Petrol stations will be banned from advertising discounted fuel prices on their display boards, under new regulations to be introduced by the Victorian government later this year.

This will force petrol stations to show the full un-discounted price of fuels on the large boards advertising the current fuel price.

Until now fuel boards have enticed motorists by displaying a price that was 4¢ below the pump price, mostly at Shell Petrol stations linked to Coles Supermarkets and Caltex petrol stations linked to Woolworths. This price was only available if motorists had a valid discount voucher.

The government was now "cracking down on misleading fuel boards right across Victoria," Minister for Consumer Affairs Jane Garrett said on Sunday.
