Which oil are you lookin' at. There is Mobil 1 0w40, Mobil 1 5w40 and some new stuff that I haven't seen yet Mobil 1 10w40 High Mileage. The 0w40 is pretty good oil with some moly just like the bike specific stuff. The 5w40 has no moly and is way down on zinc. I haven't seen an oil analysis on the 10w40 High Mileage yet. I've used the Mobil 1 15w50 (car stuff) car stuff in lots of bikes but the high viscosity caused clunky shifting when cold so I changed to the Mobil 1 MX4T 10w40 which I got from the local Autozone for $26.60 a case because the guy was overstocked.
