Do Lawn Mowers Take Regular Gas

Maintaining your lawn and garden is a tiresome but necessary task. To maintain the beauty and health of your lawn, you should use the right garden and lawn equipment. One of the most important pieces of equipment is a lawn mower. Before purchasing a lawn mower, you should know what type of gas it takes. Do lawn mowers take regular gas?

In this blog post, we’ll discuss the type of gas that lawn mowers require, why the type of gas matters, and the benefits of using the right type of fuel in your lawn mower.

Types of Gasoline for Lawn Mowers

Lawn mowers are usually powered by either gasoline or electricity. Gasoline lawn mowers operate on a two- or four-stroke engine. Smaller, residential lawn mowers are usually powered by a two-stroke gasoline engine while larger, commercial lawn mowers use four-stroke gasoline engines. Lawn mowers powered by two-stroke engines require two different types of fuel: two-stroke oil and gasoline.

Two-stroke oil is specifically designed for use in two-stroke engines and features synthetic additives that help reduce smoke, unburned fuel, and exhaust emissions. This type of oil is not suitable for use in four-stroke engines as it does not provide adequate lubrication.

Gasoline for lawn mowers is usually regular grade 87 octane unleaded gasoline. You should not use higher-octane fuels, as this could lead to engine knocking or pre-ignition which can cause damage to your engine. You should also not use E-10 gasoline, as it contains up to 10% ethanol which can damage the rubber seals, gaskets and fuel lines of the engine.

Why the Type of Gas Matters

Different types of gasoline contain different additives, detergents, and octanes. Using the wrong type of fuel can have a significant impact on the performance and life of your lawn mower engine. Gasoline that is low in detergents can result in the accumulation of deposits in the engine, decreasing power and fuel efficiency. Conversely, using the wrong type of fuel can also lead to premature wear and tear of the engine.

Using the correct type of gasoline in your lawn mower is critical for ensuring the performance and longevity of the engine. Using a gasoline with the correct octane rating is essential for preventing the engine from experiencing pre-ignition or engine knocking. Using the wrong octane rating can also lead to fuel consumption and engine damage.

Benefits of Using the Proper Fuel

Using the correct gasoline for your lawn mower can offer a number of benefits for your engine and your lawn mowing experience.


When you use the correct fuel for your lawn mower, you can ensure that your engine will last longer and stay in tip-top shape. Simply put, the right fuel paired with proper maintenance will ensure that you get the most out of your lawn mower.

Increased Performance

Using the right type of gasoline can also result in improved engine performance. This can translate to a faster, smoother, and more consistent mowing experience.

Better Fuel Efficiency

Proper gasoline not only ensures better engine performance, but it can also increase fuel efficiency. This leads to reduced fuel consumption, resulting in cost savings over the long term.

Bottom Line

Maintaining your lawn can be hard work but with the right equipment, it doesn’t have to be. Before purchasing a lawn mower, it’s important to know what type of gasoline it takes.

For lawn mowers powered by two-stroke engines, you must use two-stroke oil and regular grade 87 octane unleaded gasoline. E-10 gasoline should not be used in any lawn mower. Using the proper fuel can ensure better engine performance and fuel efficiency as well as increased engine longevity.

So, the answer to the question, “Do lawn mowers take regular gas?” Is yes, they do.
