Optima

Looking for a great vehicle storage and small equipment fuel?

Look no further. With Sunoco Optima, you can run it in summer and store it in winter… all with one fuel!

Sunoco Optima is an unleaded fuel blended from highly-refined hydrocarbon blendstocks. Optima does not contain ethanol or MTBE and is oxygenate-free. Optima has excellent storage characteristics, making it ideal for storing vehicles and gasoline-powered equipment, especially those requiring an exceptionally stable unleaded fuel.

Optima is specially formulated to be easy on gaskets, o-rings, and other fuel system components. It also promotes quick mixing with 2-stroke oils in both air-cooled and water-cooled applications. Sunoco Optima is an excellent choice for gasoline-powered yard, farm, and industrial equipment and other small engine applications that may not be used on a regular basis. Gasoline stabilizers are not needed when using Sunoco Optima.

Sunoco Optima contains detergent additives for engine cleanliness as well as anti-oxidants and corrosion inhibitors to enhance storage life. Optima is not a street-legal fuel and is for off-road and racing use only. However, it will not harm oxygen sensors or catalytic converters. When stored in air-tight, opaque fuel containers, the shelf life of Sunoco Optima is in excess of three years.
