Understanding the Right Fuel Mix Ratio
Ensure the longevity and efficiency of your petrol grass trimmer or brush cutter by using the correct fuel mixture. Learn about the importance of mix ratios and how they impact the performance and lifespan of your tools.
Importance of Correct Fuel Mix Ratio
Using the correct fuel mixture is crucial for maintaining the health of your grass trimmer or brush cutter. Incorrect mix ratios or unsuitable fuels can lead to severe damage, including piston seizure and excessive wear, ultimately shortening the lifespan of your equipment. Remember the essential mix ratio for 2-stroke fuel:
STIHL 2-stroke engine oil:
1 part oil to 50 parts petrol (1:50 ratio)
Proportions Calculation
Achieving the correct fuel mix ratio is essential. For example, to create a 1:50 ratio, mix 5 litres of petrol with 0.1 litres (100 ml) of oil.
Choosing the Right Petrol
Select high-quality petrol with a minimum octane rating of 90 RON for your grass trimmer fuel mixture. Opting for unleaded petrol with ratings of 95/97/98 RON, widely available at UK petrol stations, enhances performance and promotes environmental and user health.
Selecting Engine Oil
For optimal results, use only high-quality engine oil designed for 2-stroke engines that meet TC classification standards. STIHL 2-stroke engine oil is recommended for its compatibility with STIHL tools and its ability to prolong the life of your grass trimmer.
**Caution:** Inferior engine oil products can cause damage to the engine, sealing rings, and fuel tank of your trimmer.
Mixing Instructions
When preparing your fuel mixture, ensure you use a vessel approved for use with fuels. STIHL combination canisters are ideal for this purpose. Follow these steps:
1. Pour the oil into the canister first, followed by the petrol.
2. Seal the canister and shake it thoroughly to combine the fuel mixture.
3. Exercise caution when opening the canister to release any built-up pressure.
