Express Mart

Petr-All Petroleum Corp. owns and operates 70 Express Mart convenience stores, all located in upstate New York and all selling fuel. Most are branded Sunoco, some fly the Mobil brand and a few are unbranded. Eighteen of the stores feature a car wash. More than a dozen Express Mart locations are co-branded with McDonald's, Subway, Papa John's and Tim Hortons.

The stores were opened in 1989 to serve customers and meet their fuel and convenience needs. The target market is the suburban family and worker, who have the need for a quick stop for gas and/or a snack or grocery item. The stores pride themselves on offering "Around the Clock Convenience," a slogan they are known for. Many stores are open 24 hours a day, seven days a week.
