Mix your own, or buy it ready-made?
You have two routes. Mix your own with a quality 2-stroke oil (like Motul Garden 2T) and fresh petrol — cheapest, but you must measure accurately and use it reasonably fresh. Or buy ready-mixed alkylate fuel (like Aspen 2) — more expensive, but benzene-free, healthier to breathe, and stable for years so it never goes stale between seasons.
Get the ratio right
Most modern machines run 1:50 (check your manual). Measure carefully — too little oil risks seizing the engine, too much fouls the plug. Whatever you use, fresh fuel is the single biggest factor in easy starting. See our buying guide.
Frequently asked questions
What oil should I use in a 2-stroke brush cutter?
A quality 2-stroke oil designed for air-cooled garden engines, mixed at the ratio in your manual (commonly 1:50). A universal semi-synthetic like Motul Garden 2T works across all brands.
What is alkylate fuel and is it worth it?
Alkylate fuel (like Aspen 2) is pre-mixed, benzene-free and stores for years. It's cleaner for your health and your engine, and removes the need to mix — ideal for occasional users, at a higher price.
What is the correct 2-stroke mixing ratio?
Most modern machines use 1:50 (some older ones 1:40). Always follow your manual, measure accurately, and use fresh fuel — stale mix is a common cause of starting problems.
Can I leave fuel in my brush cutter over winter?
Ordinary petrol mix goes stale and gums up carburettors. Either drain it, or use alkylate fuel like Aspen which stores for years without degrading.

Which one for which need
Getting through a season
The volume determines how many mixes you get before buying again. With regular use, the large container works out markedly cheaper.
Avoiding old mix
Mixed fuel ages and fouls the engine. A small container used up quickly avoids keeping mix that degrades.
Who each type suits
- Regular use
- Mixing it yourself works out markedly cheaper per litre. The rigour of the dosage then becomes the only constraint.
- Occasional use
- Ready-mixed fuel keeps for years and removes the risk of a dosing error. It is where it most justifies itself.
- Winter storage
- It is fuel aged in the tank and the carburettor that causes most refusals to start in spring.
The trade-offs to weigh
- Home mix against ready-mixed
- Home mix costs far less per litre and assumes an exact dosage; ready-mixed fuel keeps for years and costs several times more.
- Volume bought against shelf life
- A large can of mix works out cheaper and degrades over time. Mix is prepared according to what you will actually use.
- Synthetic oil against mineral
- Synthetic fouls less and lubricates better when hot, for a modest premium. It is where the saving shows itself fastest in use.
Questions buyers ask
What happens if the mix is too low in oil?
The engine lacks lubrication, overheats and can seize. That is a permanent failure, and it is the most expensive mistake in this range.
And if the mix is too rich?
The engine smokes, fouls the spark plug and loses power. That is reversible, unlike a mix that is too lean.
Can car fuel be used?
Only mixed with two-stroke oil in the right ratio. Putting neat petrol into a two-stroke engine destroys it within minutes.
How do I prepare a mix correctly?
In a dedicated, graduated can, oil then petrol, shaking before every fill. Pouring straight into the tank mixes nothing.
How do I recognise aged fuel?
It takes on a varnish smell and a darker colour. An engine that refuses to start in spring almost always points to that fuel.
What should I do before winter?
Drain the tank then run the engine until it stops, to empty the carburettor. That is what prevents the spring breakdown.
Does alkylate fuel change anything?
It keeps for years without degrading and gives off markedly fewer irritant compounds. Its cost reserves it for occasional use or for sensitive users.
Where should fuel be stored?
In an approved can, cool, away from sunlight and any heat source, outside the home.
What to remember
A mix too low in oil seizes the engine, and that is permanent: mix in a dedicated, graduated can, never in the tank. Drain and run the engine until it stops before winter — aged fuel explains most refusals to start in spring.
