I once had a conversation with a guy that fitted LPG to cars for a living I remember him telling me that automotive LPG (liquid propane gas) is propane with stuff added to meet legal reqirements and to make it better for automotive application. He said they add some smelly stuff (by law) to make it safer because propane is odourless, and they add some other things like butane to stabalise it because straight propane is too easily affected by temperature so unless it is filled in a controlled temperature environment each fill could have a differerent true volume at a given temperature. I would have though that there is no advantage using straight industrial propane other than that industrial propane is probably a bit cheaper than automotive LPG.
Are there any experts on line that know about this ??
Filled up my car from the forklift tank at work a few times and the only difference to the stuff you get from the servo was the price.............FREE.. hehehe
Never noticed a performance difference between the two.
Even used to fill up the BBQ bottle when the boss wasn't looking.
