On T-Mobile Tuesdays, T-Mobile customers save big on gas.

The Fuel Rewards program and Shell are adding 25-cent-per-gallon discounts on gas purchases to the list of gifts that millions of T-Mobile customers can get each week through the T-Mobile Tuesday app.

T-Mobile’s 67.4 million U.S. customers can use the “T-Mobile Tuesdays” app each week to receive free gifts and discounts on food, movies and gas. The 25-cent-per-gallon Fuel Rewards discount code is a part of the rotation of weekly offers.

Through T-Mobile Tuesdays, T-Mobile offers customers the same fuel-saving currency that has found success in the grocery, dining, travel and retail sectors and that also ranks highly among U.S. consumers as a preferred loyalty program currency capable of delivering recurring, everyday value.

Once the Fuel Rewards discount code is activated, T-Mobile Tuesdays users can redeem their 25-cent-per-gallon savings at participating Shell stations from coast to coast. Joining the Fuel Rewards program to redeem the discount is easy and offers even more opportunities for T-Mobile customers to save on one of their everyday expenses — the cost of fuel.

Since its launch in 2012, Excentus’ Fuel Rewards program’s 8 million members have saved more than $850 million collectively on fuel by earning rewards at participating retailers, restaurants, online merchants and convenience stores nationwide. Rewards are redeemed as cents-off-per-gallon savings at the pump.

“We’re pleased to be able to bring easy everyday savings to T-Mobile Tuesdays members,” said Jeffrey Hassman, chief marketing officer of Excentus, the Dallas-based loyalty program technology and solutions provider that manages the Fuel Rewards program. “They love the ability to enjoy discounts on fuel, one of their most frequent purchases.”

Shell Oil Co. is an affiliate of the Royal Dutch Shell plc, a global group of energy and petrochemical companies with operations in more than 70 countries. In the U.S., Shell operates in 50 states and employs more than 20,000.
