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..
