I'm new to all these specs and was just curious.
Dexos 1? All of them.I'm new to all these specs and was just curious.
So could you give a few specs and suggestions?Dexos 1? All of them.
R? Most of them.
Would be better if you provide the application and use case first.So could you give a few specs and suggestions?
2025 yukon denali, 2019 nissan maxima that gets driven pretty hard.
Thanks. So what is the spec in the euro blend that makes them better than a dexos 1/r?In the case of GM it could very well be a design issue, however it is also possible bumping up to a 40 grade could save them a ton of money in warranty claims. If that wasn't the case they would have never considered bumping up to a 40 grade, and bringing a lot of vehicles to do so. So imo there is something about viscosity playing a role in protecting an engine better than the CAFE thin oil push. Time to hide again.
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
etc, etc.
There are numerous topics around it here.
All the specs.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 00Thanks. So what is the spec in the euro blend that makes them better than a dexos 1/r?
And if it also meets Porsche A40 you can't get much better.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.
Anything with LL01, MB 229.5, and Porsche A40.So could you give a few specs and suggestions?
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@100I'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.
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 would put Castrol Euro 5w30 up against any off the shelf full syn 5w30 on the market.

Mobil1 5W30 FS is GTL/PAO based, available at AAP.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
How does it protect better. I am all ears about methodology and data!Why? Castrol makes a Dex oil. You can't just go by the numbers such as TBN.

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.
