hello tim,
it`s not unusual yo come accross people who expect you to know better than ask certain questions,
Anyway , as for fuel it should give some recomendations in teh instruction booklet as to the Percentage (type ) of fuel recomended, i think it may be 16% nitro content, but i`ll find out for you .
As for the oil, it`s called after run oil . It`s designed to protect the cylinder liner and piston from contaminants in the fuel if the engine is going to be left for a period of time , these stick to teh walls of teh cylinder and can cause pitting and corrosion. Only really necessary if there are long periods of non use of the model. but not a bad habit to get into
Now your thinking of engine lub`ing ?
the fuel has cleansers and necessary lub`s in it`s content, additional additives are not necessary for this purpose,there are various types of fuels available with different types and contents of oil in them.
A good idea when finnished runing the model is too empty the fuel tank, as the fuel congeels in teh lines, carb etc. Remove the glo plug and pull the pull start a few times to dry out the engine, after run oil is then applied into the cylinder via the glow plug hole.
