Gasul’s hotline is 7378000. When I ordered a few days ago, I was asked if I had a Petron value card. Husband did and so, as requested, I gave the number to the order taker. This entitled me to a P10 discount on my 11kg de salpak order.
Incidentally, where before petron gas stations would asked if one had an SM advantage or BDO Rewards card so one could gain points for gassing up with Petron, starting 31 August, only Petron value cards will be blessed.
