How to Check and Add Oil to Your Lawn Mower

To ensure your lawn mower’s optimal performance, you must check and add oil regularly.

To do this, locate the oil dipstick on the mower and remove it. Check the oil level and color, add oil if necessary, and make sure you use the right type of oil recommended by the manufacturer.

Checking the Oil Level

First, you should check the oil level of your lawn mower before starting it up, as it’s crucial for proper engine function. Neglecting to check the oil level can lead to serious engine damage and costly repairs.

Regular maintenance is important for your lawn mower’s longevity, and checking the oil level is one of the most critical steps. To check the oil level, locate the oil cap and remove it. Then, wipe the dipstick clean and reinsert it into the oil cap.

Remove the dipstick and check the oil level against the markings on the dipstick. If the oil level is low, add oil until the level reaches the full mark. Remember to avoid common mistakes such as overfilling the oil or using the wrong type of oil, which can also cause engine damage.

Adding Oil

Adding oil is a vital step in maintaining your lawn mower’s engine health, ensuring it runs smoothly and efficiently. Without oil, the engine’s moving parts would generate excessive heat, leading to friction and wear.

This could ultimately cause serious damage to the engine, and even render it unusable. Therefore, it is essential that you keep your lawn mower’s oil level at the correct level, and change it regularly to keep the engine in good condition.

When adding oil, it is important to consider the viscosity of the oil you choose. Viscosity refers to how easily the oil flows, and is measured using a scale from 0 to 60. A higher number indicates a thicker, more viscous oil, while a lower number indicates a thinner, less viscous oil.

Different engines require different viscosities of oil, so you should always check your lawn mower’s manual or speak to a professional to determine the appropriate viscosity for your engine. Additionally, you should consider the frequency at which you change your oil. Most manufacturers recommend changing your oil every 50-100 hours of use, or at least once a year.

Choosing the Right Type of Oil

Choosing the Right Type of Oil

Now that you know how to add oil to your lawn mower, it’s important to choose the right type of oil to ensure your machine runs smoothly.

There are two main factors to consider when choosing oil: viscosity and whether to use synthetic or conventional oil.

Viscosity refers to how thick the oil is and its ability to flow. A higher viscosity oil will be thicker and flow more slowly, while a lower viscosity oil will be thinner and flow more easily.

The owner’s manual for your lawn mower will provide a recommended viscosity range for the oil to use. Additionally, you’ll need to consider the temperature range you’ll be operating your lawn mower in to ensure the oil doesn’t become too thick or thin.

The synthetic oil is usually more expensive than conventional oil, but it performs better in extreme temperatures, lasts longer, and reduces engine wear.

Conventional oil is cheaper and readily available, but may not perform as well in extremely hot or cold temperatures and may require more frequent oil changes.
