How much profit do service stations make on a gallon of gas?

Service stations typically make a small profit on a gallon of gas, often ranging from 5 to 15 cents per gallon. This margin can vary based on factors like location, competition, and market conditions. Additionally, many gas stations rely on ancillary sales, such as convenience store items and car washes, to boost their overall profitability. Consequently, the profit from fuel sales alone is often not the primary revenue source for these businesses.
