Mixing chainsaw fuel involves combining a specific type of oil with petrol at the correct ratio in an approved container.
To mix chainsaw fuel, you need to combine two main components: two-stroke oil and petrol. The most common ratio for modern chainsaws is 1:50. This means for every 50 parts of petrol, you add 1 part of oil. Always refer to your chainsaw's manual for the exact ratio required, as it can sometimes vary.
Here is a simple process based on the provided reference:
- Gather Materials: Ensure you have the correct two-stroke oil for chainsaws, fresh petrol (unleaded is typical), and an approved fuel canister.
- Determine Amounts: Calculate the quantities of oil and petrol needed based on the 1:50 ratio and the amount of fuel mix you want to create.
- Combine in Canister: Pour both substances (the oil and petrol) into an approved fuel canister.
- Mix Thoroughly: Shake the canister to mix the oil and petrol together evenly. Proper mixing ensures the oil is distributed throughout the fuel, providing necessary lubrication for the engine.
- Fill the Chainsaw: Open the canister carefully to release any pressure buildup and fill your chainsaw up with the fuel mix.
Understanding the Ratio (1:50)
The ratio is crucial for your chainsaw's health. A 1:50 ratio means the oil makes up 1/51st of the total mixture.
Here's what that looks like for common volumes:
Petrol Volume | Oil Volume (1:50 Ratio) | Total Fuel Mix |
---|---|---|
1 litre | 20 ml | 1.02 litres |
5 litres | 100 ml | 5.1 litres |
1 US Gallon | 2.56 fl oz | ~1.01 US Gallon |
Note: Always use measuring tools designed for fuel and oil to ensure accuracy.
Mixing at the correct ratio is vital. Too little oil can lead to engine damage due to lack of lubrication, while too much oil can cause excessive smoke, poor performance, and carbon buildup.
Remember to only mix the amount of fuel you expect to use relatively soon, as mixed fuel can degrade over time. Always store mixed fuel in a cool, dry place away from ignition sources, using a properly labeled and approved container.
