Aramco is the Saudia Arabia Royal Family. The Valvoline oil change stations are separate, still USA owned. Valvoline still has offices and a refinery in Kentucky amongst other places, but they are now owned by Saudia Arabia, including their offices and refineries in the United States.
Castrol vs Valvoline

Aramco owning Valvoline provides them with amazing resources they didn’t have before. Valvoline Restore and Protect is an example of those resources. Additives are being developed in labs and universities in Mumbai per Valvolines LSJR vid. They are also adding more GTL to some products.
I’ll tell you that Castrol EDGE Extended Performance carries some impressive approvals and I look forward to some here using it.

We have TWO Toyota plants where I live. One was their V8 production facility and the other is in partnership with Kia I believe. They employ a LOT of folks here and they are treated well from what I’ve been told.
Are those the ACEA and MB 229.71 (0W-20) you're referring to? Your comment prompted me to Google it. Thanks for calling my attention to it. Was not aware this "non-Euro" oil had Euro approvals.
I'm curious how much more stringent 229.51 or .52 is over ACEA A5/B5, C2.

Is Castrol EDGE Extended Performance a non Euro oil? I thought it was a Euro oil. Maybe I just thought that because it's Euro approved. Either way, same end result isn't it?

Castrol EDGE Extended Performance & Valvoline Extended Protection are both very good oils, IMO. Valvoline has slightly higher cSt per grade, if that matters to you. Otherwise I suggest whichever costs less because you won't go wrong with either.
If you want more tech data, I suggest comparing their data sheets (download from their websites) and compare VOAs & used oil analysis which you can find at BITOG.

Its HTHS is less than 3.5 so I wouldn’t consider it one. There is a Castrol Edge Euro.
All right so I looked into this a bit, and I'm not really seeing any benefit of Castrol EDGE Extended Performance over a quality, OTS Euro synthetic like Mobil 1 ESP. More approvals and higher HTHS. Maybe I'm missing something, but I'm not seeing the draw.
good advice - this is how i pick my beer and my engine is fine!

I tried Castrol in my truck a few yrs back and, it used a quart between oil changes. I then went to
Valvoline and the oil consumption stopped. Don't have any clue why but, it did.
However, back in the 1970s when I got my first vehicle, and the next few vehicles afterward, I used
Castrol with no problems whatsoever. I'm not sure why it didn't work well in my newest truck and
Valvoline did. Back then though, all I was using was conventional oil, (Havoline), and both were synthetic
when I tried them in my newer truck.
I do now use the Havoline, again, in my truck. The Pro DS 5W20 and the truck doesn't use any between oil changes.
It stumps me although, I am by no means an oil expert.

My Accord burns significantly more Castrol Edge High Mileage than Mobil 1 Extended Performance High Mileage, both in 5w30. It also burned a lot more GTX High Mileage 5w30 than Pennzoil blend High Mileage 5w30.
A5/B5 A7/B7 are euro 0/5w30s with HTHS < 3.5.
They are nice looking.
Fact: We’re living in a global economy.
I am doing this for my Kia GDI. Book says A5 which Castrol EDGE Extended Performance meets, but GDI needs the ring cleaning of Valvoline Restore and Protect.
Smart
The thing that you're missing is that Castrol EDGE Extended Performance 0W-20 and 5W-20 are ACEA C5 oils (HTHS b/w 2.6 and 2.9 cP). Castrol EDGE Extended Performance 5W-30 is ACEA C2 (min. HTHS of 2.9 cP).
Mobil ESP 0W-20 is ACEA C5. Mobil ESP 0W-30 is ACEA C3 (min. HTHS of 3.5 cP).
That's the difference b/w Castrol and Mobil in this case.
Good point. I forgot that Castrol EDGE Extended Performance 0W-20 is MB 229.71. I would never use 0W-20 so I forget some of the approvals on that grade.
