RE: what synthetic oils are out their?
I mix my own fuel, I use 100% castor, problem is it sticks to everything. I mixed a 50-50 blend (useing a 20/20 wildcat fuel) just to see if it made a dfference in castors "stickyness" and the oil was much easier to wipe offthe plane and didn't gum up my engines as bad. The only reason I'm really using symtjetics is to make the castor less sticky...i agree that castors the best out their for the price....
