Why not get one of those synthetic oils, "one size fits all?" I used to have small gas cans labeled, 16:1, 25:1, 50:1, etc. Now I just mix up a gallon at a time and use it in everything. Less smoke, seems to run better, also lets me go through gas faster-a very good thing with ethanol in gas-and much easier.

Good luck,

Good idea. The synthetic 2-cycle oils are great. Use Union 76 gas. No ethanol. I use it in all my lawn equipment and motorcycle. Shell, Chevron and most other fuels have "up to 10%" ethanol.
