After spending a day we are choosing the right oil for your lawn boy’s lawn mower engine.

Briggs and Stratton Engine Oil

Briggs and Stratton Is the Most Reliable Engine for Lawn Mowers. but The Drawback Is, that It Required Different Types of Oil Based on The Weather.

  • SAE 30 oil best for – 4-cycle engine and temperature 40°-100° f temperatures
  • SAE 10 w-30 oil is best for – the winter season
  • SAE 5 w-30 motor oil is best for – 40° to +120° f temperature

Kohler Engine Oil

Every type of engine, but it’s also important to use the correct weight oil for the temperature range in your region. For engines that will be operated in temperatures that are close to average, SAE 10W-30 is a good choice. However, if the temperatures fall below 0 degrees Celsius, you should quickly turn to a heavier weight oil, like SAE 30 or 40. Using the incorrect weight oil can cause damage to your engine and may even lead to complete failure.

Honda Engine Oil

Honda engines are some of the most popular options on the market. They come in a variety of types, including GX120, GX200, and GX160 engines. These 4-stroke engines ideally need SAE 10W-30 engine oil to run properly and protect against wear and tear.

How Much Oil Does a Lawn-Boy Mower Hold?

Oil requirement varies for different brands and models. It primarily depends on the size of the engine. For example, a lawnmower with a small engine will only require 1 quart of oil, while a tractor may need up to 10 quarts. 

If you need to replace the oil in a lawn-boy mower, it will hold 20 fluid ounces of oil. Be sure to check your owner’s manual for the specific requirements of your model. Many factors can affect how much oil your machine needs, including climate and driving habits. 

Always use the type of oil specified in your owner’s manual. You can usually find this information on the product label or on the company website. Using an incorrect type of oil can damage your engine and void your warranty.


In conclusion, it is important to know what type of oil is safe to use in your lawn boy lawn mower. They are using three types of engines. So we recommend you based on the engine types and temperature choose the best one.
