Went to dealer today for the 10 hour checkup. He noticed my AMSOIL sticker on my sled and was mad. I told him im still running XPS-Synthetic blend (400 miles now for break in) but when reservoir goes empty im switching to amsoil interceptor oil. He said amsoil is full of AMMONIA and all it does is clean and not lubricate. I looked up amsoil interceptor and found out its API TC, JASO FC. Does this mean it isnt TC-W3? Dealer also said manual says dont use TC-W3 but all i found on page 124 in manual says (dont use NMMA TC-W, TC-W2 or TC-W3 2 stroke oils or ashless 2 stroke oils. Does this mean dont use interceptor? The only AMSOIL oils that are TC-W3 are the sabre professional and hp injector synthetic.What do i do? I have 4 gallons of interceptor synthetic oil?
