Would you consider Valvoline Restore and Protect in your Euro car?

Any 30 grade would meet the min HTHS required of 229.6.

From a HTHS perspective R&P would meet the min HTHS of the overwhelming majority of new euro cars.

Castrol has a 5w30 that meets MB 229.5 on shelves right now. All Valvoline needs is a 5w30 RNP formula that meets MB specs AND they could go get it licensed.

The Audi dealer did the oil changes on our Q7 before we purchased it at their 10,000 mile intervals, on time every time, even confirmed via an excellent CarFax reporting. We purchased it at 84,000 miles. They had just done another oil change service on it before we purchased it. we drove it 400 miles and it gobbled a quart of oil.

I asked the dealer what they used for their oil in their service department and they told me they use the Audi recommended Castrol Euro in a 5w40 flavor. Thats why I said I could care less about Euro specs, because this is the oil that stuck the oil control rings in the first place and coked them up in the pistons. So myself, I have no desire to use Castrol. I've used Mobil1 0-40 Euro in the past with great success in the Audis, but the CREC engine is know for its low tension oil control rings, but the fact remains it's the Castrol Euro that couldn't keep the rings and pistons clean enough. So really what good is the Euro spec right.

Exactly why I'm using the VR&P now, cause I don't care about using the Euro spec oil that did the carbon deposit damage to the Q7 in the first place.

You are forgetting key thing here: known issues with piston rings on Audi from that generation. No oil will solve engineering problem.

Using VRP in an engine with known problems with timing chain, while your LL04 available on any local gas station in Germany has specific test for that type of timing chain.

It's low tension piston rings that get coked up and stuck in the ring lands. I did the Berrymans B12 piston soak, BG EPR flush right after, and switched to 5w30 VR&P. Went from 400 miles to a quart of oil to not using any oil in 5000 mile runs, and you telling me it doesn't work? Sorry you cant wrap your head around that. I'll continue to use the VR&P moving forward. If the consumption comes back then I'd tell ya the oil didn't work, but until then Its obvious to me the "engineering problem" can easily be fixed with what I did here.

OK, keep doing it then.
