I PUP isn't an extended drain oil. [/QUOTE] I went 17+k miles on PUP 0w20 with barely over 1ppm/1k mi (18ppm in 17 said:135375[/ATTACH]
I don't have a reference for this. TBN used to be reported for virgin PUP in the past I believe and was lower than virgin TBN for previous iterations of M1 EP at the time. Don't know about how they are now.I went 17+k miles on PUP 0w20 with barely over 1ppm/1k mi (18ppm in 17,150 miles) and still had 2.9 TBN left… where do you get that PUP isn’t an extended drain oil?
It looks like you had an intake tract leak (or K&N?) that lead to high silicon, and an oil cooler on an engine that was still breaking in. The oil itself was still in grade and still had active TBN left, flashpoint is great; there’s nothing concerning to say the oil was overwhelmed. That engine was still only making 2ppm/1k mi Fe which is no problem at all.It seems that my previous car was harder on PUP than yours. Here's my one and only UOA on my 2013 Ford Focus ST (2.0T GDI), 11,753 km OCI (13,093 km, odometer). TBN remaining was 2.4.
The fact that Pennzoil doesn't advertise and market it as an extended drain oil. If they did, it would be, but they don't, so it's not.I went 17+k miles on PUP 0w20 with barely over 1ppm/1k mi (18ppm in 17,150 miles) and still had 2.9 TBN left… where do you get that PUP isn’t an extended drain oil?

Aye.This is correct. While I'm sure it's more than capable of handling longer intervals in many applications, Pennzoil does not explicitly market it as an extended drain product like M1 EP and Castrol EP are.
You nailed it. I had a K&N. At the time, I remember deciding to keep it in because the iron numbers remained low.It looks like you had an intake tract leak (or K&N?) that lead to high silicon, and an oil cooler on an engine that was still breaking in.

Since at least the mid '80s, Pennzoil has refrained from claiming extended OCIs on PCMOs. When I started with Pennzoil Products Co. in 1985, a synthetic blend "P-Z-L Extended Life" oil had been recently discontinued.This is correct. While I'm sure it's more than capable of handling longer intervals in many applications, Pennzoil does not explicitly market it as an extended drain product like M1 EP and Castrol EP are.
My recent reading says that the Gen3 stuff has the SP rating and that both those designations indicate a reformulation specifically for cars like yours. They are supposed to have better protection against LSPI and produce less ash. My feeling is that since the car companies went all in on this boosted small engine craze that they are trying to make it less possible for car owners to put out of spec oil in cars/trucks that really require top of the line fluids.So I recently purchased a couple jugs of PUP and was clinging onto my years impressions of the pure-plus gas-to-liquids tech. Then after the fact, I became aware of the dexos certifications and how they apply to turbo direct-injected engines. And that the dexos1:gen3 certification is currently the most robust and protective for turbo direct-injected engines it seems.
My Hyundai Kona N-Line 1.6T manual just states a requirement for API SN Plus/SP or ILSAC GF-6 (which PUP 0w-20 already has). I think I know the answer already that both PUP and M1 EP are going to be "fine" and the engine is going to be just "fine". We all want the best for our engines of course. Notwithstanding, how much of a practical difference is one or other going to make over the course of two oil changes (each approx 8,000 to 10,000 km)? Is one or the other going to help reduce the rate of intake valve deposition? My car currently has 2,400 km. I did an early oil change with PUP 0w-20 at 2,200 km.
Just a bit bothered by not having carefully considering my oil options before I purchased the two PUP jugs for my new car, that's all.

I’ve come across contradictory information when shopping online for the big brands. Walmart showing PUP that was only SN rated and a pic that showed no Dexos cert. but then claimed it in the details. But then I when I looked on Pennzoil’s website yesterday it didn’t tell me anything about specs. ***? Could not clear it up. However, the plain platinum has SP and logos for Dexos Gen3 which I just confirmed on the jug. Why would platinum have and not PUP? Ugh.I'm in the Canadian website.

The only Pennzoil with Dexos certs is Standard Platinum.Both can be confirmed either on the dexos licensing page or the API EOLCS Directory.
If you're not looking for extended drain intervals, either one will work and you'll see a bigger difference in engine wear rates by keeping up with a paper engine air filter.
