gettin close to 3k on the 08 and am going to do the switch to syntetic (think i'm about 2400 miles on the clock right now). There are 3 brands of synthetics i'm tryin to decide which to run: suzuki synthetic, amsoil, or mobil 1. I ran amsoil in my last gixxer 750 and was always happy with it, i think i have about 3 quarts still sitting in the garage of amsoil. I know a lot run mobil 1 and are happy with it, but then again can't go wrong with oem suzuki synthetic. I probably like amsoil the best, but it is a bit more expensive and sometimes hard to get. Any suggestions
