How much oil does a riding lawnmower take? What pros say

A well-oiled machine is the secret to a perfectly manicured lawn. Your riding lawnmower is no exception. With our comprehensive knowledge, we can provide the exact details you need. Let’s explore this together for the best lawn care experience.

How much oil does a riding lawnmower take?

The oil capacity of riding lawnmowers varies by brand and engine size, typically ranging from 16-64 oz. Check your manual for the specific capacity and oil type recommended. Adding a few extra ounces or using thicker oil may help in older mowers or hot climates.

Do you know the key to a well-manicured lawn could be as simple as the right oil in your riding lawnmower? But how much oil is just right? And what type should you use? Keep reading to learn more!


How much oil does my riding lawnmower need:

The amount of motor oil that a riding lawnmower needs depends not only on its tank capacity but also on its working environment. Remember that when the mower is cold, the amount may seem different. It’s essential to learn about the right oil for your lawnmower.

● Components that need motor oil

The primary purpose of oil in lawnmowers is to maintain the engine. It lubricates the engine parts and flushes the waste away from the burning fuel. The engine’s oil movement makes the oil pick up dirt, debris, and junk formed due to combustion and frictional effects. It keeps the engine tidy and clean.

But as time passes, the oil becomes too crude to work efficiently, and you must change it. The use of synthetic oil can extend the life of your engine. The engine’s oil flows through several small parts. It runs to reduce friction and lower the temperature inside.

It is primarily used in the cylinders for lubrication, keeping them safe from any damage caused by excess friction or heating.

It also keeps the cylinder’s rings working ideally. Generally, the oil also has an oil filter in its flowing pathway, purifying it each cycle. Other parts, like the camshafts and crankshafts, must be lubricated; the oil will also reach those parts.

Using synthetic oil in commercial lawnmowers and oil for small engines can provide additional benefits. However, the use of synthetic oil does not replace regular maintenance.

● Oil requirements for different brands

The amount of oil depends on the lawnmower type and its engine size. Here are some lawnmower brands and the amount of engine oil they need:

  • Honda: The Honda lawnmower engine needs 18 Oz of oil. 
  • Briggs and Stratton: Briggs and Stratton Lawnmower’s oil tank holds 48 – 64 oz.
  • Toro: Toro lawnmower’s oil capacity is around 16 Oz.
  • John Deere: John Deere lawnmower holds 48 Oz of motor oil.
  • Craftsman: The Craftsman lawn mower engine’s oil capacity is around 20 Oz.
  • Husqvarna: Depending on the model, the Husqvarna lawnmower’s oil capacity is around 48 Oz.

● Oil requirement with mower’s age and environment

If you’re regularly using the lawnmower, you should periodically check and change the oil according to the manufacturer’s maintenance specifications. The life of conventional engine oil is about fifty hours. In some giant riding lawnmowers, it may have a longer life, up to 100 hours.

This oil life depends on the additives used in your mower oil, the oil’s storage state, and the temperature conditions. The optimum temperature to stock the lawnmower oil is between 40 °F and 85 °F. 

In my 20 years in the field, I’ve seen signs that a lawnmower might need an oil change, including dark, dirty oil, excessive smoke, and decreased engine performance. Regular oil checks can prevent damage and ensure optimal performance

If your annual usage is around 50-60 hours, expect to change the oil yearly. Different kinds of oil can work best at certain temperature conditions.

– Understanding Oil Types for Different Weather Conditions

Oil types and usage depend on the weather in your area, too. Those living in hotter countries will generally have to use motor oil that is thicker in grade and add a few extra ounces to adjust to this. Those living in a colder area will have to use a lighter oil and slightly less.

This is because the oil’s viscosity changes with temperature. The smaller amount is enough to cold-start the engine.

The amount of oil a riding lawnmower needs also depends on age. You will have to use an oil with greater viscosity for older mowers. Such oil also gets used up more quickly, so experts recommend adding a few additional amounts (4-8 Oz) to an old mower’s tank.

