If you are like a lot of people living in the suburbs or on a farm or lifestyle block, you probably have several 2 cycle engines such as a weed eater, chainsaw, blower, etc. Most of these engines take different mixtures 1/50, 1/32 etc. All the instructions tell how to mix one gallon, however, you usually only need a tank or two at a time, and a gallon will go bad before it is used up. Nobody needs several gallons of bad gas mixed at different ratios; the solution is to mix a tank at a time.
Always stabilize your gas before you start. It will keep the gas fresh for longer periods of time and protect your engines from gumming up. One example is STA-BIL, however, there are many others available.

Use a measuring device for small amounts, 2oz- 1oz- 1/2 oz and 1/4 oz. There are many available. You will also need small mixing containers, 1⁄2 gallon (1.9 L) and quart measuring cups will take care of most of your needs.

If your engine calls for a 1/32 mixture that is 1 oz of oil to 32 oz of gas, or 1/2oz of oil to 16oz of gas, or 1/4 oz oil to 8 oz. gas, mix only what you need at the time.
Find a piece of cardboard or plywood and list all your equipment on it.Include the ratios that they require, and the recipe for a tank of gas. Put this on the garage wall; this will keep you from looking up the manual each time you use it.
