Its pure Methanol which I pick up at the local Go-Kart shop for $3.95 a gallon. I then buy a few quarts of Blenzol Green 50/50 Synthetic Castor blend.

I use an 18% oil blend into 1 gallon of fuel.

There are 144 ounces of fuel if I am not mistaken. If you do the math I BELIEVE it comes out to 23 ounces of oil per gallon. I shake it up really hard and stir too to make sure that its mixed well. I store it in my garage and try to keep it out of the sun just because.

I will find the sheet I made and post tommorow when I have some time, Steven.

After I use up the six gallons I have, I'll probably be going to home brew too, although I can get Omega FAI fuel for not all that much more than what it'll cost me to mix it myself.

Status: offline 		what I have been reading says these engines love 20% castor and 80% Methanol...

I have to wonder if:

1. adding acetone would help idle
2. a squirt of amorall for goog luck would give good luck (not sure why folks do this one ;-)

so is it castor or a castor /syn blend? How about any acetone? I KNOW there are brewmasters out there who have some opionons ... pls do share. The Moki is really impressing me :-)

what do you guys think?

Status: offline 		I have a Moki 1.80 that I have flogged the guts out of for 8 years running with 20% Coolpower and 10% nitro.

I know others will say that you dont need the nitro and could even be detrimental to the engines life span.

The engine is a power house and has never missed a beat turning a Bolly 18x10 with the Bolly EQ 3000 pipe.

Cheers

Phil

Status: offline 		The old squirt of Armor All trick is to keep the fuel from foaming; works wonders.

Moki's also run great on 12% oil contrary to popular belief; and you'll get another 300 or so RPM.

I know at least 3 people that run 0% nitro and 10% full synthetic oil on the 2.10 and they have 100's flights on them with no problems.

Being that the big Supertigre and OS motors advertise low oil contents; I am not sure why the Moki needs anywhere near 20% oil.

I've heard many stories about lower oil contents and no doubt it works for some. However, I have also seen fried engines where people have tried to use low oil contents and I really wonder why. Is there flying going to notice the small percentage gain in performance?

I know their hip pocket will notice if they fry the engine.

I dont claim that my idea is the best, but I know the engine is still going like a train after many long hours of work.

Cheers

Phil

I think they gravitate toward a less mess and lower cost per gallon: these a 3-4 gallon per weekend IMAC guys.

Status: offline 		G'day Warren

Understand your point and certainly know the cost of fuel is a consideration, but I would rather be flying than replacing engines and the little extra fuel cost could be viewed as something like an insurance policy.

Cheers

Phil

Status: offline 		When in doubt, follow the recommendations of the mfg/distributor! Gerard (the Moki importer) calls for SOME castor oil and very little nitro. I have used Mach7, 5% nitro with half-and-half castor/synthetic with great results. You can also get this with all castor or 25% castor direct from Morgan Fuels. Buying three cases at a time, I pay $11.00 per gallon, including UPS AND hazmat. To me, it"s not worth the time and trouble to buy everything separately and mix my own. I also run my 2.10 through 3/32 fuel line while some other fuels require 1/8 line. This tells me I am getting better fuel economy than they are. Also note that when you buy nitro, by law it cannot be 100% pure for safety reasons. An old boat racer buddy used to buy a barrel(!) of 50% nitro/50%alcohol and add castor oil to make 35% racing fuel. It worked fine.

Status: offline 		Hi guys,
I've just bought my first Moki( )1.80,and would like to know if 5%castor and 15%syn with 5%nitro will hurt this? As this is all i buy for all my smaller planes but i might have to resort to making my own fuel if they suck as much fuel as ppl say.

I've been told that i can order the same fuel in at 10/10 mix with no nitro if i want.Id like to have some syn oil for the clean burning it has,I've run a 46 with just castor and it is a pain getting the sludge off at the end of the day.

Apologies for the late reply, but I have been away for a ocuple of weeks.

The fuel you want to use will keep your Moki more than happy.

Cheers

Status: offline 		Thanks Phil..

I'll be running it on 10/10 mix i think.I dont realy see the need for nitro in this motor, as a fellow flyer(also Phil)has a 1.8 in a high wing glider tug and it has oodles of power and a very low idle,he even has trouble stoping it.

I cant wait to fit it in its plane and try it out.

Half half is fine.

I always use a little nitro just to help with idle etc, but I'm in Canberra so elevation is 688 meters.

I know you will enjoy the Moki. I now have 4 and each one strong yet docile handling

Cheers

Phil
