Heck, why not make it daily, or allow oil price wars as mentioned in The Will to Compete?
Dateline 2015-12-31, NST:
There will be a weekly fuel price revision if the government agrees with the idea mooted by the Petrol Dealers Association of Malaysia (PDAM).
Deputy Finance Minister Datuk Johari Abdul Ghani said the government was receptive to the idea, adding that PDAM was expected to submit a proposal to the ministry soon.
The retail fuel prices have been fixed on a managed float system since Dec 1 last year, where retail prices are based on the monthly average world price of crude oil.
