MOTORING holidaymakers can save by filling up in some regional centres instead of Adelaide after the pricing cycle reaches a peak.
Unleaded fuel prices were cheaper yesterday at Clare and Murray Bridge than the average per litre in Adelaide, AdelaideNow reports.
Metropolitan prices jumped 20c a litre to 149.9c at the top of the cycle on Wednesday before easing back to 145.5c a litre yesterday.
The good news for city motorists is that fuel prices are expected to fall over the next 10 days.
But motorists heading to Melbourne today or tomorrow should consider filling up at Murray Bridge where prices have been averaging 141.5c a litre this week, said RAA senior policy analyst Chris West.
Clare prices yesterday were almost on par at 141.4c a litre - a saving of more than 4c a litre on the Adelaide average - because unlike the city, regional centres do not have a pricing discount cycle.
Unleaded fuel prices on Yorke Peninsula were also a "standout" at the moment and prices there were expected to stay in the low 140c a litre across the Christmas period, Mr West said.
"I would anticipate ULP (unleaded petrol) prices will be in the high 130c (a litre) range by Christmas Day (in Adelaide) and continue to fall over the next week and a half as part of the pricing cycle," Mr West said.
Regional prices are expected to "fall slightly because wholesale prices have been falling" and savings should be passed on to the pump, he said.
Mr West also advised drivers of diesel fuel vehicles heading to Victoria to fill up in South Australia.
Two Victorian refineries were damaged by storms earlier this month, which caused interruptions to diesel production.
The 20c a litre price spike in ULP on Wednesday represented the peak of the cycle and not a cash grab by retailers to coincide with the Christmas holiday season, according to Mr West.
He said fuel retailers were keen for motorists to spend money on other items, such as drinks and chocolates, in the store so it was unlikely owners would deter motorists during the high-demand summer holidays.
"History shows retailers are more behaved than ever," Mr West said.
"They want people spending in their store and the incentive for retailers is to put out the best petrol price they can."