This extra amount will help balance the riding mower’s oil burn. The older a lawnmower gets, the more critical it is to regularly check the oil level to be sure it does not run low.

● The difference between the various oil types:

  1. SAE 30: It is used in warmer temperatures and is the most commonly used oil for small mower engines. So, it should be used in lesser amounts and is unsuitable for larger mowers.
  2. SAE 10W-30: It is used for varying temperature ranges. This type of oil improves cold-weather starting but may enhance oil consumption. This oil is the best for riding mowers. For a larger riding lawn mower, 48 Oz is sufficient.
  3. Synthetic SAE 5W-30: It starts with low oil consumption and is typically used for all but the very extreme temperature ranges. Nowadays, lawnmower synthetic oils are highly suggested because of their wide temperature range. This oil is such that it will still do the job even if you use a few ounces less.
  4. SAE 5W-30: They are recommended in cold weather conditions. This is the same as the SAE 10W-30 oil. For a larger riding lawn mower, 48 Oz is sufficient.

Additional concerns:

Some common concerns regarding the adequate oil amount that a riding lawnmower requires are:

  1. Do not overfill: You must never use motor oil at a greater capacity than the recommended level. Extra oil makes the oil tank. This gets stuck in the cylinders, filter, and seals. It may especially cause severe harm to the engine seals if you use a more significant amount regularly a few times.
  2. Do not underfill: You must never use less oil than what is recommended in the mower’s manual. A lesser amount means that each part will get relatively less lubrication. It also can cause raised temperatures. If you regularly use less motor oil, your lawnmower engine will ultimately seize.
  3. Add only similar oil: Use the same kind of oil each time. If the mower consumes too much oil, consult a specialist and shift towards a thicker oil. Never use 2 different types of oil in a mix.

Frequently asked questions:

1. What should I do if my mower consumes too much oil?

Usually, a lawnmower can use its oil, which should last 50 hours or more before it needs to be changed. When your lawnmower ages, the engine starts consuming it faster, and the oil level can drop quickly. If your lawnmower is consuming more oil than it should, you need to check these parts:

  1. Crankcase: Check your crankcase for any cracks or extra oil.
  2. Piston rings: Damaged piston rings are another common cause, so fix them.
  3. Low capacity: A low oil level in your engine can cause the engine to run too hot, and the remaining oil will wear much quicker. Additionally, the dirt in the oil is now concentrated in a smaller amount, increasing the engine’s wear and tear.
  4. Low viscosity: The oil viscosity grade is one of the causes of increased oil burning.
  5. Damaged engine parts: The oil may be overused as some parts may be damaged.
  6. Leaks: If there is a problem with one of the engine gaskets, leaking can occur. It means that the gasket needs to be replaced. Or if the engine overheated, it is also possible that the metal was damaged and the engine parts did not fit as well as they should.
  7. Use a thicker oil: Shift towards a thicker oil with guidance from an expert. This is where the right oil for your lawnmower comes into play. The use of synthetic oil can provide better support for your engine.

2. How often should I change my engine oil?

How often you change engine oil depends on the type of lawnmower (engine size) you use. There are three major types used, as mentioned below:

  1. Push Mowers: Changing your oil after 25 hours of usage is recommended.
  2. Walk-Behind Lawnmower: Its oil capacity is around 15 to 18 Oz (0.47 to 0.56 quarts). You have to replace the motor oil every 50 hours or yearly.
  3. Riding Lawnmower: It holds 48 to 64 Oz (1.5 quarts to 2 quarts) and changes oil every 100 hours or annually.

3. What type of oil is best for my mower?

The type of oil depends on the environmental temperature of the location you are living. For outdoor machines in warmer locations, SAE 30 is your best option. In colder areas, you should stick with SAE 5W-30 motor oil.

If you are in a place where the temperature fluctuates between 0° and 100°, you should use an SAE 10W-30 motor oil.

Remember, synthetic oil provides better protection for your engine, but it’s important to note that it does not last forever. So, it’s crucial to choose the right oil for your lawnmower.


