I'm not good at predicting the price of gas, however, I've been able to save money by buying based on the trends.
It seems contradictory to me, but what has worked is:
If the price trend is going up, fill the tank.
If the trend is downward, only partially fill.
I don't always hit the lowest price, but it has averaged that I buy at a lower price than when I try to guess future prices.
