Lawn Mower Oil: What to Use

Lawn mowers are excellent household and professional equipment required for clearing your lawn and keeping it neat and well-manicured all season. But gas lawn mowers need proper maintenance to keep working well, and will also help extend its life span. When it comes to the maintenance of your lawn mower, one of the essential things you must pay attention to is the type of oil that is compatible with your mower engine. It is also crucial to make sure that the type of oil you decide to use is ideal and best for your specific lawn mower. Not all lawn mower engines accept any kind of oil, some are designed to be selective and can only work with a specific kind of oil. Since the oil is responsible for driving the engine, it is critical that you pay special care to this factor as the wrong type of oil will lead to the breakdown of the engine, and this is something you definitely want to avoid.

Lawn mower oil, what to use:

For smaller lawnmowers use high-quality mall engine detergent oil classified as “SF, SG, SH, SJ” or higher. Do not use any special additives, but rather use synthetic oils as these are acceptable at all temperatures. Check the lawn-mowers owners manual what they recommend. For big lawn mowers with a big engine, motor oil that is also used for your car can be used, but also in this case check the owner’s manual.

However, before you change the oil in your lawnmower, there are some factors that should be taken into consideration. First, you need to fully understand the oil types that are well suited for the climatic conditions of your region. It is also important that you consider the oil capacity of your lawnmower as well as the type of lawnmower that you’ll be using. The three determining factors of the type of oil to use are the type of lawnmower equipment you’re working with, the engine type, and the temperature of your work area.

These factors also determine how much you need and the cost of the oil. Once you can pay attention to important details like these, you will be able to bring the best out of your engine. Do you want to know what lawn mower oil to use for your machine? Are you curious about the types of oil that are available? You’re in the right place. In this article, we will talk about lawn mower oil, the different types available, and the right one to use for your lawn mower.

Types of Lawn Mower Oil

There are two main types of oil for lawn mowers, and these include: motor oil and small engine oil. There are some major differences between these two types of lawn mower oil, and they shouldn’t be used interchangeably. Small engine oil is specifically designed for two-stroke engines and is well suited for environments with high temperatures as it protects the engine from overheating. Motor oil, on the other hand, is used for equipment with large motors such as tractors. That being said, let’s take a look at these oil types separately.

Motor Oil

Motor oil is specially designed for equipment with larger motors which include, automobiles, riding lawn mowers, and deluxe push mowers. This type of oil can be easily purchased at gas stations, hardware stores, as well as auto parts stores. There are some homeowners that believe that the regular engine oil can be used for lawn mowers, however, this could cause great damage to the engine of the lawn mower.

Motor oil has a high viscosity, which is why they are specifically designed for automobiles and tractors with large motors. If used for simple machines like your push mower, they may clog up the tool, causing irreversible damage to the engine. Undoubtedly, a lawn mower is a great investment, but you wouldn’t want to ruin this handy tool by doing some wrong routine maintenance. This is why you must pay attention to the type of oil you purchase for your type of lawn mower.

Small Engine Oil

Unlike the motor oil, small engine oil is made for two-stroke engines, which are common in outdoor power equipment such as push mowers, chainsaws, weed trimmers, and snow blowers. The reason for this is because a two-cycle engine does not have separate compartments for oil and gasoline. This is why the result is a louder and smokier machine that does not stop under different types of engine load. This also means that the users have to mix the fuel and oil first, before adding it to the tank. Usually, the gas and oil are mixed at a ratio of 32:1 or 50:1, depending on the type of machine. To make sure you’re working with the right ratio, check the owner’s manual for more information.

Additionally, small engine oil, which is usually referred to as two-stroke oil, is non-viscous and light in weight to aid the even-mixing of the gas and oil, as well as to ensure smooth engine operation. Small engine oil can be found at any auto parts store or in the garden section of a hardware store.

What Type of Oil to Use in Your Lawnmower

The right type of oil that should be used for your lawn mower depends on a number of factors, which include the type of lawn mower you use, the engine in the mower, and the outdoor temperature of the area where you will be mowing.

Type of Lawn mower:

Lawnmower manufacturers typically recommend a specific type of oil for the lawn mower. You can take out time to read the owner’s manual of your lawn mower to know the right type of oil the manufacturer recommends for your specific lawn mower. You can also find most of this information online on the manufacturer’s website.

Mower’s Engine:

It is very important that you know the type of engine in your lawn mower. This will help you determine the type of oil that you should use. You should never use a motor oil in a two-cycle engine. Two-cycle engines require specialized lightweight oil or small engine oil, such as oils with APR performance ratings of SF, SH, SG, or SJ. On the other hand, standard motor oil is best suited for four-cycle engines, because the engine has separate compartments for storing the gasoline and oil. Also, the specific type of motor oil that you should use in a four-cycle engine depends on the outdoor temperature of your area.

