After drifting down for a few weeks, gas prices took a costlier turn on Thursday for Newfoundland and Labrador drivers.

The Public Utilities Board allowed retailers to hike their prices by as much as 1.8 cents per litre.

That means a service station on the Avalon Peninsula, where gas prices are cheapest, can now charge $1.405 for every litre of self-serve unleaded gas that it sells.

The PUB also lifted the ceiling on diesel fuel by as much as 1.1 cents per litre.

Furnace oil and stove oil are both up by 0.77 cents per litre. Propane fuel for heating dropped by 0.8 cents per litre.

The Public Utilities Board, which has been regulating gas and other fuels since 2001, sets its prices every Thursday.
