Is Conventional Or Synthetic Oil Better For Lawn Mowers?

Maintaining a healthy lawn requires more than just regular mowing and watering – it also involves choosing the right oil for your lawn mower. While conventional oil has been around for decades, synthetic oil is becoming increasingly popular as an alternative to conventional oil.

It’s important to understand the differences between conventional and synthetic oil so that you can make an informed decision about which one is best for your mower. Conventional oil is derived from natural sources such as petroleum, while synthetic oil is lab-created from a combination of base oils and additives.

The two types of oil have different properties and characteristics, so choosing the right one for your lawn mower can be tricky. In this article, we’ll discuss the differences between conventional and synthetic oil and which one is better suited for lawn mowers. We’ll also explain how to determine which type of oil is best for your machine. Once you know the facts, you’ll be able to choose the right oil for your lawn mower with confidence!

What Is Conventional Oil?

Conventional oil is a petroleum-based lubricant made from crude oil that has undergone a refining process. It’s typically broken down further into various grades to meet different engine specifications for various types of vehicles, including lawn mowers.

While the chemical makeup of conventional oil does vary slightly, it usually contains additives to help protect against corrosion and wear and tear.

This type of oil is designed to prevent buildup and clogging in an engine, and it also helps reduce friction between moving parts for smooth operation. It can be used in both two-stroke and four-stroke engines, but it does not provide the same level of protection as synthetic oil.

What Is Synthetic Oil?

When it comes to motor oil, synthetic oil is a great choice for lawn mowers. It is made from man-made base stocks that have been specially engineered and refined to provide superior protection against wear and tear. Synthetic oil also provides superior protection against heat, which can cause an engine to break down or become clogged with sludge.

Synthetic oil also has the ability to lubricate an engine at lower temperatures than conventional oil, allowing it to start easier in cold weather. This makes it an ideal choice for lawn mowers that are used in regions with extreme weather conditions. The superior lubrication of synthetic oil also allows engines to run smoother and quieter than those using conventional oil.

Synthetic oils also contain additives that help keep engines clean by preventing deposits from forming on internal components. This helps extend the life of the engine and keeps it running more efficiently over time. In addition, synthetic oils resist breakdown better than conventional oils, meaning they don’t need to be changed as often. This can save you time and money in the long run, making synthetic oil a great investment for your lawn mower’s engine health.

Differences Between Conventional And Synthetic Oil

When it comes to oil for your lawn mower, you have two options: conventional or synthetic. There are several key differences between the two, so understanding them can help you make an informed decision about which type of oil is best for your particular lawn mower.

Conventional oil is made from natural crude oil and contains additives to improve its performance. It’s a less expensive option and is generally used in older engines that don’t require the additional lubrication of synthetic oils. These oils are typically thicker than synthetic oils and need to be changed more frequently.

Synthetic oil is created through a process called hydrocracking, which breaks down molecules in crude oil into smaller pieces that can be mixed with other elements to create a higher-performing lubricant.

Synthetic oils are thinner than conventional oils and provide better protection against wear and tear on engine parts, as well as improved fuel efficiency when compared to conventional oils. However, they do cost more than conventional oils and need to be changed less often.

In terms of viscosity, synthetic oils are usually thinner than conventional oils at lower temperatures but thickens quicker at higher temperatures which gives them better protection against thermal breakdown. Additionally, synthetic motor oil offers better lubrication due to its molecular structure which helps reduce friction in the engine’s moving components thus improving fuel economy even further.

Finally, when it comes to choosing between conventional or synthetic oil for your lawn mower, it really depends on your individual needs and budget. If you have an older engine or don’t mind changing the oil more often then it might be better for you to go with conventional motor oil.

On the other hand if you want maximum performance from your engine then synthetic motor oil might be worth the extra expense as it provides superior protection against wear and tear while also providing improved fuel efficiency over its conventional counterpart.

Which One Is Better For Lawn Mowers?

Synthetic oil is often seen as the better option for lawn mowers, due to its ability to better withstand high temperatures, its resistance to breakdown, and its extended life span. Conventional oil is made from crude oil, while synthetic oil is made from artificially-created compounds that are designed to be more durable and less prone to breaking down.

Synthetic oils can last much longer than conventional oil, up to 4 times as long in some cases. This means that you don’t have to change the oil in your lawn mower as often. Synthetic oils also tend to be more resistant to temperature extremes, meaning they won’t break down at higher temperatures like conventional oils can. This makes them a great choice for lawn mowers that are used in hot climates or work consistently in hot weather.

Also, synthetic oils provide better protection against wear and tear on the engine components of your lawn mower. The molecular makeup of synthetic oils helps reduce friction between the moving parts of an engine, resulting in fewer repairs over time. Additionally, synthetic oils are able to better protect against rust and corrosion caused by moisture build-up inside an engine’s cylinders.

Overall, synthetic oil offers many benefits for lawn mower owners when compared with conventional oil. However, it may be slightly more expensive than conventional oil so it’s important to weigh up all the pros and cons before making a decision about which type of oil is best for your needs.


In conclusion, when it comes to choosing the best oil for your lawn mower, it is important to consider both conventional and synthetic oils. Conventional oils are usually less expensive and are suitable for use in older models of lawn mowers.

Synthetic oils provide superior performance and durability, but they come at a higher cost. Ultimately, the choice between conventional and synthetic oil depends on your personal preference, as well as the type of engine in your lawn mower. With proper maintenance, either option can keep your lawn mower running smoothly for years to come.
