Penzoil in my 51 plymouth since I rebuilt the engine in 1968.The engine still runs good and is sludge free because of regular oil changes. Just sayin!

[Plymouthy Adams]

Granada...they were never a top line car but if I had a chance to find a nice solid Granada two door with factory 302 and C4...I think I would seriously entertain getting it...with the right set of wheels and good paint job void of most trim...I like them....looks better than any Camaro or early Mustang   it has been years since I have seen a Monarch or Granada...I remember the dealership I worked at got in a load of Monarch with the Monarch name on one side and Granada on the other

Good possibility that the oil you buy today has more zinc than the mid 90's Pennzoil

[Dodgeb4ya]

I can still remember the weird smell of the vinyl upholstry used in some of those Fairmont and granada cars. As for the 302's used in them they had a double hump oil pan sump and the oil pan drain plug was only on one of the sumps! When I changed oil in them (Penzoil of course) I always wondered what the idea of a double sump with one drain plug. You could only drain 2/3rds of the oil. Really stupid. I had to replace a 302 in a Fairmont once too. A tough one to do because of that oil pan.The engine rattled and was full of sludge. Glad it's long gone.

[Plymouthy Adams]

I was gone from the dealership prior to the Fairmonts...moved on to General Dynamics for a bit then decided my future would be best going civil service in electronics...the dealership had given the parts manager a Granada Ghia with ALL the bells and whistles w/302 V8..drove that vehicle a number of times...

When I was a Ford salesman for a time in the mid-1980's, my customer traded-in a '75 Granada with ridiculously low miles.  I bought the car for my then-girlfriend and she drove it for a few years.  The car was very nice but had manual steering and it was like driving a  truck.  After we broke up, she overheated the engine and it went to the junkyard, but the junkman told me it was too nice to scrap and he sold it to a kid who fixed it and used it.

I have heard that the Pennzoil had the parafin wax added, and that is what would gunk up the motors.  Then I have heard the opposite...

 

 

Either way...Free oil is a good thing!

[Plymouthy Adams]

Pennsylvania grade crude is paraffin based (Quaker state/Penzoil) none is added...gulf grade crude is tar based..Valvoline, Havoline etc etc

Yup, different dinosaurs.

I believe that was true when most motor oil was simply distilled from crude. Is that still true today? Seems like they have a lot more things they can do at the refinery to get whatever mix of products they want from the crude oil.

[Plymouthy Adams]

not sure of the distilling process to X product but crude base would be crude base whatever the end product would be in my opinion..you got to start from somewhere and if dino..those were the two choice as I understood it...growing up in the moutains of eastern US..I am very used to the sweet crude straight out of the ground..very pretty green tint to the liquid...and an odor very pleasing to the nostrils..paraffin based...

I am using Lucas hot rod/classic 10w-30 oil in my wagon. In their ads it states NOT to use oils with high zinc in any cars with a catalytic converter . So using it in your truck would not be a good idea.

[54Illinois]

Does the 1991 Checy Cheyanne even have a converter?  I would have to look.

I would guess it does. My 1977 Pontiac Grand Safari station wagon (best car I ever owned) had one that I eventually cut off in the days when you could easily do that.

All cars from 1975 had catalytic converters. Another reason lead was taken out of gasoline. In some states that have inspections, the catalytic converter must be on the car or it will fail the state inspection.

Yes they came out in 1975. In the early days some of the trucks above a certain capacity were exempt but I think by 91 that was history.

This thread makes me curious whether or not motor oil breaks down over time - ?  I don't know the answer, never thought about it since I never have motor oil sitting around very long, but manufacturers recommend changing oil based on mileage or time, whichever comes first.  Light machine oils don't, so maybe motor oil doesn't either?

[Plymouthy Adams]

property of oil does not break down unless seriously fried they only get filthy with contaminants and lose their detergents..
