Whenever I visit a petrol station to pump petrol for my car, I always opt for the ‘regular’ petrol (green pump) not those with extra mileage & stuff like that (red pump). Most of the time I will look out for the green pumps & start to fuel. However, I have noticed a few times that the green pump is for the special petrol which is slightly more expensive and not the regular petrol. I was wondering if there is any sort of regulations or control on which colour represents what type of petrol. I think some petrol stations are using this tactic to make consumers pay for the more expensive petrol.
