Aspen

Aspen is a leading brand of engineered alkylate fuel, known for providing cleaner, more efficient fuel options for outdoor power equipment. Developed in Sweden over 30 years ago, Aspen offers products like Aspen 2 and Aspen 4, which are designed for use in 2-stroke and 4-stroke engines, respectively. These fuels are free from ethanol, reducing corrosion and engine deposits, while also being more stable for long-term storage—lasting up to five years when sealed properly. Aspen fuels are widely trusted in industries such as landscaping, forestry, and motorsports for their superior performance and environmental benefits.
