Tell me about oil
Looking for recommendations on 2-cycle oil for fuel mix on Quadra and Zenoah engines. One new and one older motors. 20:1 mixtures but what brand of oil? All synthetic or a blend?

can opened....worms everywhere... lol
Seriously, that debate will rage on and on and on, be prepared for a slew of arguments, suggestions, complaints, I-know-a-guy whose engine gained 500rpm just by putting an ounce of chipfat in his oil...blah blah blah.
There are many brands and some of them work better in different conditions. I use whats available in easy access, decent price....and run it at suggested spec. For me thats Stihl HP for my Saito Gassers and the same or Redline in the 2-strokes.....works for me, is available.

I agree with the whatever is available at a reasonable price. My minimum is that it must be "approved for use in air cooled engines". No outboard oil for instance.
And unless you are running one of the sub 15cc baby gassers (which actually need 20:1). 32:1 mixture is plenty of oil in the bigger stuff.
The 20:1 mixture suggestions you see for these bigger engines is an old spec. It does work, but it leaves way more mess on the planes than necessary.

They do push Red Line but they also used to be OK with Amsoil. It makes good sense that they try to get everyone running Red Line. When engines come in for service it's good to have that base line. I used to have a DA 150 S/N 257. During its lifetime it was run on no less then 6 different brands of oil. It saw life on 4 different airplanes. I estimate that when it hit the ground it had over 2,000 flights on it. Like I said earlier, pick a brand that is easy to get, use the correct ratio and it's a non issue.

A retired friend of mine built go kart racing engines for a living, he is also an RC'er. When i first started flying with gasoline engines he told me that if i used Red Line i would never have an oil related failure. That convinced me, he is an expert, so i followed his advice, i have been using Red Line at 40 : 1 for years with no issues.

I have used Triboron from Sweden for a couple of years on my gas engines.
I have burned 60-70 liters on my different 1-2 cylnders.
Its alleged it is conteining the element Boron.
It is mixed 1:100.
I have not have any problems so far.
