Why You Should Check Your Engine Oil Levels

The only way to monitor your engine oil levels is to regularly check your dipstick.

Your dipstick will have two markings on it, one that indicates a high level of oil and one that indicates a low oil level.

You want to keep your oil level between these two markers and closer to the high marker. Both low engine oil levels and oil levels that are too high can cause problems for your engine.

Effects of Low Oil Levels

Oil is crucial for lubricating engine components, reducing friction, and dissipating heat. Without sufficient oil, these components can overheat and wear out rapidly, potentially leading to engine damage or failure.

Low oil levels can also cause the oil pump to lose its ability to circulate oil effectively, resulting in inadequate lubrication and increased friction, which can lead to engine failure.

Effects of High Oil Levels

While most people are aware that low engine oil levels can cause problems, having too much oil in the engine can also cause issues. Excessive oil can create increased pressure within the engine, leading to leaks or seal damage.

The crankshaft may come into contact with the oil, causing it to aerate or foam. This foamy oil loses its ability to lubricate effectively, as the air bubbles will reduce the oil's ability to maintain a stable film between moving parts.

In extreme cases, too much oil can result in oil being drawn into the combustion chamber, leading to fouled spark plugs, increased emissions, and potential damage to the catalytic converter.
