stevebo-(Moderator) 8,534 #2 Posted November 21, 2010 It is just lightweight oil. I do it every once in a while. You can also add it to the gas. I also use it to winterize my boat by pouring it into the carbs until it floods out and cuts the motor. It is just coating the cylinder walls. Share this post Link to post Share on other sites
MaineDad 87 #3 Posted November 21, 2010 I use 1 ounce of MMO per gallon of gas every time I gas up. Been doing it for years and am a believer... Share this post Link to post Share on other sites
KC9KAS 4,744 #4 Posted November 21, 2010 I know an auto mechanic that used to add a quart of oil to a tank of gasoline after overhauling the engine. His idea was to get plenty of oil on the cylinder walls during engine break-in. Share this post Link to post Share on other sites
