Is it true that supermarket petrol is of poorer quality, less refined, than filling-station fuels?
Answers:
I don't really know which is better. Anyway, you should definitely avoid buying petrol/diesel from stations that are having very few customers, especially during winter. Condensation appears if the temp difference is to high in the underground fuel tanks (some of the stations do have a solution for this problem). And yes, poor quality fuel can seriously damage your engine, especially if it has common rail or direct fuel injectors. If you have a carburetor you don't have to worry.add a little kerosene in the fuel tank and carry on driving!
Not true they usually by in bulk and get a discount or they use the price reduction as a loss leader.
Both the supermarket and petrol station get petrol from the same refinery.
A loss leader is when they discount a product to entice you into the supermarket so that you buy other things that are more expensive.
They buy it from the same refineries as they big guys, just don't advertise the name so they have the felxibility to buy from the lowest priced supplier.
you will find with supermarket petrol it has less additives so not as good quality as example B.P etc. We find that the m.p.g is better if bought from a filling station than from the supermarkets. Hope this helps.
No.it's brought in from the same refinieries. The reason it can be sold so cheap is because the supermarket makes most, if not all of it's money by selling groceries and can afford to have the cheapest gas in town.
This petrol may come from the same refineries, but can be processed differently, making it an inferior quality. In fact many petrol stations get their gas from the same refinery. example are Shell, Amaco, Caseys and B.P. all get there petrol out of the same refinery. Keep in mind, if a supermarket sold inferior gas, they would not be selling gas too long.
no, not at all
It's the same.
How long do you think Tesco, Sainsburys & co would last if their petrol/diesel was screwing up thier customer's cars.
