Drivers are being urged to make a stop at the bowsers with a petrol price hike looming.

The cost of fuel could jump as much as 50 cents per litre across the country in the coming days.

The forecasted hike follows a large disparity at service stations in each city, with smaller petrol stations expected to bump up their price to meet those charging more.

As of Tuesday morning in Sydney, the cheapest petrol is $1.24 a litre, with the highest at $1.74.

In Melbourne, the cheapest is $1.27 and the most expensive also $1.74.

Up north in Brisbane, the cheapest is $1.27 and the priciest $1.76.

The advice is to shop around.

“There’s a growing number of independents in Sydney, which means you’re going to get more competition on price,” NRMA spokesman Peter Khoury says.

The massive gap in price, he says, is due to varying strategy by service stations.

Some prioritise profit margins, meaning they set higher prices, while cheaper petrol stations prioritise price competitiveness.
