Why Use Aspen 4 Instead of Ordinary Petrol?
One of the biggest differences between Aspen 4 and conventional forecourt petrol is ethanol.
Aspen 4 contains no ethanol.
Standard E10 petrol sold in Ireland can contain up to 10% ethanol. Ethanol attracts moisture and can create problems in small petrol engines, particularly when machinery is left unused for extended periods.
This makes Aspen 4 especially useful for:
- Lawnmowers
- Generators
- Garden machinery
- Construction equipment
- Water pumps
- Marine engines
- Seasonal equipment
- Backup machinery
Ordinary Petrol – Use It Fresh
Modern E10 petrol is not well suited to extended storage in small engines.
It is recommended that conventional petrol is kept fresh and that fuel which has been stored for extended periods is not used in small machinery.
A useful rule for machinery owners is:
Aim to use conventional petrol within approximately 30 days.
This is especially important for machinery that may sit unused between jobs or during winter.
Aspen 4 – Stable for Years
Aspen 4 is specifically designed for excellent storage stability.
Aspen states that its alkylate petrol can remain stable for approximately 3–5 years.
That gives a simple comparison:
Conventional petrol – aim to use within approximately 30 days.
Aspen 4 – storage stability of approximately 3–5 years.
For machines that are not used every week, this can be one of the strongest reasons to choose Aspen 4.
Aspen 4 for Lawnmowers
Aspen 4 is an excellent fuel choice for compatible 4-stroke petrol lawnmowers.
Lawnmowers are typically used heavily during spring and summer but may then sit unused for several months over winter.
Ordinary petrol left in a mower for extended periods can deteriorate.
Aspen 4 is:
- Ethanol-free
- Long-life
- Ready to use
- Designed for compatible 4-stroke engines
- Particularly suitable for seasonal machinery
Is Aspen 4 Good for Winter Lawnmower Storage?
Yes.
Because Aspen 4 remains stable for years, it is particularly useful for lawnmowers and other machines that may remain unused throughout winter.
Always follow the storage instructions provided by the machinery manufacturer.
Aspen 4 for Petrol Generators
Aspen 4 is particularly useful for petrol generators.
Generators are often purchased for emergency or backup use and may sit unused for months before being needed.
When an emergency happens, you want the generator to start.
Using a long-life, ethanol-free petrol reduces the concerns associated with storing ordinary E10 fuel for extended periods.
Aspen 4 can be suitable for:
- Home backup generators
- Emergency generators
- Construction site generators
- Workshop generators
- Event generators
- Standby power equipment
Why Use Aspen 4 in a Backup Generator?
A backup generator might only be required a handful of times per year.
Ordinary petrol stored for months can deteriorate.
Aspen 4 can remain stable for approximately 3–5 years, making it particularly useful for equipment that must remain ready for use.
Aspen 4 for Construction Equipment
Aspen 4 can also be used in compatible 4-stroke petrol construction machinery.
Typical examples may include:
- Petrol plate compactors
- Vibrating plates
- Water pumps
- Generators
- Power floats
- Small construction machinery
- Other equipment powered by compatible 4-stroke engines
Always check the manufacturer’s fuel specification before use.
At A-Z Hire, we sell, hire, service and repair petrol-powered machinery, so if you’re unsure which fuel your equipment requires, ask us.
How Do I Know if My Machine Is 4-Stroke?
A typical 4-stroke machine has separate engine oil.
You will normally find an:
- Engine oil filler
- Dipstick
- Oil level plug
- Separate oil sump
The petrol is added to the fuel tank without mixing in 2-stroke oil.
Does Aspen 4 Contain 2-Stroke Oil?
No.
Aspen 4 does not contain added 2-stroke oil.
This is one of the easiest ways to remember the difference:
Aspen 2 = petrol with 2-stroke oil already included.
Aspen 4 = petrol without added 2-stroke oil.
Aspen 4 vs Aspen 2 – What’s the Difference?
