Royal Purple or Mobil 1???

RE: Royal Purple or Mobil 1???
Mobil 1 in boosted engines, like the Intimidator SS with the 3.8L S/C, and LadyT's Solstice GXP 2.0L turbo, but Mobil 1 extended performance in the Silverado Z71 5.3L, and the '82 Olds 5.0L. I'm leaning towards the Royal Purple, but in a very recent e-mail from their tech service manager, he explained to me that because of 1600 ppm of anti-wear additives in their product, it doesn't meet GM's spec of 800 ppm. It's a polution concern.
I'm soon to change to Royal Purple XPR 5-30 in the Intimidator SS (when the warranty runs out in 10k miles), but not changing yet in the other 3 vehicles.

How does that extended performance Mobil 1 work for you? Do you think I should use it in my 5.3L?

BUT, you can't go 15,000mi without changing the oil filter and rotating tires half way thru. I do that at 6,000mi, and change oil at 12,000mi.

I would use it in ANT vehicle that's not boosted, ie, turbo or s/c.
