Gas Buddy has released its new analysis identifying the cheapest and most expensive days of the week to buy gasoline in all 50 states.  Based on an analysis of daily statewide fuel prices over the past year, Gas Buddy found that Sunday is the most consistently affordable day to fill up in most states.  Midweek, especially Wednesday through Friday, tends to be more expensive.

In most states, prices gradually rise through the week before easing into the weekend.  Buying on the lowest-priced weekday instead of the most expensive one can save drivers four to nine cents per gallon.

Gas Buddy says, here in Minnesota, Sunday is the best day for you to fill up, while Thursday is the day you should avoid.

LOOK: See how much gasoline cost the year you started driving

To find out more about how has the price of gas changed throughout the years, Stacker ran the numbers on the cost of a gallon of gasoline for each of the last 84 years. Using data from the Bureau of Labor Statistics (released in April 2020), we analyzed the average price for a gallon of unleaded regular gasoline from 1976 to 2020 along with the Consumer Price Index (CPI) for unleaded regular gasoline from 1937 to 1976, including the absolute and inflation-adjusted prices for each year.

Read on to explore the cost of gas over time and rediscover just how much a gallon was when you first started driving.
