I know a lot of people will disagree but I have had great luck with regular old 2-stroke oil for air cooled engines from the hardware store. The same stuff that I use in my chain saw. I have tried the more expensive synthetics. I know they likely provide better wear protection, they don't cause as much carbon, you can run less of it, etc. but for a guy like me just ''sport flying'' there just wasn't enough apparent benefit to justify the added cost. My engines run excellent on weed-wacker oil.
I generally run 32:1. That comes out to 4 ounces of oil per gallon of gasoline. You can buy the oil in small containers that mix with 1 gallon, 2 gallons or 5 gallons of gasoline to give you a specific mixture. The stuff I usually use come in a bottle with a built-in measuring cup. You squeeze the bottle until the cup fills to the level you want.
Definitely do not use the Coolpower glow fuel in your DLE. In addition to the fact that it won't work right without modifying things and could cause damage, the added cost defeats the purpose of going to economical gasoline in the first place.
I used a lot of chain saw oil and find it works as well as any. Last week at the field this all came up in the BS sessions between flights. I haven't used enough Amsoil to ever form an opinion. The guys at the field are sure against it?? I used to run there gear oil a lot in my sand dragster but wasn't ever able to afford the oil, 7 quarts and I dumped it after every weekend. Good stuff though. The Amsoil two stroke oil was too hard to come by where I was from. One thing I did discover was if I used a 100% synthetic in a new RC engine it takes forever for the ring to seat or wear in so I broke all my engines in with chain saw oil first. Klotz oil is blended and even has Castor in it, not a big deal but I'm able to find the stuff without runing all over town looking for Red Line. If the OP just follows the instructions he should be ahead of the game.
I tried Amsoil Sabre. It worked just fine for me. I even ran it at 80:1 with no problems. The cost just wasn't justified for me though. I don't get the people who say you
must use it though. If someone wants to use it, fine but it isn't absolutely necessary to have a good running, long lasting engine. Now if I was in some sort of competition situation where I pushed an engine really hard and I wanted every tiny advantage I could get then I might reconsider.
