I have a ETEC 200 H.O 2009 and i blew the motor off last year and I now have a new powerhead. When they switched the power head they filled my oil tank with xd50 but i always used xd100, i have about a quarter tank of xd50 remaining in there and i want to switch to xd100, how should i do that?
Just throw my xd100 in there? Remove the oil tank and empty the xd50 before?
