I've read all the posts for making your own fuel and I would like to know exactly what kind of synthetic oil I can buy at a local auto parts store or maybe a motorcycle shop. The methanol and castor is no problem, but all the synth that I have tried will not mix in methanol. It just goes to the bottom like water in oil. If I have to order the oil or drive a considerable distance then I might as well go to the hobby shop and buy the fuel. I live in Lufkin,Tx which is about 120 miles from houston, which has the nearest H/S. What I'm trying to avoid is using a tank of gas in my car every time I need airplane fuel. one more thing, for a 0% nitro 20% oil mix how many ounces of oil for 1 gallon of methanol. All I've been reading is percentages.

One gallon is 128 oz.

102.4 fl oz of methanol + 25.6 fl oz of oil = 128 fl oz of 0% nitro, 20% oil glow fuel (1 gal).

or easier since most oil comes in qt size (32 oz):

160 fl oz of methanol + 1 qt of oil = 192 fl oz of 0% nitro, 20% oil glow fuel (1.5 gal)

and for a larger quantity and even easier:

4 gal of methanol + 1 gal of oil = 5 gal of 0% nitro, 20% oil glow fuel.

Unless your auto/motorcycle shop stocks synthetic (usually Klotz) that mixes with methanol, none of the car products (ie Mobil 1, Castrol Syntec, etc.) will mix with methanol.

I get my oil (CoolPower oil, light with castor or for all syn, get it without castor) from this site: http://www.tommyskarts.com/Cat.Oils.htm
It is the same stuff that CoolPower sells and at $52/4gal, I believe it is a very good deal

Addict2RC, what does Tommy's charge you for shipping a case of Coolpower oil?
I take it your experiences dealing with this supplier have been positive?

Martyg,

Normally, they charge about $20 for a case/4 gal. But for the month of January, it is free shipping. A hell of a deal ($52/4 gal) of Coolpower oil.

Even with the shipping charge, it still beats a lot of places.

Any idea the difference between light med and heavy, except for the obvious? I wonder which does coolpower use for Rc fuel-light, med or hvy?

FlyNBHappy

My Feedback: (7)

Since these oils are labeled for 4-cycle use in karts, light is for stock, med is for modified stock, and heavy for super stock. I've been using the light version with castor and everything seems fine. I'm thinking of ordering some without castor and see if there is a difference.

Addict2RC, any idea how much castor in in their light Castor/Synthetic blend oil?

My Feedback: (7)

Martyg,

I don't know the exact, but I'm guessing it is 70 syn / 30 castor. This is the percentages of their Omega glow fuel.

Just bought 3 gals of the light with castor in quarts because the 1 gals were out. $52, free shipping. I run zero nitro so should make pretty inexpensive fuel.

I am trying to get into homebrewing and have a few questions.

Is 20% oil a 4:1 mix? 4 part meth. 1 part oil.
What kind of castor should be used? The stuff at the pharmacy?
Would a 50/50 castor/syn mix be good?

Thank you for your help.

My Feedback: (7)

Yes, 20% oil by volume is 4 part meth, 1 part oil. This is for FAI fuel (0% nitro).

Don't buy the over the counter castor oil for human consumption. Buy the castor oil you get at a motorcycle/go-kart/racing shop made to mix with methanol (Klotz Benol, Baker's Castor, etc.). Check the Sig website. They sell the Baker's castor oil for about $25/gal. Or check the the go-kart website listed above.

50/50 castor/syn is a good all-around mix. This is a highly debated topic, so just find something that works for you. To keep it simple, I either use 100% castor, or 100% synthetic; whatever is cheaper at purchasing time. I haven't notice much difference in engine performance yet.

BaronSchwab

What's the differance in the Castor? I thought you just wanted them to be able to mix.

FlyNBHappy

My Feedback: (7)

I'm assuming you're asking about over the counter castor oil vs. racing castor oil and not between different brands. From previous posts, the racing castor oil goes through a degumned process. Unsure about pharmacy castor oil.

BaronSchwab

You got the ? right. Thanks for your help.

So where can a guy find methanol?

flipa10

Try car racing shop. The one I frequent has methanol for $3 a gallon and if you really need, nitromethane for $10 a quart. I don't use it in any of my engines. Haven't missed it.

BaronSchwab

OK.

Dr Nitro

Try Cooper Fuels, they sell glow fuel synthetic oil that is IMO better than the rest available for sale out there. No info on the oil on their web site but contact info is there or drob them an e-mail at [email protected]

ADDICT2RC,

Are you sure the 4 cycle Kart Coolpower is ok for use in 2 stroke applications. I purchased a case of the Med weight kart oil and found it to be quite thinner that the Coolpower model oil. I'm just concerned. I'm sure that it will work but will it cause premature wear to engine parts....

Mungam,

I'm sure it works fine for my engines for the past several years (about five 15-30 minutes flights / week per engine). And that is with the light oil running with no nitro. If you're concerned, please by all means go with another oil product.

MUNGAM

ADDICT2RC,

I did a little more investigating and called Morgans. The technician there said the 4 cycle oil is fine to use in two stroke applications. It's the same base oil with different additives. He did say that it may turn the fuel a funky color over time but functionally it will be fine. I'm glad , I have two case sitting in my garage. Thanks for the tip.

Mungam,

Thanks for checking. The "funky color" they're talking about is dark brown/gray. The original fuel after mixing is clear to light yellow. Over time, the fuel changes to the darker color. I'm not sure, but either exposure to air and/or sunlight affects the color of the fuel. Either way, it does not affect the fuel performance at all. The first tank runs just the same as the last tank of the fuel.
