Aspen 4 4-Stroke Alkylate Petrol – 1L

Aspen 4 is fuel for 4-stroke petrol machinery such as lawnmowers, cultivators, generators and snow blowers. It contains no added oil and is used in the petrol tank while the engine's lubrication is maintained separately.

What is Aspen fuel?

Aspen is a specialist alkylate petrol developed for small engines. Its carefully controlled composition contains far fewer harmful components, such as benzene and aromatic hydrocarbons, than ordinary pump petrol. It is also ethanol-free. This makes it a useful choice for machinery used close to the operator and equipment that spends weeks or months between jobs.

Key benefits

• Cleaner exhaust: reduces exposure to several harmful substances found in the exhaust from conventional petrol. Engines must still be operated outdoors.
• Cleaner engine: helps limit deposits on spark plugs and in the combustion chamber, supporting reliable running.
• No ethanol: avoids ethanol-related moisture absorption and associated fuel-system problems.
• Long storage life: Aspen quotes 3–5 years under suitable storage conditions, making it practical for seasonal machinery and helping with starting after storage.
• Convenient refuelling: supplied ready to use in compatible 4-stroke petrol engines without adding 2-stroke oil.

Why choose it?

A practical option for mowers and other machinery used seasonally, where stale pump petrol can contribute to poor starting and maintenance problems. Its higher purchase price reflects the specialist fuel formulation; the benefits are convenience, storage stability and reduced deposits rather than a promise of lower fuel consumption.

How to use

Check your machine's fuel requirements, then fill its petrol tank with Aspen 4. Maintain the separate engine oil level as instructed. Do not use it neat in a 2-stroke engine that requires oil mixed into the fuel. Stop the engine and let it cool before refuelling. Follow the machine manufacturer's instructions when changing fuels and storing equipment.

Safety and storage

Highly flammable petrol. Keep away from heat, sparks and flames. Use petrol machinery outdoors only; cleaner fuel does not make exhaust safe to breathe. Store upright in the original, tightly closed container in a suitable cool, ventilated place, out of reach of children. Read the container label and safety data sheet before use.
