I'm a huge fan of RP. I've had nothing but fantastic luck with the oil. I was dissapointed when I noticed that GM voids warranties when non DEXOS 1 (certified) oils are used...
Royal Purple hadn't been through certification...
I emailed RP about 2-3 months ago and they stated they had no plans to certify the oil - much to my dismay...
I'm done with the factory oil at 9,000 miles, I'm changing it not because I ran out of GM % life, but because there is no oil on the freaking dipstick (as to be expected on a 9,000 mile oil change)
My 06 2.0TFsi Passat went through a quart every 2,500 miles and VW said that was normal... And it was. Turbo cars lose oil period. The oil rings on the 1.4t are intentionally not overly taught this improves life of the rings and improves fuel economy at the expense of a bit of oil here and there...
Anyways. I saw at Autozone new RP Dexos1 approved oil. It's CRAZY loot but I love the oil so much. I'll give my impressions. Unbiased impressions. For instance, RP on my wifes old 2002 Saturn, I notcied no difference. On my Supra and my 08 Aura XR I noticed a significant difference (especially on the Soup).
We shall see how this goes.
