Frequently Asked Questions

Like most fuel brands, Circle K stations in Louisville adjust prices 1-3 times per week in response to wholesale cost changes. Prices typically move together across a brand's stations in a market area.
Most Circle K locations offer diesel fuel alongside regular and premium grades. Major Circle K stations in commercial and highway locations routinely stock diesel for trucks and commercial vehicles.
If Circle K's prices in Louisville are above your budget, consider Costco (cheapest member option), Circle K, Speedway, or QuikTrip for competitive pricing, and the Upside app for cashback at participating stations.
Using the correct grade of Circle K fuel for your vehicle will not meaningfully change fuel economy compared to other brands selling the same grade. Engine design and driving behavior have a far larger impact on MPG than fuel brand choice.
