Interesting you put it in a Euro vehicle. I too have installed Valvoline Restore & Protect 5-30 in our new to us 85,000 mile, 2018 Audi Q7 3.0T that was gobbling oil at a rate of about 1 QT in 500 miles or so. They are notorious for low tension ring sticking. I took the time to do a Berryman's B-12 piston soak & a BG EPR engine flush. I then installed the Valvoline Restore & Protect. We've put only 200 miles on it so far and have been concerned about not putting in Euro oil with the required >3.5 HTHS, but what choice do you have while trying to clean up the piston ring lands and the stuck rings. After my pistons cleaning, flush and install of this oil, we drove 40 miles on way up to the Twin Cities and watched the oil level go down and use about 1/4 quart of oil, on the way back and since it hasn't used any oil since, so thats a good sign I think. Most people that have done the Berryman's B-12 piston soak have fixed the oil consumption on their 3.0t engines, but without clean pistons and oil rings it will comeback right, so exactly the reason to use the Restore & Protect, after all the Euro oils dont seem to be working to prevent stuck oil rings in this engine.
I figure to run this first change of R&P to 2000 miles, change and run another 5000 mile change of the R&P, take a sample and send it off to Blackstone to see the engine wear figures and how this oil does.
How important is the >3.5 HTHS Euro requirements here in the US where we don't have the autobahn anyway, not running the bigs speeds pushing up the oil temps? Here in the US we run lower speeds, use less power and run lower sustained RPM while causing. Someone correct me if I'm thinking wrong here. Typically I'd be running my preferred M1 0-40 in this engine, but because of the ring sticking these engines are know for I figured I would be better off trying to clean the piston ring lands with this R&P product first before switching back to the M1 0-40 first. If this R&P works as advertised it may take a few changes ever now and again to keep these rings from sticking again. Or use the BG EPR flush every few changes perhaps... I don't like taking these risks with flushes or "non approved" engine oils, but I figure doing nothing will score the cylinders, pistons and eventually take the engine out anyway. Borescope shows the cylinder walls are in good shape with no scoring now.
