2025 yukon denali, 2019 nissan maxima that gets driven pretty hard.

Mobil1 0W40 FS
Pennzoil Platinum Euro 5W40
Castrol Edge 0W30/0W40
Quaker State Euro 5W40 (repackaged PPE 5W40)
Motul X-Cess 5W40 GEN2
Valvoline European Vehicle 5W40

Thanks. So what is the spec in the euro blend that makes them better than a dexos 1/r?

Mercedes Benz 229.5, BMW LL-01, VW/Audi 502 00/505 00

If the oil meets any (preferably all) of those three, you've found a winner over dexos.

They have more robust additive packages (both anti-wear and detergents/dispersants, they typically have higher HS/TS ratings (which in turn leads to better base stocks), and they're if they're packing those certs, they've been rigorously tested by the OEMs to ensure suitability.

And if it also meets Porsche A40 you can't get much better.
 
I'd put something like Quaker State Synthetic up against any Euro spec any day for a GM engine.

Stick to the specs unless you find for sure otherwise. Manufacturers make a spec for their engines. It's not global. Euro isn't better than Dex. Dex isn't better than Euro. Within the application there is a difference.
 
@edyvw listed bunch of good ones.

I just bought couple of jugs of Castrol Edge Euro 5W/40 on sale for $23.97 / 5 qt.

They were out of 0W-40. Not that I care since Kirkland would do the job and this is already overkill for my applications.

Castrol Edge Euro 5W/40 approvals:
API SP,
A3/B4,
BMW LL-01,
VW 502 00 / 505 00,
Porsche A40,
MB 229.5,
and 2 Renault xyz.
Also recommended for:
3 other Fiat xyz and
3 other Chrysler xyz.

I think it might be tough to beat these approvals! Especially for the price.
Usually when they do that, M1 Euro 0/5W-40 goes on sale next and I grab couple more and somehow manage to lose them in the garage. I recently found 2 jugs of Castrol Edge Euro 0W-40 API SN I purchased in 2020. ;)

I would put Castrol Euro 5w30 up against any off the shelf full syn 5w30 on the market. Stout add pack/TBN and 11.9CST@100

Why? Castrol makes a Dex oil. You can't just go by the numbers such as TBN. Otherwise, you'd go to the store and all they'd have on the shelf is 'oil' because someone figured out the best global oil. All it took was pumping the addpack to max. Weird nobody figured that out this whole time. Seems naive to think about lubrication properties when framed like that doesn't it?

I get the impression that people think running Euro oil is some sort of cheat code for maximum super engine protection. As if the oil type specified by domestic automakers is part of some planned obsolescence conspiracy. Yet, the list of most reliable cars on both Edmunds and Consumer Reports is consistently pretty short of European cars. Hmmm gee. Putting European cars and European oil on a pedestal isn't correct.

OEM's test lubrication properties for specific engines to a far higher degree than you or I could possibly do. ASTM tests, but how do you choose what's good within each category for which engine?

QS 5w-30 Synthetic protects way better than Mobil 0w-40 Euro FS in my GM engine. Better oil pressure as temps climb, less evaporative loss, far fewer filings on the plug magnet. Went through 3 changes on the Euro btw. Pretty consistent results. QS showed improvement on the very first. That doesn't mean I'd call it a better oil period and feel comfortable putting it in a BMW.

Meet the spec. Plenty of options for each. TBN and such...moh isn't necessarily bettah.

I think for an average driver with no crazy RPM (i.e. the majority), it's all about OCI. And Euro this or that wouldn't matter much.

Given the choice, I rather use a regular Syn like ST, Kirkland, Havoline, etc. for 5K OCIs than extend it with a fancy Euro to 10K OCI. They all meet my car spec. But I see Euro on sale for $3 more (per 5 qt.) and can't resist so lately I have been switching back & forth. It's all bout OCI baby. Keep it clean! :ROFLMAO:

Waiting for M1 ESP 0/5-W-30 to get into the $23 range. I prefer narrow(er) spread oil like 0W-30 over 0W-40.
 
The bar is set pretty low for API resource conserving standards. Even Dexos 1 Gen 3(arguably the most stringent domestic) has approved syn blends. Chrysler MS 6395 even has approved conventional oils.


One euro example 504/507 has to pass 3 phases. First being 1397 hours, second 1402 hours, and finally the Baumusterprufung program with a minimum of 10,000 hours. Many include track testing. Emphasis is set on wear protection, engine and piston cleanliness, oxidative thickening, shear stability etc. High quality additives and base oils are a must. That’s why these approvals are sought after.

How does it protect better. I am all ears about methodology and data!
