Which petrol station? And really got petrol station so stupid do this kind of thing meh? Confirm very easy to kena tangkap one.
Likely unintentional from compromised underground tank, since says there station is closed afterwards for maintenance. That + lots of groundwater in rainy season.
If confirm unintentional and car got issue, can claim insurance?
Should definitely be able to seek compensation / saman petrol station for maintenance negligence at the very least.
Not sure what kind of technology in use we have in Malaysia to detect if tank is leaking or not. Here at 2:20 says newer tanks come with double-wall design to detect inner / outer wall leaks.
