Siguraduhin mo lan na ung gas station ay hindi madumi ung gasoline nila (hindi binabaha, hindi hinahaluan ung tanke, etc.).

experience ko same brand, same type of gasoline, pag sa gas station A maganda performance, pag sa gas station B, poor performance. Kaya meron ako suking gas station, pag hindi maiwasan max na ung Php500 sa hindi suking gas station.
