That's too much oil by nearly double. See if you can find pure methanol somewhere. Then buy 20% nitro 18% oil glow fuel and mix it with one gallon of methanol. (Methyl Alcohol) Then mix that with two parts of high test gasoline for the proper Gas/Glow mixture.

You can't just use gasoline to water down high oil content glow fuel, as this will also decrease the methanol in the mixture which is vital to the glow plug operation.
