Re: Mix Ratio
As Chris says, this is an oil injected motor.. I have one and all I did was take the hose coming off the oil pump that went into the fuel line off and drilled a hole in the top of the oil tank. In essence the oil is going from the tank into the pump and back into the tank...this way I didn't need to remove the oil pump etc...I mix in all of my motors(9) as I will never have failure due to lack of oil...In our big motors we mix 40 to 1 but not necessary on the 90....
