if you have castor in your fuel you will have an nonremoveable film of oil on everything in the motor too! good for flying season i never use any "after run" oil while i am flying the plane. now when its time to put it up for the winter yiou can add some type of oil if you like, just remember to spin the prop about once a week to keep it on the parts because it will be all on the bottom of the engine!


i just make sure the engine is empty of fuel at the end of the day and put her up!

goin on 10 yrs same engine noooo problems!

of course you will get about a 50/50 mix of people who say use it to those who say don't use it! just do what makes you feel safer!
