My question in all of this is what fuel is good for use in just regular outboard engines? I've run Omega and Cool Power 15% to get things in the water and tested and it's ok. Locally the only fuels available are Morgan's products which I've used for decades in planes and helis and have no complaints. Car fuels such as Traaxas are also available. I'm not prepared just yet to run 50-60% fuels and there is no convenient way to get it, it'll have to be ordered. Can I use something like Traaxas 20% fuel? My concern is oil content. I don't want to damage an engine (I'm running K&B .21 and .40 outboards) just running around the pond. When I get to my first race I'll probably stay with 20% until I get used to running in traffic and rough water. Opinions? Thanks.
