Cheaper?

Is it really much cheaper to pump petrol across the causeway? Tonight may be the second time that hubby going over to JB to top up petrol. He said that it is much cheaper and he may be able to save up till $25 per trip. But I’m still no sure how he did up the sums and plus I do not want to argue with him so just let things be lah..

But I really wonder, does it really helps in saving $? If the tank is not three quarter full, he still have to top up a little in Singapore, then go over to JB. And he may be lucky that he did not need to queue in both directions.. But he was half lucky the last round, he needs to queue for a while when he is coming back… Last round, he went in at 11 plus but he was only back round 1 plus.. He said that the queue was very long..

Hmm.. Let me go n do up the sums for him again and see if there are really some savings instead of making wasteful trips there.
