Consumer usage plays a role, too — and weekend demand is high, says Jason Toews, co-founder of, a price-monitoring site. Prices usually swing upward on Thursdays as travelers fuel up to head out the following day. By hitting the pump before 10 a.m. (when many station owners change their prices), you'll beat the rush and the price jump.
