Can You Use Car Oil in a Lawn Mower?
Many homeowners often ask whether they can use car oil for lawn mowers. This makes perfect sense because part of maintaining this machine is using the right oil. Pouring the wrong type into its engine can impact its performance and lifespan.
Experts' answer is this oil type is not for lawn mowers because:
- Excessive Wear and Tear: Car oils may not give enough lubrication for lawn mower engines. Car oils are thicker than the ideal for lawn mower engines. The more viscid the oil, the harder it is to circulate inside the engine, causing it to overwork.
- Engine Damage: Many car oil brands contain additives not suited for lawn mowers. These substances may cause deposits or sludge buildup in small engines. This can lead to engine damage.
- Reduced Machine Efficiency: The engines of these backyard maintenance machines are air-cooled. They also run at higher RPMs than car engines. Using the wrong type of oil can affect the performance of your lawn mower, making it less efficient and more prone to breakdowns.
Types of Lawn Mower Engines
For your lawn mower to run without a hitch, choosing the right type of oil for your mower’s engine type is crucial. Lawn mowers engines fall under two types:
- 2-stroke engines need a mixture of oil and gasoline. The oil lubricates the engine parts. As such, it's critical to use the correct oil type to prevent engine damage.
- 4-stroke engines require oil similar to car engines, but you still need to check if the specific formulations do not damage your mower.
Types of Oil You Can Use for Your Lawn Mower
The next question is, what oil types work best for your lawn mower. There are three main types for lawn mowers. The best type to use depends on the right engine type, climate of the lawn and how you use your mower.
- Conventional Oil (SAE 30): As the most common type of lawn mower oil, it is best suited for warmer climates (temperatures above 40°F). It's a good budget-friendly option but has many limitations. For heavy machine use, this type does not offer the same level of protection as synthetic oils.
- Synthetic Blend Oil (SAE 10W-30): This contains a mixture of conventional oil and synthetic oil. It offers a good balance between performance and price. It's a good choice if you live in an area where there are moderate temperature variations.
-
Full Synthetic Oil (SAE 5W-30): This provides the best performance and protection from extreme temperatures. It is also recommended for heavy use, The only downside is its price.
