The operating temperature of a lawn mower can be different around the year. And the climate has an unavoidable impact on the machine. Moreover, oil viscosity is another important factor when choosing an oil type.

Therefore, when you choose a particular Kawasaki FR730V oil type, make sure you consider some factors that we will discuss below.

Kawasaki FR730V Oil Type: Lawn Mower Oil Recommendations

Kawasaki FR730v engine oil type can be many. The oil type that you may use will depend on the operating conditions of your engine, as well as your personal preferences. Check this table below for various oil types to use in different temperatures and choose according to your regional climate-

Oil Type/GradeOperating TemperatureBest Temp To Use
SAE 3040-100°F/4-38°CWarm Temp
SAE 10W300-100°F/-18-38°CWarm to cold temp
SAE 5W30-20-40°F/-29-4°CCold temp
SAE 10W40-13-104°F/-25-40°CBest for all temp
Vanguard Synthetic 15W5020-120°F/-7-49°CVarious temp

You cannot use just any oil in your Kawasaki lawn mower. Some of the most common oil for Kawasaki FR730V engines include synthetic oil and blends. Besides, it is recommended to use 4-stroke oil or any equivalent oil with SJ or a higher class certified.

Automotive oils lack various additives that prevent engine damage, like- high-lubricity zinc. Therefore, you need to pick an oil type that not only would serve the purpose of fueling the engine but also save the engine from damage.

According to Kawasaki Engine USA, you can use synthetic blends- 10W-30, 10W-40, or 20W-50 for the ultimate low and high-temperature applications. They added that the oil blend 10W-40 is greatly preferred for most weather conditions. However, they recommended changing oil viscosity according to regional/seasonal temperature changes.

The following oil type matches the requirement for a Kawasaki mower engine in various weather situations. Have a look!

SAE 30: This engine oil is most suitable for warm climates where the temperature ranges between 40° to 100°F. It is preferable for smaller engines.

SAE 5W-30: The SAE 5W-30 engine oil is mostly preferable for very cold temperatures. The best operating temperature for this oil is between -20°F to 40°F. The 5W-30 oil has zinc as an additive for performing better in a colder temperature preventing wear and tear on engine parts.

Synthetic 5W-30: Whether it is a warm or cold climate region, you can use this engine oil in extreme weather conditions. It provides the best performance between -20°F to 100°F. This synthetic blend also has zinc to reduce damage to engine parts. To get an improved starting and reduced oil consumption, give this one a go.

SAE 10W-30: SAE 10W-30, also known as 10W-30, is a common oil type for lawn mowers in a wide range of temperatures. The temperature range covers colder weather, having a range from 0°-100°F. It improves the engine starting in a cold climate. However, you may need to refill more frequently. Therefore, keep an eye on the engine oil level.

Vanguard 15W-50: The Vanguard 15W-50 lawn mower engine oil is mostly preferable for commercial use where the engine has to work continuously without a break. The operation temperature for this oil is between 20°F to 120°F. You can use it as pressure washer fuel as well.


  • Operating temperatures above 27°C or 80°F will lead to more oil consumption for the SAE 10W30 oil type. So, you should keep an eye on the engine oil level. You may need to refill more frequently.
  • Follow the Kawasaki FR730V oil recommendation in the user manual for the appropriate oil level for a particular engine.
  • Don’t overfill the mower engine with oil when refilling. Use the oil finder tool to prevent wasting.
  • A temperature below 4°C or 40°F for SAE 30 will lead to a hard engine start.

When Does The Kawasaki FR730V Engine Need Oil Change?

The Kawasaki FR730V Engine has a fixed oil changing schedule written in its manual. The manual says that the first oil change of this lawn mower engine needs to be done after the very first 8 hours. After that, you need to change the oil every year.

No matter what type of oil you choose, it is important to make sure that you change your oil regularly. Kawasaki recommends that you change your oil every 50 hours of operation or once per year, whichever comes first.

We recommend changing the oil in the fall to prevent picking up corrosive particles from the environment. If you are to store it for the next season, store it with clean oil and vacate the contaminated fuel from the engine compartment.

Frequently Asked Questions (FAQs)

How much oil does a Kawasaki FR730V Take?

A Kawasaki FR730V lawn mower engine takes approximately 2.1 quarts or 2.0 liters of oil.

What Kind Of Oil Does A Kawasaki Lawn Mower Engine Take?

Kawasaki lawn mower engines can take different viscosity motor oil depending on the temperature you are using it. The basic oil type is SAE 30 oil. However, SAE 10W-30 and 10W-40 engine oil are also common in this lawn mower engine. You may need to change the oil viscosity according to the seasonal temperature. Also, change the oil to 20W-50 in a higher temperature region to reduce oil consumption.

What Is SAE 30 Oil?

SAE 30 oil is a motor oil having an Engine Oil Viscosity Grade (developed by Society of Automotive Engineers/SAE) 30. It is commonly used in older vehicles. It is also used in
some lawn mowers and other small engines. This oil is thicker than most other motor oils, which helps to protect older engines from wear and tear.

Is 10w30 The Same As SAE 30?

No, SAE 10w30 is not the same as SAE 30. The main difference between the SAE 30 and 10w30 oil types is their viscosity. SAE 30 is a single-viscosity or single-grade oil that we only recommend for use in engines that operate in warm climates. On the other hand, 10w30 is a multi-viscosity or multigrade oil that is designed for use in engines that operate in a variety of climates. Multigrade oils are designed to flow better at low temperatures than single-grade oils, making them ideal for use in cold weather.

Final Thoughts

The FR730V is a 4-cycle engine that requires a special oil type. Kawasaki FR730V oil type can vary in different ranges and consistency. These oil types can be found at most auto parts stores.

The appropriate oil will help keep the engine running smoothly and prevent any premature wear and tear. Therefore, choose the right oil for the Kawasaki FR730V lawn mower according to the climate in your area and the requirements for the machine.
