Bax - I'm not sure where you get your pricing from, but methanol retails for about $2.50-$4.00/gal depending on location. Oil is $7-$10/Qt or $25-$40/Gal for average oils (castor, Klotz, cool power, etc). Nitro is on average about $50-$60/Gal in small quantities which you're accurate on. Around my neck of the woods, aircraft fuel is $30-$38/gal for 5-15% nitro and car fuel 20-30% nitro is $32-$40/gal depending on brand. Mixing my own fuel cuts my fuel cost by 60% or better.

Of course this has nothing to do with the thread subject but oh well.
