What if you recycle all those oil bottles and buy more gas when prices are low? Whenever you top up, you could also fill those bottles. You could label them with the prices you paid and keep it in an open or ventilated room. A dry powder extinguisher located close by.

You could either monitor WTI prices or use whatever app available to predict the next oil price.

Instead of relying for pump prices, you could use up your stock when prices hit high. Or at least paying less than what you could have. This is what oil traders do. They either own or lease huge tank farms to fill up with crude and sell at higher prices. This could also mean less trips to gas stations.
