What Causes an Engine Light to Come On When Oil Levels Are Low?

AvatarByCarl Frisch

The engine light is a warning system that alerts the driver of an issue with the vehicle’s engine. A low oil level can be one of the causes of the engine light coming on. When oil levels drop below a certain point, it can cause damage to the engine and result in the illumination of the engine light. To avoid this, it is important to regularly check oil levels and top off as necessary. If the engine light does come on due to a low oil level, topping off should resolve the issue. If not, it is important to have a qualified technician diagnose and repair the underlying problem.

Automobile: Will Low Oil Cause Engine Light to Come On?

Warning Lights and Low Oil

When a driver notices a warning light come on in the car, it is important to take it seriously. The warning light may indicate that the oil level is low and needs to be filled. Low oil can cause major problems in an engine, including permanent damage. It is important to take the time to check the oil level in the car and top off or change the oil as needed.

Potential Causes of Low Oil

There are several potential causes of low oil in a vehicle. One common reason is simply that the oil has been left unchanged for too long, or that it has not been topped up when needed. Other potential causes include leaks or cracks in the engine which can allow oil to escape, or even a faulty seal around the valve cover gasket which can cause a slow drip of oil over time.

Impact of Low Oil on Vehicle Performance

If left unchecked, low oil levels can have a serious impact on vehicle performance. Without enough lubrication, components such as pistons and valves can suffer from excessive wear and tear over time, leading to reduced power output and higher fuel consumption. In some cases, an engine may even seize up due to lack of lubrication if there is no remaining oil left in the system.

Diagnosing the Problem with Low Oil and Engine Light

To diagnose whether or not low oil levels are causing an engine light to come on in a vehicle, there are a few steps that should be taken. Firstly, it is important to check the vehicle’s oil level using the dipstick provided by its manufacturer. If there is still some visible level remaining then topping off with additional motor oil should solve any problems with low lubrication levels within a few miles of driving.

If however, checking reveals that there is no longer any visible level of motor oil remaining then this indicates that something else may be causing an issue with the engine such as worn gaskets or valves. In this case it may be necessary to take it into a mechanic for further diagnosis before topping off with additional motor oil can help resolve any issues with engine performance or warning lights coming on in future use of your vehicle.

Will Low Oil Cause Engine Light to Come On?

Low oil levels can be a major cause of the engine light coming on. If there is too little oil in the system, the vital lubrication needed for the engine components to function properly is reduced. This lack of lubrication can cause internal components to malfunction and lead to an engine light being triggered. It is important to regularly check the oil levels in your vehicle and top up as and when necessary, especially during longer journeys where more oil is used up.

Identifying Engine Code Errors

When the engine light comes on it is possible to identify the exact source of the problem with specific codes or error messages that are stored in a vehicle’s computer system. These codes give a clue as to why the light has been triggered and what needs to be done in order for it to be fixed. A professional mechanic will have access to diagnostic tools that can interpret these codes and provide an accurate analysis of what needs to be done.

Repairing The Problem With Low Oil And Engine Light

The most common repair task that needs to be done when low oil has caused an engine light is simply topping up or replacing the oil completely. This should be done using high quality oil that meets all manufacturer specifications, as this will ensure maximum efficiency and performance from your vehicle’s engine. It may also be necessary to address problems with other vehicle components such as spark plugs or air filters if they are related to low oil levels. Once all repairs have been made, it should then be possible for you or a mechanic to reset the check engine light so that it no longer appears on your dashboard display.

Preventative Maintenance For Avoiding Low Oil And Engine Light Issues

The best way of avoiding low oil issues and having the engine light come on is through preventative maintenance. This involves regularly checking your vehicle’s oil levels and topping up when necessary, as well as checking other vital components such as spark plugs, air filters and any other parts that could affect your car’s performance if they become dirty or worn out over time. Regular servicing by a qualified mechanic can also help keep your car running smoothly while avoiding any unexpected issues with engines lights appearing on your dashboard display.
