The Benefits of Using Aspen Fuel for Your Petrol-Powered Machinery

Using the right fuel can make a significant difference in how your petrol-powered machinery performs and lasts. Aspen fuel, a type of alkylate petrol, offers a cleaner, more reliable option compared to standard pump petrol. This post explores why choosing Aspen fuel can protect your engine, improve performance, and save you time and money in the long run.

What Makes Aspen Fuel Different?
Aspen fuel is an alkylate petrol, which means it is a very pure form of petrol. Unlike regular pump petrol, Aspen contains no ethanol. Ethanol is commonly added to UK pump fuel, but has some drawbacks:
Ethanol absorbs moisture from the air (Hydroscopic), which can cause corrosion in fuel system components.
It can lead to poor engine running and increased maintenance.
Pump petrol often contains additives that cause it to go stale quickly.
Aspen fuel avoids these issues because it contains no ethanol and fewer additives. This purity allows Aspen to stay fresh for up to five years, making it ideal for machinery that is used seasonally or stored for long periods.
Examples of carburettors damaged by petrol going stale. In some cases, a new carb is the only remedy as the fine drillings get so blocked that they can't be fully cleaned out.
How Aspen Fuel Protects Your Engine
Using Aspen fuel helps your engine run cleaner. Cleaner running means fewer harmful deposits build up inside the engine and fuel system. These deposits can cause blockages, reduce efficiency, and lead to costly repairs.
With Aspen fuel, you can expect:
Reduced engine deposits that keep fuel lines, carburettors, and injectors cleaner.
Less corrosion from moisture, thanks to the absence of ethanol.
Smoother engine running and easier starting, especially after storage.
This protection often results in longer engine life and fewer breakdowns.
Improved Performance and Efficiency
Many users report that machinery running on Aspen fuel delivers better performance. This includes:
Longer run times per tank because Aspen burns more efficiently.
More consistent power output, which helps machinery work harder and more reliably.
Reduced risk of engine stalling or hesitation during use.
For example, gardeners and landscapers who switch to Aspen fuel often notice their petrol-powered tools run longer without refuelling and maintain power even under heavy workloads.
Aspen Fuel’s Long Shelf Life Saves Time and Money
One of the biggest advantages of Aspen fuel is its long shelf life. Standard pump petrol can start to degrade and go stale within a few months. This can cause:
Running problems such as rough idling or stalling.
Blocked fuel filters and carburettors.
The need to drain and replace old fuel regularly.
Aspen fuel stays fresh for up to five years, which means you can store it safely without worrying about it going bad. This is especially useful for:
Seasonal machinery like lawn mowers, chainsaws, and garden tractors.
Emergency generators that may sit unused for long periods.
Businesses that want to keep machines ready for use without frequent fuel changes.
Why ATS Machinery Ltd Chooses Aspen Fuel
At ATS Machinery Ltd, all new machines are run on alkylate fuel from the start. We have not kept standard pump petrol on-site for years. This approach allows us to:
Test and prepare machines well in advance of sale.
Ensure machines are ready for immediate use when customers need them.
Avoid fuel-related problems that can delay deliveries.
This practice highlights the reliability and quality benefits of Aspen fuel in real-world machinery use.
Aspen Availability
Aspen is available in several container sizes and in a pre-mixed 50:1 suitable for most 2-stroke engines (ASPEN 2) & a neat version suitable for 4-stroke engines (ASPEN 4).
Also, we are able to offer Aspen in bulk. Please talk to our sales team for information or to place an order.
Practical Tips for Using Aspen Fuel
To get the most from Aspen fuel, consider these tips:
Store Aspen fuel in a clean, sealed container away from direct sunlight.
Use Aspen fuel in machinery that will be stored for months to avoid stale fuel issues.
Always check manufacturer recommendations, but know that Aspen is often approved for use in most 4-stroke & 2-stroke engines.
When transitioning from pump petrol, it's important to clean the fuel system to eliminate any deposits and replace the main fuel line before using Aspen. For small 2-stroke engines, it is recommended to replace the carburettor diaphragms and fuel hoses prior to switching to Aspen.
Summary
Aspen fuel offers clear advantages for petrol-powered machinery. Its purity and lack of ethanol protect engines from corrosion and deposits, leading to longer engine life and better performance. The long shelf life of Aspen fuel reduces maintenance and storage worries. Businesses and individuals who rely on petrol machinery can benefit from cleaner running, longer run times, and fewer fuel-related problems by choosing Aspen fuel.
