a place to buy gasoline is called a 'gas station'

But here in the UK I buy GAS for my caravan to heat my food on my gas cooker. And I use GAS at home for my Central Heating

I buy PETROL (From PETROLeum) for my car from a petrol station. You can buy GAS for your car at some, but it's LPG (Liquified PETROLeum GAS). The dual use of the word gas in the USA has confused me at times.
