Let’s dive in!

Types of Oil You Can Use in Your Murray Lawn Mower

i. Single Grade Oil

Single-grade oils are designed for specific temperature ranges. For Murray lawn mowers, SAE 30 is among the best engine oil recommendations for warmer weather, while SAE 10W-30 can be suitable for a varying temperature range.

Single-grade oils provide good protection and are cost-effective.

ii. Multi-Grade Oil

Multi-grade oils, like SAE 10W-30 or 10W-40, are versatile options for varying temperatures. 

They offer improved cold-start performance and adapt to temperature fluctuations, making them popular for year-round use in Murray mowers.

iii. Synthetic Blend Oil

Synthetic blends combine conventional and synthetic base oils. They offer enhanced performance and protection compared to single-grade oils. 

These blends, such as SAE 5W-30 synthetic blends, provide better high-temperature stability and wear protection, ideal for high-demand mowing conditions.

iv. Full Synthetic Oil

Full synthetic oils, like SAE 5W-30 full synthetic, are premium options with superior performance characteristics. They excel in extreme temperatures, offer excellent lubrication, and reduce engine wear. 

While they can be more expensive, they provide top-notch protection for your Murray mower’s engine, especially in demanding conditions.

Engine Oil Recommendation for Murray Lawn Mower

SAE 30 Oil

SAE 30 is a conventional single-grade oil suitable for Murray lawn mowers operating in warmer temperatures.

It provides adequate lubrication and protection for the engine but may not perform optimally in extremely cold conditions. It’s an affordable and widely available option for standard mowing needs.

SAE 5W-30 Synthetic Oil

SAE 5W-30 synthetic oil offers versatility and improved cold-start performance. It’s an excellent choice for Murray mowers in various temperatures, from cold mornings to hot afternoons. 

Cold oil with an SAE 5W-30 rating flows smoothly during chilly mornings, reducing engine wear during start-up. 

As temperatures rise throughout the day, this synthetic oil maintains its protective properties, ensuring consistent lubrication even in the heat.

SAE 10W-30 Synthetic Oil

SAE 10W-30 synthetic oil is another versatile choice suitable for varying temperature conditions. 

It offers enhanced cold-start capabilities and maintains its protective qualities in high heat. This oil is a good all-season option for Murray lawn mowers.

SAE 15W-50 Synthetic Oil

SAE 15W-50 synthetic oil is a robust choice for Murray mowers in demanding conditions or extreme temperature variations. 

It offers excellent protection in cold and hot climates, making it suitable for heavy-duty and high-performance mowing. This oil excels under stress and extended use.

Understanding What SAE Stands For

SAE stands for the Society of Automotive Engineers, an organization dedicated to setting industry standards and specifications for various aspects of automotive and engineering technology.

The SAE has developed a standardized system for classifying motor oils, known as the SAE viscosity grade, which indicates the oil’s flow characteristics at different temperatures. 

This system uses a combination of letters and numbers, such as 10W-30, where the “W” stands for “winter,” and the numbers represent the oil’s viscosity at low and high temperatures.

How to Choose the Right Engine Oil


Ensure the oil you choose is compatible with your lawn mower model and engine type. Consult your mower’s manual or manufacturer’s recommendations for the right oil type to avoid potential engine damage or performance issues.


Consider the level of protection the oil provides for your lawn mower’s engine. Look for oils that offer anti-wear, detergent, and dispersant additives to keep critical engine components clean and protected from friction and deposits.

Oil Quality

Opt for high-quality oils from reputable brands. Quality oils are less likely to break down under high temperatures, ensuring consistent lubrication and protection for your mower’s engine.

Operating Conditions

Take into account the typical operating conditions of your lawn mower. If you frequently mow in hot weather or under heavy loads, choose an oil that can withstand these conditions and provide reliable lubrication.

Oil Viscosity and Grade Compatibility

Pay attention to the oil’s viscosity and grade. Viscosity determines the oil’s flow characteristics at different temperatures. The right viscosity ensures proper lubrication in both cold starts and high-temperature operations. 

The grade (e.g., SAE 30, 10W-30) should match your mower’s requirements and your operating climate.


Consider the climate in your area. Cold climates, like those where a Murray mower won’t start, may require oils with a lower winter viscosity rating (e.g., 5W) to ensure smooth starts.

In contrast, hot climates may benefit from oils with higher viscosity (e.g., SAE 30) to maintain proper lubrication under heat stress. Choose an oil that suits your local weather conditions for optimal performance.

Why You Need the Right Oil Type For Murray

Proper Engine Lubrication

Using the right oil type for your Murray lawn mower ensures that critical engine components receive adequate lubrication. This prevents friction and overheating, promoting smoother operation and protecting against premature wear and tear.

Engine Cleanliness and Reduced Deposits

The correct oil type helps maintain a cleaner engine by minimizing sludge formation and deposits. This cleaner environment contributes to improved combustion efficiency and reduced maintenance requirements.

The right oil type is formulated to match your engine’s specific requirements, enhancing its overall performance. It ensures that vital engine parts move freely and maintain proper compression, improving power and efficiency.

Extended Engine Lifespan

Using the recommended oil type for your Murray mower can significantly prolong the life of your engine. Proper lubrication and reduced wear mean fewer repairs and a longer-lasting mower.

Prevents Excessive Wear

The right oil provides a protective barrier between moving parts, reducing friction and preventing excessive wear. This keeps the engine running smoothly and minimizes the need for costly repairs.

Improved Fuel Efficiency

Correct oil type ensures efficient combustion, which leads to better fuel economy. Using the right oil can help you save on fuel costs over the long run while also reducing emissions.

Minimal Maintenance Needs

When you use the appropriate oil type, your Murray lawn tractor requires less frequent maintenance. This means fewer oil changes and a hassle-free ownership experience, allowing you to focus on lawn care instead of constant upkeep.

Murray Lawn Mower Oil Capacity

Murray Riding Mower

Murray riding mowers come in various models and engine sizes, so oil capacities may differ. Typically, a Murray riding mower with a 17.5 HP engine requires around 48 ounces (1.42 liters) of oil.

The oil capacity for a Murray riding mower with a 20 HP engine is approximately 60 ounces (1.77 liters).

Murray Push Mower

Murray push mowers usually have smaller engines, such as 3.5 HP or 4.5 HP. These models typically require about 20-22 ounces (0.59-0.65 liters) of oil. 

The best you can do is to check your owner’s manual for precise oil capacity for your specific push mower.

How to check oil level: Steps to follow

  • Begin by ensuring your mower is turned off and placed on a level surface. Let it cool down if it has been running.
  • The oil dipstick is near the engine and often has a brightly colored handle or ring for easy identification.
  • Carefully pull out the dipstick and wipe it clean with a cloth or paper towel. This step removes any residual oil from previous checks.
  • Reinsert the dipstick back into its tube and then pull it out again. Hold it horizontally to get an accurate reading.
  • The dipstick will have two marks or notches, usually labeled “Full” and “Low.” The oil level should fall between these marks or within the crosshatched area.
  • If the oil level is below the “Low” mark, add oil slowly through the oil fill tube cap. If it’s above the “Full” mark, drain some oil until it falls within the acceptable range.
  • Repeat the dipstick check after adding or draining oil to ensure the level is within the appropriate range.

How to Change Oil in a Murray Lawn Mower
