what petrol should i use in my lawn mower


When it comes to maintaining a healthy and lush lawn, using the right petrol for your lawn mower is crucial. Using the wrong type of petrol can not only damage your mower but also affect the overall performance of your lawn. In this comprehensive guide, we will walk you through everything you need to know about choosing the right petrol for your lawn mower.

Understanding the Basics

Before we dive into the specifics, let’s start with the basics. Most lawn mowers are designed to run on unleaded petrol with an octane rating of 87 or higher. It is important to avoid using diesel, E85, or any other fuel types not recommended by the manufacturer.

Consider the Engine Type

Different lawn mowers come with different types of engines, and the type of engine can influence the type of petrol you should use. The two most common types of lawn mower engines are:

1. Two-Stroke Engines: These engines require a mixture of petrol and oil. Typically, a ratio of 50:1 (petrol to oil) is recommended, but it’s essential to check the manufacturer’s instructions for the specific ratio.

2. Four-Stroke Engines: These engines run on petrol alone, similar to a car engine. You should use regular unleaded petrol with an octane rating of 87 or higher for four-stroke engines.

Consider Ethanol Content

Ethanol is a common additive in petrol, and it can have an impact on your lawn mower’s performance. It is recommended to use petrol with a low ethanol content, preferably less than 10%. Higher ethanol content can lead to issues such as engine damage, decreased power, and increased fuel consumption.

Check the Manufacturer’s Recommendations

To ensure you are using the correct petrol for your lawn mower, always refer to the manufacturer’s recommendations. The user manual or the manufacturer’s website will provide specific details about the type of petrol, octane rating, and any other considerations for your particular model.

Benefits of Using the Right Petrol

Using the right petrol for your lawn mower offers several benefits, including:

1. Improved Performance: The right petrol ensures optimal combustion, leading to better engine performance and smoother operation.

2. Increased Lifespan: Using the recommended petrol reduces the risk of engine damage, extending the lifespan of your lawn mower.

3. Fuel Efficiency: The correct petrol helps your lawn mower operate at its highest efficiency, resulting in better fuel consumption.


Choosing the right petrol for your lawn mower is essential for maintaining its performance and longevity. Always follow the manufacturer’s recommendations, consider the engine type, and opt for petrol with a low ethanol content. By taking these simple steps, you can ensure that your lawn mower runs smoothly and keeps your lawn looking its best.
