I am running 30% Cool Power heli fuel in my saito 4 strokes. This has really helped with idle and overall performance. I would however like to add about 2% castor for insurance against leaning out in the air or corrision. My LHS has gallons of pure castor for sale but I was wondering about the use of medical grade castor(I am a Pharmacist with easy availability). I have seen this mentioned in diesel fuel mixing but am not sure if it would be ok for glow.
Thanks,