Changing your mower oil is an important maintenance step to keep your mower working for years to come. It is suggested that the engine oil is checked regularly. Knowing the correct oil level is equally important. Riding lawnmowers are heavy machines that can stress the engine from time to time.

Oil maintenance is essential. A wrong oil level may cause unwanted engine problems and expensive repairs. In this article, the oil capacity for various brands of lawnmowers has been explained. But always check the user manual for the correct amount of oil and the recommended oil type. Happy mowing.

Checking Oil Levels in Your Riding Lawnmower

Checking your riding lawnmower’s oil level is an essential maintenance task. Regular checks prevent the engine from running low on oil, which can cause significant damage. Regarding oil consumption, it’s crucial to note that engines use more oil as they age.

• Understanding Oil Viscosity

An essential aspect of proper oil usage is understanding viscosity. Oil variance in thickness, commonly called viscosity, directly impacts consumption. Thicker oils are consumed less than thinner oils in lawnmower engines.

In my two decades of experience, I’ve found that the typical oil capacity for a riding lawn mower is between 48 to 64 ounces, although it can vary depending on the model. It’s crucial to check your owner’s manual for the exact specifications.

• Matching Oil to Your Lawnmower Model

Various factors determine the type and amount of oil your lawnmower needs. These include the lawnmower’s brand, model, age, and location. Different oil capacities for other lawnmower brands have been established based on these factors.

For instance, Honda requires 18 Oz, Briggs, and Stratton requires 48 to 64 Oz, Toro needs 16 Oz, John Deere uses 48 Oz, Craftsman needs 20 Oz, and Husqvarna consumes 48 Oz.

•Check Your Oil: Regular Checks and Changes of Oil

Maintaining optimal performance and avoiding costly repairs is made possible through regular oil checks and changes. It’s essential to use the correct type and amount of oil to prevent engine seal damage and seizing.

Using the Briggs & Stratton Oil Finder tool, you can find the ideal oil for your lawnmower, engine type, and weather conditions. This tool is convenient for ensuring maintenance procedures follow Briggs & Stratton warranty compliance.

• Synthetic vs. Standard Oils

Synthetic oils are often recommended over standard oils. Their temperature range is vast, and they provide superior protection at all temperatures. Correspondingly, synthetic oils are acceptable across all temperature ranges and do not affect the required oil change intervals.

• Avoiding Overfilling and Underfilling

Balancing oil levels is a fine art: overfilling can cause engine seal damage, while too little oil can lead to overheating and, ultimately, engine failure. Remain consistent with your oil type and avoid mixing different oils.

• Diagnosing an Overconsuming Lawnmower

An unusually high oil consumption could indicate various issues, such as cracked crankcases, damaged piston rings, low oil levels, low viscosity, damaged engine parts, leaks, or overheating.

• Following Recommended Oil Change Intervals

Keep track of oil change intervals. For push mowers, change the oil every 25 hours. Walk-behind mowers require an oil change every 50 hours or annually, while riding mowers necessitate an oil change every 100 hours or annually.

• Selecting an Oil Suited to Your Climate

Geographical location directly impacts which oil is best for your lawnmower. Warmer regions may require SAE 30 oil, while colder regions might be better suited to SAE 5W-30 oil. Areas with fluctuating temperatures may need the versatility of SAE 10W-30 oil.

• Selecting High-Quality Detergent Oil

Detergent oils classified as For Service SF, SG, SH, SJ, or higher are ideal for lawnmower engines. Additives should be avoided as they can compromise engine performance.

• Checking and Changing Oil Correctly

Ensure your mower is on a level surface when checking and changing oil. Step-by-step guidance can be found on accredited educational resources like PennState’s College of Agricultural Sciences or your manufacturer’s guide.

In conclusion, maintaining your lawnmower involves regular oil checks and changes, choosing the right viscosity, understanding your machine’s oil capacity, and selecting an oil suitable for your location’s temperature range.
