no my greenhouse heater uses gas and that comes in a big red bottle. i have to buy my petrol from a petrol station and its a liquid so its not the same

oh! so they relie on nothing but compression to ignitr them?? wow! they must have some presser in there for them to do that. so what about this gas does that burn under pressure too??

so it runs on gas? can i use the gas bottle from my greenhouse heater or is it special gas? and what about the sparkplugs? are they the same as the desiel ones? sorry for all the question but i'm a bit thick when it comes to cars and the like.
