Understanding Engine Oil Pressure

Engine oil pressure is essentially the force with which motor oil is pushed through various channels, tubes, and passages by the engine’s oil pump to lubricate critical moving parts. This lubrication process not only reduces friction between these components but also helps in heat control, as the oil absorbs heat generated from engine parts rubbing against each other.

Higher viscosity oil for engine

The oil pressure is measured in pounds per square inch (PSI) and usually varies depending on the car’s engine type, design, and oil viscosity. It’s critical to maintain the manufacturer’s recommended oil pressure levels at various engine speeds to ensure the longevity of engine oils in the motor.

Typically, oil pressure gauges or sensors installed in the vehicle measure oil pressure in real-time. When working correctly, these devices notify the driver if pressure of oil drops to below a safe threshold by triggering a warning light on the dashboard.

Note: Maintaining the oil’s efficiency is critical for preserving the right oil pressure.

  3. Faulty oil pressure sensor or gauge: Inaccurate readings can occur if the oil pressure sensor or gauge is faulty. In this case, the underlying issue is not with the oil pressure itself but with the measuring devices.

  4. Worn or damaged oil pump: The oil pump is responsible for circulating the oil throughout the engine. Over time, wear and tear can lead to reduced pumping efficiency, resulting in low oil pressure.

  5. Blocked or restricted oil passages: If the oil passages in the engine become blocked or restricted due to debris or sludge, the oil flow will be hampered, leading to low oil pressure.

Signs and Symptoms

Identifying low engine oil pressure early can help you address the issue before it leads to severe engine damage. Some of the most common signs include:

  1. Oil pressure warning light: The most obvious sign of low oil pressure is the warning light on your dashboard. If the light comes on, it’s essential to check the oil level and pressure immediately.

  2. Unusual noises: Low oil pressure can cause increased friction between engine components, leading to knocks, ticking, or whining sounds.

  3. Poor engine performance: Low oil pressure may lead to reduced engine power, poor acceleration, and rough idling.

  4. Overheating: Insufficient oil pressure can result in increased friction, leading to higher engine temperatures and even overheating.

If you notice any of these signs, it’s essential to diagnose and address the issue as soon as possible to minimize potential engine damage.

How to Fix Low Engine Oil Pressure (Step by Step)?

Low engine oil pressure has serious implications on your vehicle’s performance and health. It can be caused due to various reasons, including failing oil pump, clogged oil filter, or even low oil level in the engine.

Oil change to avoid oil leak

The following are comprehensive, actionable steps you can take to fix low engine oil pressure:

Step 1: Verify the Engine Oil Level

The initial step you should take when handling low oil pressure is to verify the current oil level. To do this, remove the oil dipstick, wipe it clean, then reinsert it back into the engine, and pull it out once more. Check the position of the oil mark on the dipstick. If it’s below the “Add” or “Low” line, it means you need to put in more engine oil.

If you find the oil level is low, consider using AirTec High-Class Automotive Oil Additive to top up.

Step 2: Replace your Engine’s Oil Filter

Another common cause of low oil pressure is a clogged oil filter. Over time, the filter can accumulate dirt and debris, lowering the oil pressure. You can manage this situation by replacing the oil filter. As a rule of thumb, it’s usually recommended to change the oil filter each time you change your engine oil.

Step 3: Inspect and Replace the Oil Pump, If Needed

In your engine, the oil pump plays a crucial role in using enough oil and sustaining adequate oil pressure. If your oil pump happens to be dysfunctional, it is recommended to replace it, which should effectively solve the issue of low oil pressure. Be aware that this procedure requires specific tools, knowledge and even experience, so it might be wisest to entrust a professional mechanic with this task.

Maintaining the oil pump includes using high-caliber greases. AirTec Grease G200 Multi-Purpose Plus or AirTec Grease KH150 Full Synthetic from our store offers excellent lubrication to enhance the performance of your oil pump.

Please note that if experience low oil pressure frequently, it might be indicative of a more serious, underlying mechanical problem. In such cases, it’s recommended to consult a professional.

Preventing Low Oil Pressure

Maintaining a healthy engine oil pressure is a crucial aspect of vehicle maintenance.

Avoiding worn piston rings and engine bearings

Here are some preventive measures you can take to minimize the risks of experiencing low engine oil pressure:

  • Regular Oil Changes: This is perhaps the most effective way to prevent low engine oil pressure. Over time, engine oil collects dirt and debris, becoming less effective at lubricating. Changing the oil at the manufacturer’s recommended intervals ensures the oil remains clean and effective.

  • Use the Correct Type of Oil: Not just any oil will do for your vehicle. Different engines require different types of oil, which vary in their viscosity, or thickness. Using the wrong type of oil can lead to low oil pressure. Always use the type of oil recommended by your vehicle’s manufacturer.

  • Regularly Check your Oil Level: Checking your engine’s oil level frequently can help detect an issue before it becomes a bigger problem. Some vehicles have an oil pressure gauge in the dashboard; if you notice it’s steadily moving towards a lower reading, it could be a sign of low oil pressure.
