Mine has to be the most recent. Yard Machines 675exi Briggs and Stratton. 163 cc. MTD. Never Change oil model. I do, of course. Lasting a long while. Use Sta-bil, some MMO, some left over Gumout, and lately Sta-bil Small Engine Pro in the oil and gas.
It seems like the fail point on two other mowers of mine have been the carbs. But this Yard Machine has been doing great with using the above additives.
