RE: What fuel do you use in your Saito engines
Hey Guys, I need to add my two cents............Saito needs to go back to making four strokes and leave the oil to us.
I'm not sure about the very latest synthetics but I was on a test team many years ago when synthetics came out.
We tested them at Daytona in an air cooled formula vee. It destroyed the engine, the tranny and differential was fine.
After extensive testing we found that synthetic oil when getting near the combustion chamber.... in other words getting hot,.. would burn away leaving no protection.
Where as castor would also burn, but would not go away.....Just turned brown.
I run syn/castor in my helicopter and have had excellent success with it ...(OS 50 hyper)
I run syn/castor blend in my cars also....I have an OS 21 that is 14 years old. still running strong. This engine doesn't have a ring.....much tighter clearances than the Saito.
I have to agree running straight castor is to much, but a little goes a long way in protecting your engine.
We could discuss this for a long time, but I personally will run syn/castor in my Saito and if any thing ever happened to it I will just tell them I ran what they recommended.
I hope this helps a little
