Does anyone know the % of castor and synthetic in Morgan fuel (omega) 10% nitro. Ex. 18% total 9% castor 9% synthetic. Just curious. Thinking about buying a MVVS .21 and the manufacturer states at least 20% oil and at least half of that being castor.

I don't know the exact percentage of oil in Omega these days, but I know it isn't twenty percent and the castor oil content is only a few percent and certainly not 50%.

Dar Zeelon and Pe Reivers are the MVVS experts here on RCU. Hey fellas!!!! <G>

As an aside, Omega is great fuel. I use it myself when I can locate it, along with Wildcat and a few other brands (Gotta try some Cooper Fuel one of these days).

I keep a few bottles of Sig castor oil around the premises. Adding three or four ounces of castor oil to your fuel will give you a safety margin for those special situations.

I have one MVVS engine, a .61, but haven't ran it as yet. But when I do, I will probably end up spiking my synth/castor blended fuel with three or four ounces of castor oil. Maybe Pe and Dar can comment on whether this will or will not be sufficient for the MVVS .61 and a .21...?

Layne,


Morgan Fuels advertise their [link=http://www.morganfuel.com/omega_blends.htm]Omega series fuels[/link] as being 17% oil, mixed in a 30/70 ratio. This means 5.1% castor oil and 11.9% synthetic oil.

If you add enough BeNOL, or Sig/Bakers AA to make half the oil castor, or 6.8%, your fuel would be nearly 22.3% oil.

I would say to use another fuel base, so as not to achieve this very oily mix.


Sig Champion series fuels are 20% 50/50 oil, as they come from the factory and they cost no more than Morgan.

PowerMaster GMA (5% and 10%) fuels are 22% 50/50 oil.

I am sure there are others that are pre-mixed to your exact preferrence.


I personally start with Model Technics Duraglow 5% and add to it 6.2% BeNOL castor, getting 20% total oil, of which 56% is castor.

Layne, you can order fuel directly from Fox in your choice of nitro % and 20% all castor, 20% 50/50 syn/castor or 75/25 syn/castor blend. I have used the 20% castor and the 20% 50/50 blend, excellent fuel.

When running the engine with low oil in fuel, must be little rich mixture to make enough oil in crankcase where moving parts need oil.
The bearings can not last long as other Saito who are using 23% oil in fuel and can not run leaned then it will make noise of the engine.
