RE: best oil to use
I was skeptical too at first! Just didn't sound like enough or was correct. I am just saying that I have owned several DA, Zenoah and now a Saito FG-36 that I am successfully running the oil. No failures or early overhauls. After all, the DA engines are high enough quality, that we do overhaul them. I truly don't care what anyone else runs or likes for thier engines. Unless you have stock in the oil company, what's it matter?
