PLUS Gasoline - Quality Fuels - Quality Performance

 
If you're looking for optimal gas mileage and engine performance, look no farther than CountryMark's lineup of American-made 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.
 
CountryMark PLUS gasoline is refined to the highest of industry 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.

 

For 2001 and newer passenger vehicles, CountryMark offers an 88 octane PLUS gasoline with a 15% ethanol blend. CountryMark 88 PLUS is a top tier certified gasoline. 


CountryMark also makes available a 90 octane product. This mid-grade fuel is TOP TIER certified and ethanol free, making it a superior fuel choice for boats, outdoor power equipment and high performance engines. 

For Flex Fuel Vehicle owners, CountryMark offers E85.
