During the winter months when I take the mower deck off and bolt on the snow blade, I make a habit of burning my left over 2-cycle boat gas (50:1) in my old Wheel Horse (15 HP B&S). It smokes a little bit when it starts up, but it runs strong with the oily fuel. It's a good way to use up last summer's unused boat gas and it saves a few buck on my snow removal costs. Am I hurting or helping my old engine with this practice?

I've ran 2 stroke fuel in my Sears bucket tractor with a 12 horse Tecumseh in it before, I've also had ATF in it as well. Basically anything in the shop to top off the tank lol. I only ever noticed that it didn't like to start when cold with the 2 stroke stuff due to the oil fouling the fire too much, but once running she'd be working like usual.

I've always seen it as extra cylinder lubricant, and valve lubricant lol. I've always mixed it up, like I'd only add stuff to the tank when it was already 3/4 tank of fresh fuel.
