Filling up the car will be less confusing under petrol price board reforms being considered by the Queensland government, the state's peak motoring body says.

The government plans to ban the display on fuel price boards of cheaper prices that are only available to motorists who have a discount voucher or make an in-store purchase.

The RACQ supports the move, saying it will bring Queensland into line with advertising standards in several other states.

"Current price boards displaying discounts are confusing and designed to lure motorists into service stations under the guise of lower prices," RACQ spokesman Paul Turner said.

"The regulation will even the playing field by forcing all retailers to advertise the true price. This will also allow motorists to make informed choices about where they want to fill up."

The proposed changes have been released for community and industry consultation, with the government expecting to sign off on them by the middle of the year.

Service station owners will then have six months to implement the changes from January next year.

Minister for Energy, Biofuels and Water Supply Mark Bailey said the new regulations were drafted following the Fuel Price Summit in 2016.

"Consensus at the summit was that the regulatory model in place in South Australia and Victoria is the preferred approach," he said.

"The new regulations the Palaszczuk government is proposing adopts this model."