Outdoor Temperature:

If you’re working in a place with warmer temperatures, SAE 30 is the most suitable option for your engine. However, in colder areas, it is wise to stick with the SAE 5W-30 motor oil. If the temperature of your work area varies between 0° and 100°, then you should go for an SAE 10W-30 motor oil instead.

You should always keep in mind that motor engines require regular oil changes, as this will help lubricate the engine parts, to ensure the proper functioning of the machine and avoid unnecessary damage. That is why it is important to know the type of oil that is suitable for your machine.

Below are the categories of lawn mower oil to help with your decision making:

SAE 30:

SAE 30 is a detergent type of oil used for warmer temperatures and smaller motors. It is best suited for temperatures of 40 degrees Fahrenheit and above. Since it is lightweight, push lawn mowers can use it to lubricate the engine parts without clogging.

SAE 5W–30:

Suitable for temperatures below 40 degrees Fahrenheit, this oil type is particularly recommended for the winter season as it protects the engine longer at any temperature within this range.

SAE 10W–30:

This oil type is suitable for temperature conditions that vary between 0 degrees to 100 degrees Fahrenheit. While it may increase the consumption rate, it will also improve starting your engine in cold weather conditions.

Synthetic 5W–30:

This oil type is suitable for temperatures between 20 degrees to 120 degrees Fahrenheit, to provide adequate protection against any temperature with chances of reducing oil consumption.

Vanguard 15W–50:

This is often used for varying temperature range, as well as for prolonged use, such as in commercial lawn mowing or pressure washing.

How to Check the Oil in Your Lawnmower

While it is essential to use the right type of oil for your lawn mower engine, it is also important to check the oil level in your mower regularly. This process is pretty similar to how you would check the oil level in your vehicle. All you simply need to do is, remove the dipstick from the lawnmower and wipe it off using a clean piece of cloth. Then insert the dipstick fully back into place. To get better results, twist the dipstick back into place before pulling it back out to check the oil level. The oil residue on the dipstick should be somewhere between the full and add marks. Once the residue is lower than the add mark, then you should add more oil in your mower. If not, then your mower should be able to run for additional hours.

Final remarks

In conclusion, when choosing your lawn mower oil, be sure to use a high-quality detergent oil classified as “SF, SG, SH, SJ” or higher. Do not use any special additives, but rather use synthetic oils as these are acceptable at all temperatures.

What Type of Oil Goes in a Lawn Mower?

A number of factors determine the type of oil you should use in your lawn mower.

The most important thing is to select the right viscosity (the state of thickness of the fluid). The correct viscosity will help your small engine to be thoroughly lubricated, even during times of temperature change.

Viscosity

Two basic viscosities are used for lawn mower engines – SAE 30 is your choice for mowing during times of warm weather, and 10W-30 is your choice for cold weather.

SAE (Society of Automotive Engineers) 30 is a single grade oil that is traditionally chosen to use in smaller air-cooled engines like those used in lawnmowers, tractors, and chainsaws. SAE 10W-30 oil is a single grade oil that can be used at lower temperatures (the W stands for Winter).

Two Stroke Oil

If your mower has a two-stroke engine (an internal combustion engine that completes one power cycle with two up-and-down movements of a piston during one crankshaft revolution), you’ll need to use a combination of gasoline with two-stroke oil.

What type of engine your lawnmower has should be listed in the manual and in all manufacturer instructions.

• You can’t use regular automotive oil for a lawn mower that has a two-stroke engine – the detergents and additives in automotive oil aren’t healthy.

Choose two-stroke oil that is labeled SF, SG, SH, and SJ (these are all performance ratings assigned by the API (American Petroleum Institute).

Generic Or Name Brand?

All the top lawn mower brands will push their brand of oil, but you don’t have to buy one specific brand. You can use a generic oil that has been specially formulated to use in lawn mowers and will benefit from lower for the same quality of oil.

What About Oil Additives?

There are a plethora of oil additive bottles on the shelves of automotive stores, but don’t give in to the temptation to add them to lawnmower fuel. Lawnmowers have small engines, and additives are only useful for large engines.

But, you should consider using a gas additive if the gas you are putting into your small engine has ethanol. [1]

Can You Use A Synthetic Lawnmower Oil?

The short answer is yes, you can.

In fact, synthetic SAE 5W-30 works best in both extremely cold temperatures (down to.20º F) and extremely hot temperatures (up to 120º F). SAE 5W-30 will provide better starting and will consume less oil in the long run.

