PLUS Gasoline - Quality Fuels - Quality Performance

If you're looking for optimal gas mileage and engine performance, look no farther than CountryMark's line of all-American PLUS gasolines! All of the gasolines in the CountryMark PLUS line meet TOP TIER standards, which keep engines running smoothly, improve engine performance and reduce vehicle emissions.
These 100% American-made gasoline products begin with American crude oil and are refined to the highest specifications at the CountryMark refinery in Mt. Vernon, Indiana.
For fast starts, quick warm-ups and less vapor lock, all CountryMark gasolines are seasonally blended.

For different vehicle requirements, CountryMark PLUS gasolines come in various octane grades, including regular (87 octane), mid-grade (89 octane), and premium (93 octane). These products are TOP TIER certified, and oxygenated with a 10% ethanol blend, which increases octane, improves engine performance and reduces exhaust emissions.

CountryMark also makes available a 91 octane product. This mid-grade fuel is TOP TIER certified and ethanol free.

For Flex Fuel Vehicle owners CountryMark offers E85.
