Journal Jac_no_k's Journal: hacking fuel
stupid friday morning... I'm having trouble concentrating on work...
so I decided to figure out when it would be cost effective to blend 87 octane fuel with 114 octane toluene compared to 91 octane fuel.
so to come to a 91 octance blend, it takes 85% (87 octane fuel) and 15% (114 octane toluene).
- assuming that 91 octane will be roughly 10% more in cost compared to 87 octane. (so when a gallon of 87 octane is $2, 91 octane is $2.20)
- assuming the price of Toluene doesn't fluctuate with the market, I fixed it $5 a gallon.
It turns out the break even point is $3 for 87 octane. For a given gallon, 85% 87 octane is $2.56 plus 15% Toluene is $0.74 for a total of $3.30 a gallon for a blended 91 octane fuel.