Choosing between Aspen 2 and Aspen 4 depends on the type of engine in your machine.
Aspen 4
Aspen 4 is primarily for compatible 4-stroke petrol engines.
It offers:
- No added 2-stroke oil
- No ethanol
- Long storage life
- Ready-to-use alkylate petrol
Typical applications include:
- Lawnmowers
- Generators
- Cultivators
- Water pumps
- 4-stroke outboards
- Construction machinery
Aspen 2
Aspen 2 is designed for compatible land-based 2-stroke engines.
It already contains fully synthetic 2-stroke oil premixed at 50:1.
Typical Aspen 2 applications include:
- Chainsaws
- Consaws
- Power cutters
- Hedge trimmers
- Brushcutters
- Clearing saws
- Pole pruners
Separate engine oil usually means Aspen 4.
Oil mixed into the petrol usually means Aspen 2.
If you’re unsure, ask A-Z Hire before filling the machine.
Is Aspen 4 Ethanol-Free?
Yes.
Aspen 4 contains no ethanol.
Ireland’s standard E10 petrol can contain up to 10% ethanol.
Ethanol can absorb moisture, making ethanol-containing petrol less suitable for machinery that sits unused for long periods.
Aspen 4’s ethanol-free formulation is one of its main advantages for seasonal and standby machinery.
Cleaner Fuel for Your Engine
Aspen 4 is an alkylate petrol rather than conventional forecourt petrol.
It contains significantly lower levels of substances such as benzene, aromatic hydrocarbons and olefins.
Potential benefits include:
- Cleaner combustion
- Reduced deposits
- Cleaner spark plugs
- Cleaner combustion chambers
- Reduced strong petrol smell
- Excellent storage stability
- No ethanol
This makes Aspen 4 particularly attractive for both professional and domestic machinery users.
Can I Switch From Ordinary Petrol to Aspen 4?
In compatible machinery, Aspen 4 can generally be used instead of conventional petrol.
If you are switching from ordinary petrol, you do not normally have to completely empty every trace of fresh petrol from the system.
However, if the petrol already in the machine is old or stale, it is better to remove it rather than mixing new Aspen 4 with deteriorated fuel.
Always follow the engine manufacturer’s fuel recommendations.
Aspen 4 for Marine Outboards
Aspen 4 can also be suitable for marine applications.
Can I Use Aspen 4 in a 4-Stroke Outboard?
Aspen 4 can be used in compatible 4-stroke petrol outboards where the engine manufacturer permits alkylate petrol.
Because Aspen 4 contains no ethanol, it can be particularly attractive for boats that may spend periods unused.
What About a 2-Stroke Outboard?
Two-stroke marine outboards require particular attention to the manufacturer’s specified oil and fuel ratio.
For many two-stroke marine applications, Aspen 4 can be mixed with the correct marine 2-stroke oil at the ratio specified by the outboard manufacturer.
Do not automatically assume Aspen 2 is suitable for a marine outboard.
Check the engine manufacturer’s requirements before use.
Is Aspen 4 Good for Machinery That Is Rarely Used?
Yes. This is one of the strongest reasons to consider Aspen 4.
Examples include:
- Emergency generators
- Lawnmowers
- Rotavators
- Water pumps
- Backup construction equipment
- Boat engines
- Seasonal garden machinery
These machines may remain unused for weeks or months.
Aspen 4’s 3–5 year storage stability makes it particularly useful where reliable starting after long periods of storage is important.
Aspen 4 vs Ordinary E10 Petrol
Ordinary E10 Petrol
- Can contain up to 10% ethanol
- Best used fresh
- Aim to use within approximately 30 days
- Ethanol can attract moisture
- Can deteriorate during storage
- Less suitable for seasonal machinery
Aspen 4
- Ethanol-free
- No added 2-stroke oil
- Ready to use
- Designed for compatible 4-stroke engines
- Approximately 3–5 year storage stability
- Cleaner alkylate petrol formulation
- Ideal for seasonal and standby machinery
