Many high performance vehicles have no warranty if you don't run Mobil 1 full synthetic...a Viper for example. All VW diesel have no warranty if not run on full synthetic.
More & more new cars use it & I see no reason why a PW wouldn't benefit but if you're using it thinking you can run more than 5000 miles between changes or longer intervals...stick with regular oil...you've missed the point.