Don’t Want To Deal With Oil?

If you don’t want to deal with oil, think about buying either an electric or cordless mower. They don’t need their oil changed – ever…which is a real selling point to some people and better for the environment.

What’s the Best Type of Oil for a Craftsman Lawnmower

Engine oil keeps your engine all lubed up, preventing friction damage, and helps keep your engine’s heat down. To keep your lawn mower running smoothly for a long lifespan, it’s crucial to stay on top of regular maintenance like oil changes. Since there are many types of oil for lawn mower engines, we consulted experts to find the best oil for your lawnmower.

What kind of oil should you use for a craftsman lawnmower?

SAE 10W-30 lawn mower oil is the most adaptable and may be used in any situation; it is adequate for most climates. In contrast, SAE 5W-30 could be preferable in colder climates. You might also use synthetic oil, which will thicken from pollutants rather than deteriorate or get thinner over time. Synthetic oils are great for all climates and can help provide your craftsman mower with better lubrication durability.

Check the Owner’s Manual

When you buy a new lawnmower, it should come with a manual. If not, you can find your manual online. Keep this manual handy to find the manufacturer’s safety tips and operating instructions.

You should always consult your owner’s manual to confirm the manufacturer’s specific oil recommendations.

You can lookup craftsman mower owners manuals here.

Environmental Factors Impacting Craftsman Lawn Mower Oil Recommendations

A decrease in lubricant layer thickness due to low viscosity during the summer is one of the critical concerns for equipment operating in hot climates. The capacity of an oil to flow and form an oil film thick enough to separate lubricated engine parts is determined by its viscosity, which is critical. Inherently, in hot climates, higher viscosity oil is recommended.

Synthetic vs. Conventional Oil for Craftsman Mowers

You must pay attention to the weight you use, synthetic or conventional oil. Different weights are applied to both synthetic and conventional oils, such as a multiweight (10W-30 is a frequent example) or a straight weight (“straight 30” is frequently quoted).

Multiweight oils consider several temperature ranges; for instance, 10W-30 performs as a 30-weight oil while the engine works at operating temperature and as a 10-weight oil when the temperature is indicated as cold. While Straight 30 will use similarly to 30-weight when the engine is running, it makes no promises regarding cold starting and operation.

How Much Oil Does a Craftsman Lawn Mower Take?

You must pay attention to the weight you use, synthetic or conventional oil. Different weights are applied to both synthetic and conventional oils, such as a multiweight (10W-30 is a frequent example) or a straight weight (“straight 30” is frequently quoted). Multiweight oils consider several temperature ranges; for instance, 10W-30 performs as a 30-weight oil while the engine works at operating temperature and as a 10-weight oil when the temperature is indicated as cold. While Straight 30 will use similarly to 30-weight when the engine is running, it makes no promises regarding cold starting and operation.

How Often Should You Change the Oil in Craftsman Lawn Mowers?

It is recommended to change and replace the oil in existing push mowers, as seen in the video below, at least once every season or after 50 hours of use. It is advised to change and replace the oil in existing riding mowers at least once every season or after 100 operating hours.

Maintaining your lawn mower properly will ensure it functions well for many years. One area of lawn mower maintenance that is sometimes forgotten is how frequently oil changes should be performed. At least once every spring or summer, or after 50 hours of use, whichever comes first, engine oil and oil filters should be changed.

Most mower engines require an oil change after 20 to 50 operating hours. The owner’s handbook specifies how frequently to change the oil in a mower. An oil change and other seasonal tune-up maintenance should be performed at the very least annually.

Can You Put Car Oil in Your Lawnmower?

Your lawn mower needs clean, premium oil for efficient operation and extended service life. You may use motor oil in a lawn mower as long as it’s high-quality and the right oil for your particular mower.

In general, SAE30 is a decent option for both cars and lawnmowers. Always check with the manufacturer or dealer if you’re unsure which oil is appropriate for your equipment. Make sure to use oils that conform to your manufacturer’s recommendations and your lawn mower will thank you with many more years of use.

Can I use 10w30 instead of SAE 30 in my lawn mower?

Yes, 10w30 and SAE 30 are both appropriate for lawnmowers. The SAE 30 will provide excellent protection if your mower is older and has more wear. That said, the heavier oil may cause problems for some small engines.

The standard motor oil grade for many lawnmowers is 10W30. The precise quality needed will be specified in your owner’s manual. However, 10W30 is typically the best option for four-stroke engines. Any oil intended for vehicles or trucks will function admirably in your lawn mower.

Wondering What Motor Oil to Use in My Lawn Mower?

