WEST MICHIGAN -- As the months grow warmer, travel out on the roads picks up for a lot of West Michigan families. If you are someone that fills up regularly, or have a long trip ahead of you, the day you choose to go to the station can save you money.

Michiganders typically knock out filling up their tanks right before the weekend. If you want to save a few bucks, you may want to stretch what you have left until the weekend is done.

According to a study done by, the best day to fill-up in the state is Monday. More specifically, Monday morning before 9:00 a.m.. They collected data through their app from January to March of this year, finding, oddly enough, that most people fill up towards the end of the work week when prices are usually the highest.

Both energy market movement during the week and government reports on fuel pricing, which comes out on Wednesdays, tend to drive the price up by Thursday or Friday.

Theoretically, if all Americans filled up on Monday, the difference would be about $2 billion over the course of the year, says Patrick DeHaan of GasBuddy.

Prices usually start to drop over the weekend, bottoming out Sunday night or Monday morning. Energy prices stabilize late Friday as markets are closed over the weekend. If you can switch when you fill up from late in the week to Monday morning, you will likely save yourself time and money at the pump.
