now its appears to me they operate like some kind of delayed price adjustment...to minimize impact

At shell, what is RON100 called? Im a bit confused. Want to try the RON100 but they have Vpower  (red color, not sure RACING variant or not) for RM2.60/L

If it isn't RON100 why is it so expensive compare to regular RON97?

Additives does not give it color. Color is caused by dye. Dye is used to help visual differentiation

Calculation and table of estimated prices can be found at this link: https://goo.gl/cpYiBN

If calculating 26/11 to 2/12 cycle (Thursday to Wednesday - weekends are using Friday prices), the actual retail price for RON95 & RON97 should be RM1.65 and RM1.95 respectively (±1 sen).

If we follow the Automatic Pricing Mechanism and Sales Tax Act, the government is allowed to "tax" us higher by 60sen per litre for petrol products sold.

Normally, the government applied a hidden tax of approximately 8 sen. Thus, I estimate that RON95 and RON97 would increase by 6 sen from last week to RM1.73 and RM2.03 respectively (±1 sen).

Just before the MCO, indication is that the fuel price will go up this Saturday by 8 sen (as of 11/1). For those that are not WFH / working in essential sectors, do fuel up before Saturday. https://goo.gl/cpYiBN

What do you think is the reasoning behind the change of cut off day?

It's basic extrapolation which is by no means accurate.

But looking at the rate of consumption and the last estimated figure for available reserves, we can infer 3 scenarios.

-consumption grows linearly (simplistic but capture the trend to a limited extent)
-consumption growth remain stagnant as per last record (highly unlikely)
-use average consumption data throughout the period and calculate the reserve from there (not really good for anything, i guess)

These figures are always subject to change depending on the newly discovered reserve, or new data on energy consumption for the latest year. Our oil export is partly from our own reserves, and partly re-export from other countries. So we do actually touch our reserves.

And yes we do import refined oil. From Singapore, because the capacity to refine crude oil to finished product isn't enough for domestic consumption. At least RAPID completion helps a bit with that. But for good while in the last decade, a significant portion of refined petroleum product (gasoline and all) was imported from Singapore.

If you're curious on further info, maybe you can check out the United Nations COMTRADE statistics for data on export and import destinations & volume of our crude oil (HS Code 2709) as well as refined oil though (HS Code 2710)

I don't understand why government still need to control ron97 price.

LOL! Finally after artificially controlling the price

Calculation and table of estimated prices can be found at this link: https://goo.gl/cpYiBN. No guarantees any of the estimates will be correct as the government has been heavily subsidizing the fuel price - even RON97! The good news is that RON95/Diesel has hit the ceiling and will continue on to be RM2.05 & RM2.15 respectively for the foreseeable future.

If calculating 26/10 to 1/11 cycle (Tuesday to Monday - weekends are using Friday prices), the actual retail price for RON95 & RON97 should be RM3.06 and RM3.36 respectively (±1 sen) - the subsidy amount of RON95 has finally reached more than RM1 per litre.

Thus, I estimate that RON97 would go up by 10 sen from last week to RM3.07 (±1 sen).

Note: RON95 will be capped at RM2.05/l & Diesel at RM2.15/l source

If RON97 is RM5, u think govt will keep RON95 or diesel at current prices?

If calculating 22/2 to 28/2 cycle (Tuesday to Monday - weekends are using Friday prices), the actual retail price for RON95 & RON97 should be RM3.41 and RM3.71 respectively (±1 sen).

Thus, I estimate that RON97 would go up by 9 sen from last week to RM3.38 (±1 sen).

Note: RON95 will be capped at RM2.05/l & Diesel at RM2.15/l source

One word: DIE
