The right mix of fuel and additives in your weed eater tank will ensure your trimmer operates at maximum capacity.
Just like your vehicle will malfunction if the incorrect fuel is used, your weed eater will suffer the same fate.
The right type of fuel will power your weed eater and protect its components from corrosion. It will also help it run longer and stronger and increase durability.
Mind the Manual
Before you even think about mixing fuels, first check your manual. Your manual should help you select the best combination of fuel and mixture to use.
Checks and Balances
Next, check to ensure you are using the correct container best suited to your type of machine. Always use the approved container as directed.
Cheaper is not always Better
The cheaper brands os fuel may not always be the best option for your trimmer. Some premium brands may be a bit pricey, but prove better for your weed eater in the long run.
Mix and Match
Most gas trimmers are driven by small 2-cycle engines that are lubricated through the fuel system.
- The lubricating system needs a mixture of oil and gas to ensure the engine’s moving parts are continually lubricated. It is important, then, to get the right balance between oil and gas.
- The right mixture should start with unleaded, mid-grade fuel. The minimum mixture of octane to gasoline should be at least 89. Lower octane ranges may cause the engine temperature to escalate.
If the engine temperature rises, chances are, the piston may overheat and damage the engine.
A good blend should be at least a ratio of between 40:1 or 50:1.
The combination should be at least 3.2 ounces of 2-cycle air cooled engine oil to 1 gallon of 87 octane regular grade unleaded gas.
One gallon of fuel will need at least 2.6 fluid ounces of oil. If you use 2.5 gallons of fuel, at least 6.4 fluid ounces of oil can suffice.
Another option to consider is STIHL premium quality 2-cycle oils. 2-cycle oils are known to help protect your engine at all levels.
Stir it up
Take your time and mix the liquids correctly. If the oil is not enough, it may reduce the engine’s power and overheat, resulting in damage to the internal components.
Conversely, too much oil can lead to exhaust carbon buildup and excess smoke and fumes.
- Start with a clean, empty tank. Clean away any dirt, dust or debris. Pour the oil in first and add 1 gallon of gas. Leave enough room in the container to hold both mixtures
- Screw the cap firmly in place and swish vigorously to thoroughly mix.
- Always shake the can when you are refueling.
- Do not mix oil and gas together in the weed eater’s fuel tank. It’s likely you’ll get the combinations wrong, and they won’t mix well.
- Don’t use gas with at least 10 percent alcohol present in it. Excess alcohol in the fuel can corrode the gas lines and other parts. It can also cause the engine to overheat.
- Don’t use straight, unmixed fuel in your weed eater tank. If you use gas without lubricating oil, it can quickly damage the engine.
