Good to know.
I do have a car that runs off of a 'similar' gas. You could say the car is a "hybrid." It runs off of gasoline and a 'funny' cylinder of compressed gas .....It is one of the most efficient cars on the road....yes I can/do drive this wonder on the road.
While other "hybrids" struggle to burn one gallon of gasoline in 30 miles, mine can burn a gallon of 93 octane in about 7.5 miles in the city....though, it does get about 8 mpg on the highway. What could be more efficient in burning gasoline faster than that?
And for those that need to get that first 1/4 mile under their belt in a hurry - it has a cylinder of funny gas in the trunk; so funny some call it "laughing gas."
Although this costs slightly more than $1 a gallon.
But, just so no one gets upset....I do care about the environment. Which, is why I didn't want to use up rare earth metals like platinum if I didn't have to; ie no catalytic converters for me.
I know a guy back in the eighties who had a nitrous oxide tank in his souped up Trans Am. Fun Car.
