How to mix two-stroke oil and fuel for a chainsaw: a simple guide
If you want your Husqvarna chainsaw to run smoothly and last longer, using the right fuel mixture is essential.
The fuel mix powers the engine. If the wrong type of fuel or an incorrect oil ratio is used, it can cause serious damage to your chainsaw.
Why using the correct fuel mix matters
Mixing fuel and oil properly helps protect your chainsaw from:
- Excessive wear on engine parts
- Piston seizure (engine failure)
- Shorter life span of your chainsaw
By using the correct mix, you will keep your chainsaw running at its best for years to come.
How to mix fuel and two-stroke oil the right way
- Use a clean fuel container designed specifically for petrol.
- Start by filling the container halfway with fuel.
- Add the full amount of two-stroke oil to the fuel.
- Shake or stir the mixture thoroughly to combine.
- Fill the rest of the container with petrol and shake the mixture again.
- Only mix enough fuel for about one month’s supply to ensure freshness.
- Mix again before refuelling your chainsaw each time.
What is the correct fuel-to-oil ratio?
For Husqvarna chainsaws, the correct fuel-to-oil ratio is 50:1. That means 2% two-stroke oil to fuel.
EXAMPLE:
- 5 litres of fuel = 100 ml of two-stroke oil
For the best performance, we recommending using Husqvarna two-stroke oil, which is specially designed to protect your chainsaw engine.
Check your chainsaw operator’s manual for detailed information about your specific mode.
