I am contemplating the purchase of a 2009 GZ 250 w/ @ 1000 miles; the dealer will do a complimentary first service (oil will be Spectro conventional 10w-40); I plan on doing my own oil changes, chain lube, etc & wondering what oil y'all use in your GZ's...thanks

I am currently sitting on a stash of Valvoline 4-stroke 10w-40 conventional motorcycle oil & was told by the dealer to wait until the 4K service before switching to a synthetic or synthetic blend...any truth to this? thanks
