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

If calculating 23/7 to 29/7 cycle (Thursday to Wednesday - weekends are using Friday prices), the actual retail price for RON95 & RON97 should be RM1.60 and RM1.90 respectively (±1 sen).

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

For the past few weeks, the government has applied a hidden tax of approximately 8-9 sen. Thus, I estimate that RON95 and RON97 will be unchanged from last week at RM1.68 and RM1.98 respectively
