How To Mix Two-Stroke Fuel for a Lawnmower

The lawnmower is always handy to use. It simplifies your yardwork, particularly in maintaining your lawn. However, keeping your lawnmower in A-1 condition might be as daunting as mixing its two-stroke fuel.

Well, don’t fret. Here is some do-it-yourself advice on mixing two-stroke fuel:

1.    Find out if your lawnmower needs two-stroke fuel. Getting the answer isn’t that intricate. Check your lawnmower unit for indications. There should a label somewhere in your gas tank or in your gas lid. Confirmation could also be provided by your Owner’s Manual. When in doubt, it is always safe and judicious to double-check. Improper mixing of fuel may cause significant damage to your machine.

2.    Understand why you need to mix the fuel properly. Of course, it is obvious. A two-stroke lawnmower is powered by a two-stroke fuel. Lawnmower manufacturers have different mixing variables for their machines. Sometimes, they even vary from country to country. The mixing variables are greatly affected by the fuel emission levels and regulations in the covered area. You may also contact your lawnmower supplier or manufacturer if your need clarification and/or confirmation related to its operation.

3.    Know the standard ratios in mixing a two-stroke fuel. Generally, there are two main ratios, namely: 50:1 and 25:1. Appropriate for a high-end two-stroke oil is the 50:1 ratio. Reason? Because of their better quality, they have inherent fuel stabilizers. They also contain smoke-reduction formulas. Meanwhile, the 25:1 ratio fits low-end two-stroke oil. The main ratios could be detailed and summarized as follows:

50:1    100ml of two-stroke oil to 5 liters of unleaded petrol                     
25:1    200ml of two-stroke oil to 5 liters of unleaded petrol

By the way, before refilling your lawnmower’s tank, shake it a bit. Sometimes, oil settles down and separates from the fuel. You may want to make evenly blend them again before loading up.

4.    Don’t estimate loosely. Buy a measuring cup. However, as a rule, you don’t need to worry about the exact measurement. You have an elbow room of about three ounces. Remember, it is better to run a bit rich than a bit lean. Lesser volume may damage your lawnmower’s cylinder due to the limited amount of lubrication for your oil mix. A proper mix would definitely save you money in the long run.

On a final note, here are some basic care tips to complement your two-stroke fuel mixing endeavor. For one, always use your lawnmower at full power. Don’t hesitate. It has been designed to work that way. Period. Ironically, unused fuel and carbon build up could eventually cause more hassles. Then, as much as possible, don’t lend your lawnmower to anybody. Unless you trust the borrower, your lawnmower deserves to be looked after and taken care of. And of course, have your lawnmower serviced regularly. As a preventive arrangement, a two-stroke lawnmower should be checked up at least once a year. A few extra bucks on the periodic service would afford you a longer usage.
