Hi, I just tried the Coleman fuel and Marvel Mystery oil mix and works great. Thanks for another good piece of advice. Doesn’t stink the house up as bad 😂

Haaa you’re welcome dude, yeah… once you go to Coleman fuel and MMO, you’ll never go back.  Clean burning, virtually no carbon deposits or smoke..  I love it. The MMO is also great on the O-rings… it prevents swelling unlike some 2 stroke oils.
