for the benefits of those who go jb pump petrol...
my personal experience:
half tank still pass custom check, as i did got check by custom officers when my needle is at half tank, he let me pass... so customs officers are quite reasonable...
usually at half tank i only pump abt 20L
once again, a call to all latios who pump petrol in jb, we can go in together, I live in bishan, so those nearby can go together... pump petrol, eat a bit supper, or go massage...
those interested can pm me, thx