Much like your car engine, your lawn mower engine requires important tune ups and maintenance. This will keep your mower running well and save you a lot of the headaches that come from delayed maintenance. One key maintenance requirement for any combustion engine is regular oil changes, but it’s important to know what motor oil to use in your lawn mower.

The Short Answer

Most modern lawn mowers have a 4-stroke engine (if your mower has an oil dipstick, then it’s 4-stroke), and for this type of mower most SAE-30 motor oils will work well. 2-stroke mowers require a special mixture of gas and oil to function properly. Either way, I recommend that you consult your mower’s owner manual to determine the best type of oil for your mower’s engine.

Using the wrong kind of oil can result in engine damage, so keep reading if you’d like to learn more.

When to Change Your Mower’s Oil

If you use your mower year round, then aim to change the oil every 20 to 50 hours of use.

Lawn Mower Oil Basics

There are different types of motor oil for lawn mowers and other small engines. Even the climate you live in can affect the type of oil that you should use.

It’s important to understand what the differences are. This will help you to choose a motor oil that is safe for your lawn mower.

The last thing you want to do is use the wrong oil and ruin your engine.

Different Strokes for Different Folks

The first distinction that is important when deciding what oil to use in your mower is whether it is a 2-stroke or 4-stroke engine.

There are key differences between these two types of engines that factor into what oil to use.

The most important thing to know is that a 4-stroke engine has separate compartments for gas and oil while a 2-stroke does not. This means that a 2-stroke engine requires a premixed ratio of gas and oil within the same compartment.

In general, a 2-stroke engine is a small motor, while a 4-stroke engine is more complicated – more like the motor in your car.

These days most modern lawn mowers are 4 stroke engines, but if you’re not sure what type of mower you have just look for an oil dipstick. If your mower has one, it’s a 4-stroke engine.

Different Types of Motor Oil

Many people believe that all motor oils are the same and can be used interchangeably with any type of motor, but that is simply not the case.

Many small motors cannot take automotive oil due to it being a thicker consistency. It can end up clogging different parts of the machinery, which is just the opposite of what motor oil is intended for.

Conversely, small motor oil will be too thin to properly lubricate a larger engine.

Motor Oil to Use in Lawn Mowers with 4-Stroke Motors

Motor oil found in an auto parts store or gas station can usually be safely used with a 4-stroke engine.

These engines are common on tractors, riding mowers, and larger push mowers. However, some engines don’t do well with certain oil additives, so it is still good to check the owner’s manual to be sure.

A pretty safe bet could be SAE-30 oil if you’re in a pinch. This type of motor oil is readily available and used a lot.

The best way to check the oil level in your mower is by pulling the dipstick from the oil compartment. Do this when the machine has not recently been running. Wipe it, re-insert it, and check then check the level when you pull it out again.

This will give you the most accurate measurement and let you know if you have added enough oil.

An average push mower with a 4-stroke engine may need up to 18oz of oil. A large riding mower engine can require up to 64oz.

You never want to over-fill your lawn mower with oil or your mower may start to smoke. I always recommend topping up your oil slowly and checking with the dipstick until you get the level just right.

Motor Oil to Use in Lawn Mowers with 2-Stroke Motors

Smaller mowers and other small machines likely have 2-stroke engines, which need a specific ratio of gas and oil within the same chamber. The ratio can range from 20:1 to 50:1 depending on the motor. This information can be found in your owner’s manual.

Oil for small engines is lightweight and should have APR performance ratings of SF, SH, SG, or SJ to indicate that they are compatible for 2-stroke motors.

It is also possible to find premixed formulations of gas and oil based on your machine’s needs as outlined in the owner’s manual.

Small motor oil is found in the garden department of hardware stores or auto parts stores, separate from automotive motor oil.

Temperature

Interestingly, motor oils work best in certain climates depending on the temperature, which is particularly important for 4-stroke motors.

For example, SAE-30 oil works best between 40 and 100 degrees Fahrenheit.

If you need to operate an engine in colder conditions, then a synthetic oil or other formulation such as SAE 5W 30 may be necessary for optimal operation of your engine.

Companies like Briggs and Stratton endorse synthetic oil. They love its quality, as well as its wider range of acceptable temperatures.

In my opinion you can go with old-fashioned motor oil or synthetic, but I recommend staying consistent in what you use.

Check the Manual

Before you decide what motor oil to use in your lawn mower, check your lawn mower owner’s manual.

The manual will tell you exactly what kind of oil is ideal for your specific machine.

And even if you got your mower used (without a manual) or misplaced your mower’s owner’s manual you can quickly find it online with a search for your mower’s make and model number.
