If you are new to the operation of 2-stroke engines, you may be unsure of the proper procedures for mixing the fuel and oil. Here are some comments that may be helpful.
First of all get a very good, high-quality gas can. I recommend using the Red Blitz 6 gallon cans. You can buy these at Wal-Mart. The price ranges anywhere from $6.99 to $15.00.Mixing Gas and Oil
The way I do it is to put one gallon of gas in the can. Then add one pint of Penzoil or the brand of oil you prefer. ( THIS IS A 50:1 MIX. ) Mix and shake well. Then finish filling the can with gas to 6 gallons.Type of Gas to use
I use Amoco 93 Octane only. This is just one man's opinion, but I have had no problems with this at all. I tore the engine down at 225 hrs and had hardly any carbon buildup at all.
You can get away with using a lower octane if you fly on a regular basis, but I do not recommend it. If you let the fuel set up for as much as three weeks, do not use it in the airplane because the octane level will have gone way down.
