Pennzoil joins the 20k mile club?

[BrendanC]

20k mile OTS oil gets run for 6K in my book. i drain HPL oil at 12k.

I think it increases sale because people will not dare do 20k miles intervals. But Oil geeks like BITOGer may buy it, trying it, and yet still do 10 or 5k miles OCI with oil that may hold 20k miles.

I also use ACEA C5/C6 Oil on my Toyota, most of these C6 oil are considered to be a longlife oil, and 20k miles is possible. I still change mine every 5-8k miles, just because I chose economical oil that has trully approval from either VW or C6 spec. Unfortunately, ACEA does not do certification, just stating what the spec is.
Usually only Diesel car owners with 7L+ oil sump do 2y/20k miles interval in Europe. Most of them also mainly travel on the highway. The catalytic converter and DPF may fail first before the engine.

Yep, sooner do 10k with an EP than extending it on my own …
Anything longer would have to be boutique …

Regular PP can't make it 6,500mi or 10,000 units of communism in my wife's car before the viscosity breaks down. Last oil test I sent in they thought I used a 20wt oil, I know I put PP 5w-30 in there. I haven't bought any brand of 20wt oil in probably 3 years. Only 20wt oil I buy is 20w-50.

Breaking down due to mechanical shear of the VM? Or was there fuel dilution?

I can say with absolute certainty the oil had 5,700mi on it. They claimed 8.6cSt and less than 2% fuel. But I also put in nearly a quart of 20w-50 makeup oil.
I get similar results if it's a 1/2% fuel.
I'm running PP 10w-30 this time.

They being Blackstone? My point being that if it is fuel dilution (which it likely is) then Pennzoil wasn't the problem.

Thats the darn thing. You can CLAIM 10k oil 20k oil 30k oil gazillion gajillin petaflop miles.
If your modern DI engine turns your oil into 2 stroke fuel in 8,000 miles the oil rating is irrelevant.

Other oil tests I've sent them are as expected. It's just this car.

This!

That's the reason why i follow the maintenance minder with the Civic (old, proven K24 and almost no oil dilution) and why i run 0w20, not 0w16, and absolutely wont go to the recomended 16k km ever with the Prius. An absolute fuel dilution monster.. Might even try 5w30 during summer..

The average age of cars in the USA has now reached 12 years …
There are still some non GDI motors out there like the Pentastar …
Seems there are a fair number of dual point injection motors that allow for 9k/10k changes … Tig has done 10k for decades …
It comes down to good recommendations - and who here ever saw an oil change place - or OEM try to push 20k ? … IMO, It’s a solid pick for 10k in the right motor - and the cost does not give rise to go longer (like a boutique) …
See post #13 …

Even if you don’t want to push your oil to 20k it’s nice to know that the oil has what it takes to go a bit longer than others.
For instance, if you want to be doing 10k intervals would you rather use an oil that’s rated for 10k or one that’s rated for 20k?

That is a good point. But as a person doing 5k OCI, I would prefer 10k interval oil over a 20k interval oil. My reasoning would be that, to make it last longer, they probably had to trade off some things that would be more beneficial in the shorter intervals. Perhaps increased the detergents while decreasing the moly, etc.

 

[Faawrenchbndr]

Nope……not this guy.
My driving routine always puts me in a severe service 5k OCI.

 

[fantastic]

Not PUP but I ran another brands oil that claims "10,000 Miles Guaranteed" for 11,038 miles with no issues.

SOPUS/Shell, the parent company of Quaker State and Pennzoil have been selling 20k miles Oil spec for decades in Europe. VW/Audi/Porsche also outsource Shell as their OEM supplier for its Longlife 20k/2 years engine oil. I think most european standard ACEA oil are Longlife with 20k miles service.

Ferrari does that too. It used to be Shell everywhere. Now it is Pennzoil in the USA, Shell in EU.

 

[rondhol]

Well, if Ferrari uses GTL oil, we know it is a serious deal. In facts, I plan to switch to 10k miles interval if using GTL. Chemically, GTL resembles HC synthetic group III oil more than PAO. PAO is still more stable, but cost much more. For 10k miles interval, I think GTL is more than enough. It has much more homogenous molecular size than HC synth.

Twice a year. Close enough.
