A petrol investigation lead by the RACV has uncovered the best and worst places in Victoria to fill up your car.

RACV vehicle engineering manager Michael Case said that the survey “exploded the myth” that prices in the country were always more expensive than in the city.

“The difference between the suburban highest and lowest price is almost $5 per tank of fuel, and that can have a big impact on the annual household budget,” he said.

Mr Case said a main factor influencing fuel prices was competition, or a lack of it.

“In highly competitive local areas when one retailer cuts their prices other competitors follow.”

The survey found that the suburbs of Benalla (131.7c a litre) and Ballarat (137.5c a litre) were the cheapest in the entire state, and in Melbourne, the cheapest was found in Maidstone (137.9c), McKinnon (138.2c), Doveton (138.3c) and Wantirna (138.5c).

On the more expensive side, was the suburbs of Kingsville (146.5c), Ringwood East and Gardenvale (146.3c) and Hampton (146.1c).
