Nobody is suggesting that you use cheap oil in your engine.

The point I was trying to make is this:
People worry about oil too much. It's a 2-stroke engine. One of the simplest internal combustion designs ever invented. If you just put oil in the fuel--it will likey run until you are dead, or you crash it.

ANY oil we have today has got to be 10 times better than 2-stroke oil that was available 35yrs ago. Those engines are still running today. So, pick a name brand and use it. Stop worrying about it.

And yes, you will crash it, if you push your skills and ability. Thats how you get good BTW. You don't become an overnight 3D pro flying Nascar left hand turns around the field at 300' altitude.

I suggest you do some searches in this forum. Your questions and concerns have already been addressed 100 times in this forum. The information is here. You just have to find it and take the time to read it.
