How to Mix Weed Eater Gas

How to Mix Weed Eater Gas

What do you think will happen if you run your car with the wrong fuel? Well, your car’s engine is likely to get damaged, which may cost you more money for repairs than you would have anticipated.

Similarly, a weed eater requires the right type of fuel as well as the right gas mixture for it to operate efficiently. Most weed eaters today are operated by a two-cycle engine, which requires a correct mixture of gasoline and oil to keep the piston and the crankshaft well lubricated.

Gas and oil should always be mixed in the correct ratios because too much oil can hurt the engine while too little oil can cause insufficient lubrication, which later ruins your engine’s moving parts.

Weed Eater Brands

Before deciding on the mix ratio you’re going to adhere to, you need to understand that weed eaters are available in different brands and models. Each mix ratio depends on the model of the weed eater you own.

Among the common mix ratios you’ll get with most trimmers include 40:1 that converts to 3.2 ounces of oil to one gallon of gas, 32:1 that converts to four ounces of oil per a gallon of gas and 50:1 that’s equal to 2.6 ounces per a gallon of gas.

How To Mix Fuel

Step 1

Before you even touch anything, the first step to consider is reading the available user manual. The reason for this is to allow you understand the mixing criteria to avoid making any errors. Secondly, a manual allows you to understand the exact type of engine your trimmer is using so that you can know how to mix the ratio between gas and oil.

Step 2

Next, you have to check whether or not you’re using the right container for your machine. Most weed eaters come with specific containers that have been approved by the manufacturer. A good example of a perfect gasoline container is the no-spill fuel container that’s designed to reduce spillage and evaporation.

Step 3

Next, consider choosing premium gasoline over regular gas for your weed trimmer. Choosing a cheap gas may prove fatal and might damage your engine in the long run. According to most weed eater manufacturers, using mid-grade unleaded gasoline is the best option.

The best octane rating for the best gasoline is 89. If your fuel has a lower octane rating, it will have a higher chance of overheating your trimmer’s engine, which may damage the machine.

Step 4

Once you’ve sorted out the fuel type, make sure that you use the STIHL premium quality two-cycle oils to protect your engine at the highest level. Different trimmers come with different engine capacities. If your model uses the 40:1 ratio of gas to oil, make sure that you mix 3.2 ounces of oil to one gallon of regular gasoline.

On the other hand, models that rely on the 50:1 ratio of gas to oil means that one should mix 2.6 ounces of oil to one gallon of gas.

Step 5

Now that you’ve understood how to mix oil and gas in their correct ratios, let’s do this practically. Take a clean canister as recommended by the manufacturer. Start by pouring oil before adding gasoline. After you’re done, close the fuel canister tightly then mix the fuels vigorously.

Step 6

It’s now time to pour the fuel mixture into your trimmer’s gas cylinder. To do this, first clean the fuel cap to prevent dirt from penetrating through when pouring the fuel.

Pour the fuel with the machine’s cap facing upward to prevent any possible inhalation of fuel vapor. Always make sure that you shake the fuel canister before refueling your trimmer to avoid any possible reheating or damaging of the engine.

Fuel warnings

Just to mention, weed eaters should not use gasoline with an alcohol concentration of more than 10 percent. Too much alcohol in the gasoline can ruin some engine parts as well as cause the engine to overheat.

Also, using gasoline that hasn’t been mixed with oil can cause serious damages to the engine such as lack of lubrication that can make the moving parts such as the pistons to wear out quickly.
