Timing Your Gas Fills Can Save You Money

Experts say patience and a little timing could pay off at the pump

Published on Feb. 27, 2026

According to GasBuddy's analysis of gas price patterns, the beginning of the week, especially Sundays and Mondays, is statistically when drivers can find the best gas prices, often 4 to 9 cents per gallon less than midweek. In some states like Michigan, Indiana, Ohio, Florida, and Texas, gas prices follow a predictable weekly cycle, spiking midweek and then dropping again by the weekend, allowing drivers to save 15 to 45 cents per gallon by timing their fill-ups.

Why it matters

With gas prices remaining high, finding ways for drivers to save money at the pump is important. This analysis provides a simple strategy that many consumers can use to reduce their fuel costs.

The details

GasBuddy, which tracks prices at over 150,000 gas stations nationwide, found that gas prices start low on Sundays and Mondays, then rise through the middle of the week, peaking on Wednesday through Friday, before dropping again by the weekend. This pattern is especially pronounced in certain Midwest and Southern states that experience 'price cycling', where prices gradually increase until a sudden spike, then fall back down. The best savings often come 5-7 days after a price jump, with the gap between peak and trough prices reaching 15-45 cents per gallon.
