About 1980 , in Canada there was an incentive to buy Propane Powered Vehicles.
Heck Gas was about $1.20 per Imperial Gallon Nd Propane was about .30 cents.
It made perfect sense ,until the Tax Man got wind of the situation. Propane shot upon in cost to almost the same level as regular gas! Killed the Industry overnight!
The difference in power between Propane and Gas isn't a big deal during normal driving ! Propane however burned cleaner and Oil Changes became less frequent..Engines lasted longer and the Air We breathe was a little bit cleaner.
So what killed it?
Government..Yours and Mine!
Greedy bunch of hypocrites !
