oil related engine failure?

Was this Pennzoil or was it Quaker State? I do remember that in the early 80s, Quaker State put a lifetime warranty on engines that used Quaker State from the very first oil change and thereafter. There was an oil rep that came around to where I worked and explained the warranty and said they were having "gelling" problems. Never heard any more about it, but I do remember it was Quaker State. Pennzoil and QS were not owned by the same company back then, were they?


Yes, it was Quaker State and no they had nothing to do with each other back then. It was shortly after this that Pennzoil replaced Quaker State as the number one selling oil in North America. Until this happened, Quaker State had been the number one selling oil in North America for over 25 years. And as much as I hated Quaker State back then, I have to give them credit, they admitted full blame and bought every one of the engines it destroyed. It was somewhere between 1996 and 1998 when Pennzoil bought Quaker State.

Was the OEM cam also brand-new or had it been run previously? Just curious.

Johnny - about what year was this problem with QS?

Relatively few oil related failures (if the oil produced right), engine design, machining, break- in, maintenance, common sense appear to be far more crucial than brand of oil. Is the original poster making fun of us???? or at least a point.

.....But I like reading and talking about oil and other automotive fluids, so I will continue to substitute my own reality that this might actually matter.

As Tom NJ said, winter 80-81.

Oops missed that. Thanks.

Do Toyota's sludge-based failures count?

 

[oilyriser]

would that be an engine-related oil failure?

Not for this exercise. I'd put that in the design flaw category.

Hit the nail on the head. I think abot my next OCI, whether I'll run a UOA or not. My buddy's got 110,000 on an Avalon and never ever thinks about it. He runs conventional oil may go 7,500 miles may go 5,000 or it might just be whenever between oil changes. So yeah, I was poking a bit of fun, but curious too. I'm as bad as anyone here.

Well, I'm not sure, that's why I asked

I know that certain oils are more prone to developing sludge than others, and some oils have done exceptionally well in the sludge-prone engines, while others..... Well, they don't.

So I guess this would maybe be a "combination" situation.......

Depending on the year and the engine, some early Pinto motors had small tube with holes in it next to the cam. The tube simply "[censored]" oil on each camshaft lobe. Not saying that your maintenance was sub-par, but anybody want to take a guess what would happen to the cam when a hole plugged up? I've replaced a few of those cams and each one I replaced was from poor maintenance that plugged holes and ruined the cam.

Seriously, what a moron. Everyone knows if you snap your camshaft you have to pour glue into the crankcase to fix it, not oil!
