Malaysia's subsidised petrol price has not moved once since the day it launched. In the same 49 weeks, the price everyone else pays changed 32 times. The result is that the 300-litre monthly cap on the subsidy, a rule nobody has altered, now costs almost three times what it did to cross.

Forty-nine weeks, one price
BUDI MADANI RON95, or BUDI95, began on 30 September 2025 at RM1.99 a litre, down from RM2.05. The Finance Ministry says it covers Malaysians aged 16 and above holding a MyKad and a valid driving licence, for up to 300 litres a month, and reported more than 13 million users and about RM800 million in savings in its first month alone.
We pulled every weekly fuel price the government has published since March 2017 and filtered to the BUDI95 period. Across all 49 weekly prints, the subsidised price reads RM1.99 every single time. Not one adjustment.
The unsubsidised RON95 price over those same weeks is a different picture entirely. It changed 32 times, ranging from RM2.52 to RM4.27, and sits at RM3.77 in the week of 3 September 2026.
The gap did the moving
Because one line is frozen and the other is not, the distance between them is where the story is.
- When BUDI95 started, the two prices were 61 sen a litre apart.
- They are now RM1.78 apart, and the widest gap recorded in the period was RM2.28.
On a 40-litre fill that is the difference between RM79.60 and RM150.80, a gap of RM71.20 for the same tank of the same fuel.
What this quietly did to the 300-litre cap
This is the part worth knowing, because no rule changed and no announcement was made.
The subsidy stops at 300 litres a month. Beyond that, a driver pays the unsubsidised price. At launch, going 50 litres over the cap cost about RM30 extra. Today the same 50 litres costs about RM89.
Nothing about the cap moved. The penalty for crossing it grew on its own, because it was never a fixed amount, it was always the gap, and the gap has widened. Anyone who set their driving habits against the cap in October 2025 is now facing a meaningfully different number for identical behaviour.
At roughly 40 litres a week, most drivers sit around 170 litres a month and stay well inside the cap. The people it reaches are the ones who drive for a living or commute long distances, which is why full-time e-hailing drivers were exempted from the ceiling from 15 October 2025 and can apply for additional allocation.
The same pattern is bigger in diesel
Diesel shows the effect more sharply still. Peninsular Malaysia's diesel is RM4.67 a litre this week, while Sabah and Sarawak pay RM2.15. That is a RM2.52 difference for the same fuel in the same country.
When BUDI95 began, that east-west diesel gap was 78 sen. It has widened by more than three times, and reached RM4.57 at its peak.
Why we are reading the price series rather than the announcements
A subsidy that never changes its number looks like nothing is happening, which is exactly why it goes unreported. The movement is in what it is being measured against, and that only appears when you line up every weekly print side by side.
All figures here come from the Malaysian government's own weekly fuel price series on data.gov.my, covering 477 weeks from March 2017 to 3 September 2026, and from the Ministry of Finance's published statements on the BUDI95 programme. Prices are for the week of 3 September 2026 and change weekly.
