New study: Monday is the best day to buy gas
However, the best day can vary depending on where you live:
- In 2017 so far, Monday is the best day of the week in 23 states.
- In 2016, Monday was the day featuring the lowest average gasoline prices in 36 states, while Tuesday was the lowest in eight states.
- In 2015, Monday saw the lowest gasoline prices in 22 states.
- In 2014, Wednesday was the day of the week offering the lowest average gasoline prices.
Thursday, on the other hand, is the worst day of the week to buy gas, the study found.
“The rise in average prices towards the weekend could be to blame on an influential report from the Energy Information Administration (EIA) issued weekly on Wednesdays, which could push prices higher the day after, depending on if data in its report is as expected or a surprise,” said Patrick DeHaan, senior petroleum analyst at GasBuddy. “Since commodities trading isn’t active over the weekend, it typically allows stations to ‘let it ride’ over the weekend, culminating in lower prices by the start of the work week.”
For some perspective, if every U.S. driver bought gasoline only on Thursday for an entire year, they’d collectively spend an extra $1.1 billion, compared to filling up on Monday, according to GasBuddy.
By comparing prices and using gas price data like this, GasBuddy said drivers can save an average of $325 a year.
But don’t just fill up at any gas station! Buying gas from a station on this list, which includes Costco Wholesale and QuickTrip, can be better for your car.
