Lawn and Garden Equipment
Over the years, many different ratios of gasoline to oil have been used. But for most modern outdoor power equipment, the two most common ratios are 50:1 (with 2.6 oz. of two-stoke oil being added to 1 gal. of gasoline) and 32:1 (with 4 oz. of two-stroke oil being added to 1 gal. of gasoline).
To create your own oil and fuel blend for your outdoor power equipment, start by identifying what ratio of fuel to oil you'll need by checking your equipment's owner's manual. If it requires a 50:1 ratio, the easiest way to accomplish this is to purchase individually sized 2.6 oz. bottles of two-stoke oil and a 1 gal. gas can. Fill the gas can with 1 gal. of gasoline; then add one 2.6 oz. bottle of two-stoke oil to the gas can. If your equipment requires a 32:1 ratio, purchase individual 4 oz. bottles of two-stoke oil instead.
If you'll be going through a lot of fuel and oil in any one job, larger bottles of two-stroke oil are available for blending larger quantities of fuel. Just make sure that you properly measure the amount of oil that you're adding to the gasoline. But if you'll only be using a small amount at any given time, stick with blending just 1 gal. of gasoline to oil. Gasoline can go bad over time, and the last thing you want is old fuel sitting around that will make starting your outdoor power equipment difficult.
