What Oil To Use In A Lawn Mower?

When it comes to maintaining your lawn mower, one of the crucial aspects to consider is the type of oil you use. Using the correct oil not only ensures optimal performance but also prolongs the life of your equipment. So, what oil should you use in your lawn mower?

SAE 5W-30 for Cold Temperatures

For those living in regions with very cold temperatures of 40°F and below (5°C and below), it is recommended to use SAE 5W-30 oil in your lawn mower. This oil has the right viscosity to ensure smooth operation even in freezing conditions.

Vanguard 15W-50 for Continuous Use

If you are using your lawn mower for commercial purposes such as continuous cutting or pressure washing in temperatures ranging from 20°F to 130°F, Vanguard 15W-50 oil is the ideal choice. This oil is designed to withstand the rigors of continuous use.

Briggs & Stratton Oil Recommendations

Briggs & Stratton, a well-known manufacturer of lawn mower engines, recommends specific oil types for their engines. It is essential to refer to the manufacturer’s guidelines to ensure that you are using the right oil for your Briggs & Stratton lawn mower.

Why Using the Right Oil Matters

Using the correct oil in your lawn mower is crucial for several reasons. The right oil helps reduce friction, wear, and tear on engine components, ensuring smooth operation and longevity of the equipment.

Preventing Engine Damage

Using the wrong type of oil or old, degraded oil can lead to engine damage, decreased performance, and even complete engine failure. Regularly changing the oil and using the recommended type is vital to prevent such issues.

Checking Oil Levels

It is essential to regularly check the oil level in your lawn mower and top it up as needed. Running the engine with insufficient oil can cause overheating and damage, while overfilling can lead to foaming and reduced lubrication.

How to Change the Oil

Changing the oil in your lawn mower is a straightforward task that can be done at home with basic tools. Simply drain the old oil, replace the oil filter if needed, and refill with the recommended oil type and quantity.

Understanding Viscosity Ratings

The viscosity rating of an oil indicates its flow characteristics at different temperatures. Lower viscosity oils are thinner and flow more easily at low temperatures, while higher viscosity oils are thicker and provide better protection at high temperatures.

Consulting the Owner’s Manual

When in doubt about the correct oil to use in your lawn mower, always refer to the owner’s manual provided by the manufacturer. The manual contains specific recommendations and guidelines to help you maintain your equipment properly.
