The information here should provide you everything you need to know to keep your machinery running without ever encountering any problems with fuel.


1) Ensure fuel is fresh
2) Buy fuel with 10% ethanol or less (ideally 0%)
3) If buying pump fuel use a fuel stabilizer (Briggs & Stratton fuel fit or similar)
4) Stop dirt from entering the fuel tank, make sure the fuel cap, surrounding area and funnel are clean. Use a funnel with a filter screen
5) Store fuel in an approved container which is clean, in a cool, dry place away from direct sunlight.

Problems with fuel

Stale fuel – fuel starts to deteriorate after 30 days of storage

Ethanol – causes corrosion to fuel components and attracts water

Dirty fuel – blocks up fuel filters and carburetors

Incorrectly stored fuel – fuel can evaporate away, fuel vapours are dangerous and incorrectly stored fuel can become contaminated.

A brief comparison of fuel

Aspen – no ethanol, will stay fresh for up to 5 years, 99% less toxic emissions, prolongs machinery life, a ready mixed 2 stroke version is available

Regular unleaded – can contain ethanol, will stay fresh for 30 days

Super unleaded – can contain ethanol, will stay fresh for 30 days

Regular unleaded with fuel stabiliser – protects against the effects of ethanol, keeps fuel fresh for up to 3 years.

Aspen Fuel

We only use Aspen fuel in our workshop and this is why;

1) We know the fuel we are putting in your machine will be fine when you come to use it.
2) Aspen 2 is ready mixed and will work in any 2 stroke machine regardless of what mixture of 2 stroke it requires
3) It is better for the health of the person working with the machine as it produces 99% less toxic emissions.

Ideally always use Aspen, if this is not cost effective we recommend using Briggs & Stratton Fuel Fit as a high quality fuel stabiliser in regular unleaded.

Storing equipment for a long period of time

When storing equipment for a long period of time (i.e. lawnmowers over winter) run equipment out of fuel, then use Aspen fuel, run for a few minutes and shut the engine down. It is advisable to store the fuel tank at the maximum recommended level. If this is not possible make sure it is stored empty of fuel.

Briggs & Stratton Fuel Fit

Fuel Fit is the latest fuel treatment by Briggs & Stratton.
Briggs & Stratton’s new and improved Fuel Fit keeps fuel fresh and protects engines more than ever before.
Fuel Fit not only keeps the carburettor clean for easy starting but now also protects against the corrosive effects of ethanol and maintains fuel stability for up to 3 years.

Fuel FAQ’s

Which fuel should you use?
Fuel with less than 10% ethanol, ideally 0% ethanol.

How do I know how much ethanol is in fuel?
The pump will be labelled E5 which tells you it has up to 5% ethanol E10 will be 10% ethanol. Fuels with more than 10% ethanol will invalidate your warranty with most small engine manufactures. You can test fuel for ethanol, we sell a kit to test for ethanol or we can test fuel for you.

Can I use fuel containing 2 stroke oil in my 4 stroke machine?
No, this will damage your machine.

Does cheap 2 stroke really make a difference?
Yes, always use a high quality 2 stroke oil. 2 stroke oil is the lubricant for the engine and the better the 2 stroke is the longer the machinery will last. Cheap 2 Stroke oil is of poor quality.
