this is old to most of you but a dealer told me that 100% syth.oils for premix or oil injection systems is to thin for use in 2 cyl. eng. looking for web site on this subject besides nmma
TCW-3 rated synthetic oil will work just fine in your 2 stroke outboard, 1Bill2Boat.<br /><br />The only harm it would do is to your wallet.<br /><br />Good luck.
I agree with JB, as long as it is TC-W3 oil it will be fine. Amsoil full synthetic injector/pre-mix has been around for 17 years. It wouldn't be around that long if was causing problems. You can get more info at www.UltimateOilTechnology.com/marine.htm
