The 20-litre fuel cap on foreign vehicles travelling within a 50km radius from the border will be implemented tomorrow, Domestic Trade, Cooperatives and Consumerism Minister Ismail Sabri Yaakob said.

He said the ruling was aimed at checking smuggling of petrol and diesel at border areas until a new mechanism on fuel subsidy was implemented in May next year.

"Petrol kiosks at border areas have been given notices informing them of the new ruling on foreign vehicles," he told reporters at parliament lobby here today.

Singapore vehicles returning home should have more than 20 litres as it has a three quarter tank policy while those entering Malaysia could only fill up 20 litres.

Ismail said the ministry would be stationing officers at 493 petrol kiosks at border areas to ensure that operators adhere to the 20-litre ruling.

"Our officers will be equipped with charts on fuel capacity according to vehicles. For example, Toyota Camry with 20 litre will fill one quarter tank, Nissan Sentra and Honda Civic about one third tank," he added.

Under the Supply Control Act 1974, offenders can be fined RM100,000 or three years' jail or both while kiosk operators can be fined RM250,000 and the licence revoked.
