I have an 8 gallon tank, so here is the math...(I need to get to 100+/- octane)
Race Fuel-$7.85/Gallon (when buying barrel) per tank fill up-$62.80
AvGas- $3.89 Per tank fill up- $31.10
91 ($1.93)+ Torco (32oz. bottle= $18 or $.56/ounce)- 8 gallons of premium ($15.44 + 24 ounces of Torco ($13.49)= $28.93 per tank
the prices are obviously flexible regionally, but are clearly directionally accurate...Additionally, some may be comfy with avgas, some not, some might think torco is snake oil...have done enough research personally to have zero worries about it...and it is easier to mix with the quart containers, than toluene, or xlene, or avgas, or transporting race fuel...
the whole goal is to understand your net octane needs, and mix from there...I am not interested in paying more than I need to....atleast for fuel (and need to = what is the right thing, not interested in being cheap)
agreed. and if you buy it 5 gal. cans its cheaper, looks like its going for about $235 a can shipped now. thats $11.75 a qaurt. thats $1.17 added to your gallon of fuel cost, what ever it is at the time or area.
