The debate will rage on and on, with "tests""and "proofs" from both sides. I just don't take any chances with my beaZt: Only synth' oil goes in her. Since I've had such a great experience with Mobil 1, I'm sticking with it, not only 'cause of its "proven" qualities (here we go again!), but because it goes on promo' more often that any other brand, and I can get it for $4.95/bottle. Until I experience sump'n different, it's 5W30 Mobil 1 for my monZter!
