unfourtantly their is a reason.
oil and nitro are expensive. ill use wildcat as a example because i know what oils they are useing

that oil cost $45 a gallon, but im sure wildcat gets it much cheaper, we'll say $25 for augument sake
nitro (hold onto your wallets) http://www.worldwideracingfuels.com/...oductid=790067 is 80 bucks a gallon, we'll say klotz gets it for $50
methanol runs at 2 bucks a gallon
and dont forget the plastic container 25 cents, if that
.so for a gallon of fuel with 20% oil (5 dollars worth of oil) 10% nitro ($5 worth of nitro) and $2 bucks worth of methanol. thats 12 a gallon. we get it for 15-20 a gallon
so no its not going to get any cheaper but their may be a solution (one of you engine guru's could tell me if this is even possible) put needle berings instead of bushings on the con rod (like they do in gasoline engines). that would allow us to run 3% oil instead of 18%. then raise the compression and run no nitro. then we could see prices of 5 bucks a gallon with much longer run times because their is more burnable material (methanol) in the fuel. the problem is the engines would be more sensitive running no nitro.
the key is the needle bearings, those would really help. im guessing its much harder than i think it would be, or they would have done it by now (their would be less friction so the engine would have more power)
