I've already changed two cars over to HPL. Premium Plus 0w20 in a Camry that specs for 0w16, and will run it at least 10,000 miles. No VII 5W20 in an Accord with 120,000 miles on it, will run it at least until the Maintenance Minder says to change it...but, will probably go 10,000 miles (I have HPL 0w20 in it now...and oil consumption slowed down from 1 quart per 5000 miles to almost zero loss per 5000 miles...perhaps it cleaned the oil control rings?).
I've just bought a used Mini Countryman with 300+ HP BMW B48 with 15,000 miles, spec'd for 0W20, for which I've ordered HPL Supercar 0w30. It had two oil changes at BMW shops, at 5000 and 10000 miles, and a third change at a non-BMW shop at 15,000. I didn't trust this last oil change, drained and put in Pennzoil Euro LX 0w30, the same oil I was doing 5000 mile intervals with my previous Countryman 228 HP B48. Thankfully, the oil filter was the correct BMW filter and was clean as a whistle, I put it right back in. I'll probably go at least 7500 with the HPL, but, I might do an oil analysis and check the TBN, and if everything looks good, continue to 10,000 miles.
One of the benefits of these HPL oils is the ability to run longer OCI's, and the Camry and Accord will have no problems running 10,000 miles. The B48 makes me a bit wary because of the turbo, and they have dialed up 300+ HP on a 2.0 L engine, but, I don't run it very hard. Every once in a while I'll floor it for a few seconds, or go on some twisty roads and hold the RPM's up a bit, but, compared to tracking it...it's operating in relatively tame conditions for the most part. With at least one long highway run per week, I'm thinking it gets hot enough to help keep it healthy.
