Get to know the prices in your area. Prices will rotate around the average by as much as 5
cent per litre, so its worth getting into the habit of noticing prices as you drive around. Always favour the garages with the cheapest fuel, rather than staying loyal to one outlet or one brand.
Buy petrol in units of litres rather than in units of pounds. Most people buy
€10 or €20 or just fill up - this disguises the value that you are getting. If you always buy 30 litres of petrol rather than
€20 worth, it becomes very obvious when one garage charges
€26.70 (89 cent per litre) and another charges €29.70
(99 cent per litre) for the same amount of fuel.
Ignore loyalty schemes, bonus schemes etc and just concentrate on price.
Use fuel wisely. Your driving style will greatly affect your fuel consumption. Drive gently, avoiding harsh
acceleration and braking. Roofracks add to fuel consumption so remove them when not in use. Air conditioning - standard now on more and more cars - adds greatly to fuel use, so turn it off when you don't really need it.
