The cost of driving fell again Thursday across most of Newfoundland and Labrador, as the province's fuels regulator instructed service stations to cut their prices.

The PUB lowered the ceiling on gas prices by as much as 4.3 cents per litre. The change varies slightly in some geographic pricing zones because of rounding for taxes.

The new price setting is the latest drop in a slide that started in mid-November.

The change means that the maximum price for a litre of self-serve unleaded gas on the Avalon Peninsula is now $1.237. Some retailers charge considerably less.

Meanwhile, diesel costs were lowered by as much as 3.2 cents per litre.

Home-heating fuel also got cheaper, with furnace oil dropping by 3.2 cents per litre. Stove oil dropped by 3.11 cents per litre.

The cost of propane, though, did not change.

The chart below shows how average gas prices in Newfoundland and Labrador have changed over the last 12 months, compared to changes in the national average for gas prices as well as the global price of oil.
