I put Rotella T syn in my bike, Suzuki VL1500 last fall, Sept. or Oct. can't remember. Have about 1500 miles on the oil, didn't ride much this winter. Ya think it's ok to leave it for another 1500 or change it out? I'm thinking of some Mobil truck & suv 5w40 for the next change. But I don't want to waste the oil.
