Curious what brand/type of two stroke oil everyone is using in their motors. Given my recent debaucle of the mystery blown powerhead, I don't want to have the same thing happen with my new/old motor. I have been doing some reading and opinions seem varied between using a good TCW-3 oil or some of the synthetic blends (XD-30, XD-50) or even full synthetics like XD-100. The synthetic blends and synthetics contain detergents which are supposed to clean out deposits, which I can see as beneficial especially in an older motor. At the same time, I've heard cautions of using them for that same reason on motors with a lot of hours on them- the detergents might knock enough crud loose that it will plug other parts of the system up. My "new" motor is a 1988 Johnson 30 hp. which appears to have been well cared for. What do you think, traditional two stroke oil or a syn-blend, or full syn?
