Every gallon of CountryMark 90 PLUS is refined to exceed customer expectations. Whether you've got a boat, 2-cycle engine or a seasonally driven vehicle, this ethanol-free fuel is easy on your engine and delivers the most efficient power – leading to more miles per gallon on the road and more hours per gallon for small engines.
Using ethanol-blended fuels to power boats, two-cycle engines or cars that are not driven regularly can damage the engine.
Ethanol, made from corn, has been combined with gasoline for years in a mixture of roughly 10 percent, which is also known as E10 gasoline. The larger engines in cars can tolerate this ratio. But in smaller engines, it can corrode metal parts, stiffen plastic and rubber in seals and tubing, and make starting harder. Ethanol is an alcohol that can draw water into the engine, which can compound potential for trouble.
Vehicles driven seasonally also benefit from ethanol-free fuel. This is because ethanol attracts water and holds it in suspension. Although the amount of water that can be drawn in from ethanol-blended fuel shouldn't be enough to cause performance issues, it is enough water that, when held in suspension for extended periods, can cause steel fuel lines and tanks to rust from the inside.
In addition to being ethanol free, CountryMark’s 90 PLUS gasoline also features a TOP TIER detergency package. Additional fuel detergency keeps engines running smoothly, improves engine performance and reduces vehicle emissions. The higher octane rating of 90 works hand-in-hand with the optimized detergency package to deliver a fuel that keeps engines running smoothly and more efficiently.
