What Kind Of Oil Does A Lawn Mower Take?

Today you’re going to learn all the different kinds of oil a lawn mower takes.

And most important: what kind of oil you need for your lawn mower.

We will also talk about the benefits of using different oils in your lawn mower and how to change the oil yourself.

Here’s the gist of lawn mower oil types:

  1. The best type of oil for your lawn mower will depend on your climate since different oil is best for different temperature ranges.
  2. The common oil type is conventional SAE-30 because it has a common range of temperatures it should be used in:
    • 40 Fahrenheit (4 Celsius) to 100 Fahrenheit (37 Celsius) which covers most the of climates in the US.
  3. If you live in a colder area conventional SAE 10W-30 may be better for you. It has a lower range and will improve starting in cold weather.
    • 0 F (- 17 C) to 100 F (37 C)
  4. If you live in very cold climate then conventional SAE 5W-30 is your option as it is recommended for use under 40 F (4 C). Great for your snow blower.
  5. The most versatile one-and-done oil that works in all temps you see in the US is synthetic 5W-30 going from – 20 F (- 28 C) to 120 F (48 C). But given the specs it is more expensive.
  6. Another synthetic is SAE 15W – 50 pushing the limits of the operating temperature range to 130 F (54 C). Mainly for commercial riding mowers.
  7. Conventional vs synthetic is simple: Conventional works fine but synthetic works better but is more expensive. Your choice.

The Different Types Of Oil A Lawn Mower Can Take & Their Benefits:

Lawn mowers come in a variety of shapes, sizes, and types. And while they may all look different on the outside, they all have one important thing in common: they need oil to run. But not just any engine oil will do. The type of lawn mower engine oil you use depends on the type of engine it has.

Here are the three most common types of oil used in lawn mowers and their benefits:

  • Conventional
  • Synthetic
  • Biodiesel

Conventional Oil

Conventional oil is the oil used for riding mowers. It is made from crude oil that is refined and then mixed with additives to improve its performance.

  • Benefits: Affordable. Widely available.
  • Cons: Only operates inside certain temperatures.

Synthetic Oil

Synthetic oil is also made from crude oil, but it undergoes a more extensive refining process that gives it better performance properties. Synthetic oil also has additives added to it, but these are different from the ones found in conventional oil.

  • Benefits: Has better performance. Lasts longer under tougher conditions.
  • Cons: More money.


Biodiesel is a renewable source of fuel that is made from plants or vegetable oils. It burns cleaner than both conventional and synthetic oils, making it better for the environment.

  • Benefits: Enviro friendly.
  • Cons: Harder to find. Might not work with all mowers.

Conventional Oil vs Synthetic Oil

Conventional oil is the most affordable option on the market. It is also the most widely available, making it a popular choice for many consumers. However, conventional oil is derived from fossil fuels, which are a finite resource. As supplies of fossil fuels dwindle, the price of conventional oil is likely to increase.

Synthetic oil is another option that is becoming increasingly popular. Unlike conventional oil, synthetic oil is derived from synthetic materials such as polymers or hydrocarbons. Synthetic oil typically costs more than conventional oil, but it often lasts longer and performs better in high-temperature conditions. Additionally, synthetic oils are less damaging to the environment than their fossil fuel-based counterparts.

Oil viscosity and color will vary based on oil types and additives included.

Some Tips For Changing The Oil In Your Lawn Mower:

As any savvy homeowner knows, routine maintenance is essential for keeping your lawn mower in top condition.

One of the most important things you can do is regularly change the oil. This simple task helps to lubricate the engine and prevent excessive wear and tear.

Here are 5 tips to help you change the mower engine oil right:

  1. First, consult your owner’s manual to find out what type of oil is best for your lawn mower. You’ll also want to check how much oil your mower holds so that you can purchase the correct amount.
  2. Next, warm up the engine by running the mower for a few minutes. This will help to loosen any built-up grime and make it easier to drain the oil.
  3. Once the engine is warmed up, turn off the mower and remove the oil fill cap. Then, locate the oil drain plug and use a wrench to unscrew it. Be prepared for a small amount of hot oil to come out when you remove the plug.
  4. Allow all of the old oil to drain out completely before screwing the drain plug back in place. Then, use a funnel to change lawn mower oil into the fill hole. Then check the oil level.
  5. Finally, replace the oil fill cap and start up the engine to check for leaks.
