If you’re considering a Marathon fuel card or already using one and exploring other options, it’s worth comparing it with other fleet cards. The Marathon fuel card is issued by WEX and offers fuel discounts at 6,000 Marathon locations, with acceptance at 95% of fuel stations nationwide through the WEX network.
Marathon can be a good fit for businesses that frequently fuel at Marathon stations, but other cards may offer broader acceptance, discounts across more fuel brands, or fewer fees.
In this guide, we highlight five Marathon fleet fuel card alternatives and compare their discounts, fees, and acceptance networks so you can find the best fit for your business.
