XD50 or TCW3 Oil

Its a 2 stroke and I PRE MIX THE OIL and GAS! 1) Which is better to use for the motor? 2) Can you mix them together...meaning I have 12 gallons of gas and I finished out the TC W3 but it's only 9 ounces left, so can I make up the difference with 23 ounces of XD 50? 3) 87 octane or 89? THANKS! Edited by Tom W Clark on 05/20/12 - 10:29 AM

As for better, I use xd100 in my etecs only so I can get the computer to give me the better efficiency. I'm not sure I would spend the xtra $ for a 90s motor. The TCW-3 should be fine, the mix should be no different. 1985 Newport 17 w/ 70 yamaha

For the amount of boating that I get to do, its has worked fine. There has not been any ill affects that I am aware of. 2) I would not mix the oil unless you already have the XD50 ( to expensive to not use ) 3) I have always ran 87 octane through my 2 strokes ( mercury, yamaha, johnson did not matter ) Todd

This is what the manufacturer designed the motor for and precisely what they recommend using. It will be just fine.

I agree it would make no economic sense to buy XD-50 to use in his engine, TCW3 is an excellent product for his well broken in engine. Butch
