I am actually pleased with the authorities planning to impose 3/4 fuel tank rule for diesel cars too. With so many private hire cars and also many rich cheapos driving diesel cars on the roads now, it's about time we do something like this, otherwise our checkpoints will be jammed like nobody's business.
I understand that there are ways to outdo it it to install a device in the car to ensure that fuel tank gauge only points to 3/4 mark and it's widely available in Malaysia. Please check on the spot when the car arrives at the
checkpoint and ban this device from being installed in Singapore registered cars, and if any cars were found to have that device installed, kindly impound the cars and make sure that device is removed before the car is
allowed to be in the roads and also fine the driver for that.
