RE: Which Fuel to use?

Andy, the OS 46's will run just fine on 10% nitro.

Your 91FX will fair better also.

You get a little better fuel economy with less nitro also.

RE: Which Fuel to use?

Been using the Wildcat 10% 2&4 stroke in everything with stunning results. I carry nothing else to the field. I see no reason to make this decision difficult. Use the best.....Discard the rest.

I have a few engines I’ve purchased and I would like to get opinions on which fuel to use for each engine. Obviously I would like to keep my fuel purchases to only 1 or 2 different fuels; I don’t want to lug around 4 different gallons of fuel for different engines. If none of these fuels will work for a particular engine, please recommend one.<o:p></o:p>Engines I have

Fuels I have

Wildcat 2&4 Cycle 10% Nitro
Cool Power Super T
Cool Power 15% Total Synthetic
Omega 15% Castor/ Synthetic

<o:p></o:p>Thanks.

In the 4 strokes I would opt for a fuel with a high percentage or 100% synthetic.. Nitro content >10% would be advised for easier tuning and reliable running.

In th 2 strokes, a fuel with a small percentage of castor or again, 100% high quality synthetic would be beneficial.

Of the fuels you currentlyhave in your stock, I'd opt for the Omega 15% Castor /synthetic.

If you can cope with 2 fuesl, then keep the Coolpower for the 4 strokes and the Omega for the 2strokes. Eitehr one of these will work just fine in your engine. Select the Nitro content for smooth 4 stroke running and be done with it.

What I would keep in stock is a range of plugs..

RE: Which Fuel to use?

Regular Cool Power is a slow death for your four stroke unless you use after run oil very generously

RE: Which Fuel to use?

To the OP,
Since you live in Ohio I recommend that you look for S&W fuel, which is manufactured nearby in Penna. It may be less expensive than Coolpower and the others because of reduced shipping costs. www.s-whobby.com Their "standard blend aircraft fuel" is 18% synthetic, 2% castor and comes in whatever nitro content you want. I use 10% in my 2-strokes and 4-strokes. The 2% castor has caused no problems in my engines, some of which are over 10 years old. And who knows, possibly the castor content has prevented bearings from rusting and prevented damage from a lean run.
