i use it cause i get a discount but i think i should of never used synthetic because i heard i will seek out any possible cracks and leak out the sides of your engine if it can. and i have about 85k on my engine now so i will switch back to just regular castrol now even though its not good to switch like that.
I'm running it. I haven't had any problems. Right after I put it in it felt smoother to me, but that is about as subjective as the butt dyno.
I would say any synthetic is worth the money over regular oil because you can go twice as long without changing it, plus it's better oil. My buddy bimmer comes factory with mobile1 and the recommended mileage between oil changes is 15k. Something tells me this is going to open a can of worms...
