The best 2-stroke oil & fuel
The right oil and fuel keep a petrol brush cutter starting easily and running for years. Here's what we'd put in the tank — from universal 2-stroke oil to ready-mixed alkylate fuel.
A universal semi-synthetic 2-stroke oil that works across all brands — the dependable, good-value choice for mixing your own fuel.

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.
