APEX

Sunoco APEX is a 95 octane unleaded racing fuel that complies with fuel regulations limiting oxygen content to 2.7 weight %.  The properties of APEX were carefully tailored to allow small bore high revving engines to achieve peak performance while maintaining compliance with FIM Superbike Fuel Rules.

Although APEX is not a street-legal fuel and is for off-road and racing use only, it will not harm oxygen sensors and catalytic converters and works fine in fuel injected race engines.

Sunoco APEX contains additives to enhance shelf life and promote engine cleanliness. As with any gasoline, it should be stored in opaque, tightly sealed containers and kept where temperatures are stable. Properly stored, the shelf life of APEX is one to two years.
