I know you guys are going to hate me but basicly I'm taking the speedmaster off the road and I don't want to spend $70.00 for 4-quarts of oil,,, the bike is at 4900 miles and I haven't been riding it much but it should get a oil change (and 5000 mile inspection) at 5000.

I see what you mean about the engine and tranny connected but as far as the synthetic thats in there now can it just sit in there and still be okay in a couple years if I don't start the bike?



No. Conventional oils are acidic. Thats the least desirable thing you would do. If you are looking at long term storage, use full synthetic (a good brand like Mobile, Amsiol, Redline, Lucas) and a storage fogging oil. don't forget the fuel stabilizer or you'll be rebuilding carbs, too.

To answer your original post question: If you were running a quality full synth oil, most are completely compatible with a conventional oil.

Don't cheap out. It'll cost you more in the long run.

I should tell you I'm an Amsoil dealer. I'm not selling anything here- just giving advice. You are welcome to PM me for more info. Fast Eddy sells the stuff on his site, I'm not trying to muscle in- just help you out.
