Hello my name is Acton and on behalf of Expert Village.com. Today we are going to talk about how to mix two-stroke fuel for your two stroke engine. So if you are wondering about whether or not you even have a two stroke simply look on your lawnmower and it will either say on your gas tank, gas lid or it will say in your owner’s manual. If you have any doubts, double check. Very important. Also if you are wondering what sort of ratio you take, again it should be listed on your gas take, on your gas lid or in your owner’s manual. So, first thing that you are going to need is some sort of type of measuring cup, some two-stroke oil specifically, empty gas for your fuel mix and then another gas tank of straight gas. So let’s say we take 40-1 mix for our lawnmowers. I usually use this brand because on the back they have a little chart that will tell me how many gallons of gas to how many ounces of oil I will need for ratio I have. Come over here. I have one gallon of gas and I want to make it a 40-1 mix and on the back it says I am going to need 3.2 ounces of oil for my one gallon of gas. So open it up. Unfortunately I have 8 ounces here so again I need to measure out. I got 2 and 4 ounces so I am going to measure between the 2 and 4. A little more than 3.2 ounces, all right. Don’t worry about getting the exact just as long as you have at least 3 ounces. It is better to run it a little bit rich than too lean. Too lean means that you are going to cause damage into your cylinder because there is not enough lubrication to your oil mix. Pour the oil into my tank, take my gas, pour a little bit in, and put the cap back on cause you need to shake it. Actually shake with the lid off so you don’t get up too much fumes and you are ready to go.
