Kind of asleep at the wheel I think ZDDP has been severely cut from newer oils even the diesel oils. Newer oils must have less than 800ppm to get the american petroleum institute current S ratings. Gee i have some old CANS of oil on display in my garage, maybe SF or SC. Maybe that's the best oil for my volvo now.

Hi,

I have to say that you are probably worrying about a bunch of nothing.

For several years now the petroleum industry has been lowering the amount of that stuff in oil.
Engine failures have not been an issue or you would be hearing a great big roar of outrage.

If you had been looking at the symbols on all oils they have been showing us that the oil is being revised to meet the manufacturers requirements.
They use to be SF back in the seventies and slowly progressing through the alphabet.
The latest is SN, of which, I can say in my mind is that they have finally went to labeling it correctly.
The “N” which means “None” is in there.

With each change up through the alphabet the response to that change the petroleum institute is trying to find ingredients to make oils meet or exceed certain requirements and most of all they have not put any disclaimers that the oil is not backwards compatible for its intended service.
It’s a “Joe” consumer quality assurance thing but more importantly an industrial one.
Airliners, Fleets and Earthmovers, ect.
We’re talking big time equipment costs if standards are not provided.

The big deal here is where the oil in service. Diesels requirements are different as well with their viscosities. You don’t see zero weight oil for them.
With the latter word in the former sentence being a factor.
There has been an energy savings kick playing out towards consumers, especially those with NASCAR propaganda advertisements tingling inside their brains.
Are you a NASCAR fan and a cruiser of the additives aisle?
I suggest you leave oils alone.
You could get more savings by not running your headlights in the brightness of daytime! IMHO.
There are so many people trying to blame their accidents or actions on I didn’t see the vehicle coming!
Before you know it they drive only looking for bright lights.
Probably good for motorcycles up to a point, but you can still will get bit by a mosquito because you were looking for fireflies. (:-) Bites come in many different ways. (:-(

So with that, there are snake oil people out there looking gimmicks to sell.
There was a problem with yesterday’s oils. Chemistry has come a long ways and ZDDP was the answer for the times.
The Lubrizol Corporation, a Berkshire Hathaway company, is a market-driven global company serving customers in more than 100 countries. The NYSE is not normally always good for America or the world over profits.

Yep, about .3 to 1% as an additive was advertised in Pennzoil. Never saw any difference.
I have never been fond of that or the Quaker State brand either.
Especially after the latter got sued for lots of engines being damaged back in my days.
They really did good hiding that fact. Some still remember and I can still speculate with suspicions.
There is now top and bottom tier gasolines, so, why not oils.
The API does a great job of holding the line of standards made and that licensing symbol.
If it doesn’t have a API symbol you might want to back away.
The Europeans have very similar standards to fight off what surrounds them over there too.
Imagine no distant watery shores between the cultures but then China and Asia is everywhere with the knockoffs not being a new idea either?

Before API, I remember as a kid, adding quarts of bulk oil from glass jugs into peoples engines.
I filled from a 55 gallon drum kept in a back room.
Other quarts came in cans that required a pushed in oil spout. I still have one of those, but no cans whatsoever!
Gone the way of ZDDP I reckon?
My advice,
Be aware of any holy grails of anything.
Now I’m back to my first sentence.

Phil - I had a '56 Ford station wagon that lost so much oil that I got a couple of quarts of oil drained from cans and a couple of GALLONS of oil drained from cars every week at my local garage.

Eventually the engine blew up and when I took the head off I found a large hole in one piston and a carburetor bolt in the crankcase that had blown off the bottom when raw gas finally got ignited by the broken plug in the bad cylinder.

I found out later that my buddy's father had lost a bolt when he rebuilt the carb, he thought that it was on the ground somewhere.

I drove this $5 car for 6 months or so.It was a top of the line wagon that my friend's father had repainted, including the wood grain and molding on the sided and back. He sold it tome because it ran poorly.

AH - the good old days!

Hi,

You must be talking back quite a ways. They haven’t put motor oil in metal or cardboard cans since the early eighties at best. I still have a punch in spout.
I use it now to push down the toilet paper roll for my Frantz oil filter canister. I have three cars fitted with them going back to 1974 when they were reasonably popular.

Now how that for talking about the old days.
Good days are according the molecule of cream you are floating on in a tall glass of milk. Some are higher or lower in the same glass.
Even though, the curdled seem to lump up and spoil the whole glass.

A $5 car is unheard of.
That was a project bargain to get into. Today, they say, you haul you get it.
In what year did all of this take place? That bought the owner a couple six packs of cheap beer.

Maybe he was rebuilding the carburetor while still bolted onto the engine?
If it was screw and not a mounting nut.
Fords used studs and nuts.
You would think a small screw would have gotten out by the exhaust valve. But then a nut, that’s another story.
The piston and combustion chamber must have been peppered with dings.
Yep, the spark plug tip probably got smashed.

A hole in a piston is usually from lean burning and bad timing. Also a very hot of heat range on the spark plug being used. In the likelihood of trying to burn off excessive oil and keep the plug cleaner.

Premature Detonation can be confused with a nut knocking around in the engine too.
6 months of running that way was purely fortuitous.

You are correct about bolt vs nut - it was a nut.

This took place in 1965.

I bought several cars from best friend's father - he worked as a body man at a Pontiac dealer - he bought several cars foe 5 or 10 dollars before they went to the auction. He once took a 54 Ford and cut the entire body off with an axe and a small sledge hammer, The only stuff left was the bumpers, radiator bulkhead, floor, front seat and firewall. He used it as a tractor to haul firewood.

I actually cut apart a 26 foot travel trailer that (was stripped out by a car lot owner) with an axe and a small sledge hammer and put the pieces in a dumpster that was in my yard for a roofing project. A guy named Scrappy John took the aluminum skin, window metal, frame, and axles.

An anecdote - I was taking a new girl to see Goldfinger when the engine went POW and smoke came out of the grille and front fender wells - she asked - what shall we do? I replied - Hide behind this tree and watch. Needless to say, the date was busted.

SKU: 9207830 Other Names: Valve Tappet Description:

C70, S70, V70. 850. 960. All models. S80.

Even for newer models. Like s80. Drop in zinc might be bad, some say newer cars either went with roller tappets or lower valve spring rates. Cams could be in danger.
