LOL, all countries are like this because not everyone wants be an engineer.

I'm an engineer. I used to look at dynamic raster images on a phosphorus coated screen excited by accelerated electrons organized and guided in scan lines by a special electromagnetic steering mechanism while under vacuum. Other people watched TV.

You might not believe it, but liquefied petroleum gas is as technical a term as the word pizza. Everyone understands what it is to a certain level, but it is itself not an actual technical descriptor of what you got in your metal tank. You can have a 5 gallon tank of propane at 300PSIA and you'd have a scientific descriptor of what the stuff inside is.

Finally, gas, liquid or solid, they are all fuels. In America, the qoloquial term in the California, Oregon and Washington state areas (west coast) is gas, short for the trademark "gasoline" as opposed to referring to the fuel's matter state. In other places people refer to it as petroleum, petrol, fuel. In Mexico there are various fuels for sale at the pump... There is petroleo, which is liquid but is neither gasoline nor diesel but something in between, there's gasolina and disel. Gasoline in Mexico will have funny terms like magnazin...well WTF does that mean? Do they put magnesium in it? Is it synthetic? No clue, but there you are. If you want to, you can find out simply by searching for that information... Formally referred to as "googling it", which is another non scientific, meaningless term. I've gone back to "searching the web" because Google is now an evil company.
