Small Engines (Lawn Mowers, etc.): Craftsman 37.7 Gas Brushwacker, 2 stroke engines, synthetic motor oil


Question
John, I just was given an old brushwacker. The manual states that the fuel mix should be a 16:1 ratio with Leaded gas. my 2 stroke oil is a 50:1 if I mix it in 1 gallon of gas. Should I assume that this new piece of equipment has to have a special mixture rather than all of the other 2 stroke engines that I have?  What do I need to do?  

Answer
Hello Daniel:

All Two Stroke Engines will use a 50 to 1 Ratio using today's Two Stroke Oils.  I once used an Old Chainsaw probably from the 1960s, that had a sticker on it that said to use a 25 to 1 Fuel/Oil Ratio, but that would have been using Two Stroke Oils of the Time Period the Chainsaw was Manufactured.  In that Chainsaw I used 50 to 1 ratio with No Problems.  Today's Two Stroke Oils compared to Yesteryears are More Efficient at Lubricating.  It is like comparing today's Synthetic Motor Oil to Motor Oils of Decades ago.  All the Equipment I use in Landscaping, anything from a Weed Eater, Leaf Blower, Chainsaw, Hedge Trimmer, use 50 to 1 ratio, and I use All Types of Makes and Models, Stihl, Homelite, Husqvarna, Shindaiwa, and Echo, Sears.  I mix up a 5 Gallon Fuel can and use it in all of the Equipment for my customers and for my Grounds Maintnance and Landscaping Service. Hope this Helps. I am Here if You Require More Assistance. Let me Know What Happens, Please. Thanks.

Good Luck
