kinda in away but it would really just be wasting your time. this is why i say that. A fuel's resistance to detionation is known as its octane rating. the octane rating is the primary benefit of racing fuels, in addition the energy contained per unit is more consistent, so jetting/injector duty cycles and other tuning measures are more predictable. Gasoline in general, both pump gas and racing, has about 20,000 British thermal units (BTU) per pound. the BTU content of a fuel is a measure of the potential heat a given unit of fuel can produce.Racing gas, because they are blended with less of the light ends that make for easy starting, have slightly more BTU than pump gas, but if you dont have the compression ratio of like 14:1 you will be just spending money you could have spent somewhere else.But you sure wont have to worry about detonation.[/
