Can Oil Cause Check Engine Light?
The Check Engine Light is a common issue that many car owners face, and it can be a source of frustration and anxiety. When the Check Engine Light comes on, it can indicate a wide range of problems, from minor issues to serious safety concerns. One question that often comes up is whether oil can cause the Check Engine Light to come on. In this comprehensive blog post, we will explore the relationship between oil and the Check Engine Light, and provide answers to this question.
The Check Engine Light is a critical component of a vehicle’s onboard diagnostics (OBD) system, which is designed to monitor the engine’s performance and detect any problems. When the OBD system detects a fault, it triggers the Check Engine Light to come on. The light can be caused by a variety of factors, including faulty sensors, ignition system problems, and engine mechanical issues.
Oil is a critical component of a vehicle’s engine, and it plays a vital role in lubricating the moving parts and keeping the engine running smoothly. However, oil can also be a source of problems if it is not maintained properly. In this blog post, we will explore the ways in which oil can cause the Check Engine Light to come on, and provide tips on how to prevent and diagnose these issues.
Can Low Oil Pressure Cause the Check Engine Light to Come On?
Low oil pressure is a common issue that can cause the Check Engine Light to come on. When the oil pressure is low, it can indicate a problem with the oil pump, oil filter, or engine mechanical issues. If the oil pressure is too low, it can cause the engine to overheat, leading to serious damage and potentially causing the Check Engine Light to come on.
The oil pressure sensor is a critical component of the OBD system, and it monitors the oil pressure in real-time. If the oil pressure sensor detects a problem, it can trigger the Check Engine Light to come on. In some cases, the Check Engine Light may come on with a specific code, such as P0520, which indicates a low oil pressure problem.
To diagnose a low oil pressure problem, you can check the oil level and pressure using a dipstick or a pressure gauge. If the oil level is low, you can top it off with the recommended type of oil. If the oil pressure is low, you may need to replace the oil pump or oil filter, or address any engine mechanical issues that may be causing the problem.
Causes of Low Oil Pressure:
- Worn or damaged oil pump
- Clogged or dirty oil filter
- Low oil level
- Engine mechanical issues, such as worn or damaged piston rings or cylinder walls
- Oil leaks or contamination
Symptoms of Low Oil Pressure:
- Check Engine Light comes on
- Oil pressure gauge reading is low
- Engine overheats
- Oil leaks or spills
- Engine makes unusual noises or vibrations
Can Dirty Oil Cause the Check Engine Light to Come On?
Dirty oil can cause the Check Engine Light to come on if it is not changed regularly. When oil becomes dirty, it can break down and lose its lubricating properties, leading to engine damage and potentially causing the Check Engine Light to come on.

The oil filter is designed to remove contaminants and debris from the oil, but if it becomes clogged or dirty, it can allow dirt and debris to enter the engine. This can cause a range of problems, including engine overheating, oil leaks, and engine mechanical issues.
To diagnose a dirty oil problem, you can check the oil level and condition using a dipstick or a oil analysis kit. If the oil is dirty or contaminated, you may need to change the oil and oil filter, or address any engine mechanical issues that may be causing the problem.
Causes of Dirty Oil:
- Infrequent oil changes
- Driving in extreme temperatures
- Driving in stop-and-go traffic
- Driving with a heavy load
- Using the wrong type of oil
Symptoms of Dirty Oil:
- Check Engine Light comes on
- Oil level is low
- Engine overheats
- Oil leaks or spills
- Engine makes unusual noises or vibrations
Can Oil Leaks Cause the Check Engine Light to Come On?
Oil leaks can cause the Check Engine Light to come on if they are not addressed promptly. When oil leaks occur, it can cause a range of problems, including engine overheating, oil contamination, and engine mechanical issues.
The oil leak sensor is a critical component of the OBD system, and it monitors the oil level and pressure in real-time. If the oil leak sensor detects a problem, it can trigger the Check Engine Light to come on. In some cases, the Check Engine Light may come on with a specific code, such as P0572, which indicates an oil leak problem.
To diagnose an oil leak problem, you can check the oil level and condition using a dipstick or an oil analysis kit. If the oil level is low or the oil is contaminated, you may need to replace the oil pan gasket or oil seal, or address any engine mechanical issues that may be causing the problem.
Causes of Oil Leaks:
- Worn or damaged oil pan gasket
- Worn or damaged oil seal
- Loose or damaged oil drain plug
- Oil filter is clogged or dirty
- Engine mechanical issues, such as worn or damaged piston rings or cylinder walls
Symptoms of Oil Leaks:
- Check Engine Light comes on
- Oil level is low
- Oil leaks or spills
- Engine overheats
- Engine makes unusual noises or vibrations
Can Using the Wrong Type of Oil Cause the Check Engine Light to Come On?
Using the wrong type of oil can cause the Check Engine Light to come on if it is not compatible with the engine. When the wrong type of oil is used, it can cause a range of problems, including engine overheating, oil contamination, and engine mechanical issues.
The engine oil viscosity is critical in determining the type of oil to use. If the wrong type of oil is used, it can cause the engine to overheat, leading to serious damage and potentially causing the Check Engine Light to come on.

To diagnose a problem with the wrong type of oil, you can check the owner’s manual or consult with a mechanic. If the wrong type of oil is used, you may need to drain and replace the oil, or address any engine mechanical issues that may be causing the problem.
Causes of Using the Wrong Type of Oil:
- Using the wrong viscosity of oil
- Using the wrong type of oil for the engine
- Not checking the owner’s manual
- Not consulting with a mechanic
- Using counterfeit or fake oil
Symptoms of Using the Wrong Type of Oil:
- Check Engine Light comes on
- Engine overheats
- Oil level is low
- Oil leaks or spills
- Engine makes unusual noises or vibrations
