2-Stroke
Aspen 2 Fuel
Premixed with fully synthetic, biodegradable oil suitable for engines requiring 50:1 or 40:1. Virtually no fumes or harmful components — especially important with hand-held equipment.
Better for man, machine, and environment. Aspen keeps 3–5 years vs. 3–5 months for ordinary fuel — and it's distributed in BC exclusively through Star West.
About Our Aspen Alkylate Fuel
Aspen Fuels are the preferred brand of performance fuels for emergency equipment and municipalities. A synthetic, Aspen fuel burns cleanly and does not “go bad” — it keeps your equipment running smoothly, keeps spark plugs and combustion chambers clean, and stays good for years without deterioration.
Two Engineered Fuels
Aspen 2 for 2-stroke engines — premixed with fully synthetic biodegradable oil (50:1 or 40:1). Aspen 4 for 4-stroke engines — a clean high-performance alternative to pump fuel that keeps generators and power equipment starting strong.

4-Stroke
Engineered for 4-stroke engines — a high-performance alternative to pump fuel. Works with generators and a wide range of power equipment. Less corrosion, less residue, cleaner engines.

Why Aspen
Low in olefins that contribute to ground-level ozone. Aspen 2T contains a biodegradable high-quality synthetic oil based on renewable content.
Virtually free from benzene, a cancer-causing compound found in ordinary gasoline. Respiratory issues, headaches, and toxicity are dramatically reduced.
Clean-burning fuel — your engine stays cleaner, lasts longer, and needs less maintenance. Can be left in the tank for years without fuel-system degradation.
Long-term gasoline-fume exposure causes serious health effects for crews using hedge trimmers, mowers, and chainsaws. Aspen is virtually free from benzene, aromatic hydrocarbons, and olefins.
Environmental Impact
40%
Less ground-level ozone
Reduces smog formation by roughly 40% vs. ordinary gasoline.
60%
Renewable content
The synthetic oil in Aspen 2 is up to 60% renewable.
80%+
Biodegradable in 28 days
The Aspen 2 oil biodegrades more than 80% within 28 days.
3–5 yr
Shelf life
Stays good for 3–5 years in storage — vs. 3–5 months for ordinary fuel.
The polyethylene plastic Aspen containers are selected with the environment in mind and can be recycled to produce materials and energy. When recycled, only carbon dioxide and water are produced.

The Story
Roland Elmäng founded the Aspen company in 1988 on the shore of Lake Aspen, north of Gothenburg in Sweden. The idea came after he read an article in the Swedish newspaper Skogen about the problems faced by forest workers exposed to exhaust fumes from chainsaws and brushcutters.
He realized there were fuel components that would work much better — both for people and machines. The introduction of alkylate fuel dramatically improved the working environment for Swedish forestry workers, and the formula has been refined for more than thirty years since.
