Signs Your Car Needs An Oil Change

If you can point out the most important part of your car, then it surely is the engine – and engine oil is what keeps it working in perfect condition.

Remember, your engine is made up of a lot of different parts that are constantly moving and rubbing together. As a result, friction is generated which produces excess heat – the purpose of engine oil is to lubricate these moving parts and remove the resultant heat generated by them.

An oil change is relatively a very straightforward procedure thanks to several workshops present everywhere. In spite of this, many of us either delay or forget to replace engine oil altogether, even though you’re only supposed to change it every 7,500 miles or so if you have a newer model.

With the help of this article, you will be able to better understand the signs that your car needs an oil replacement.

Dark Color Oil

Checking engine oil is a very easy task; you can remove the oil dipstick and see the color of the oil. 

As you run your engine, the parts rubbing each other continuously produce tiny metal specks; these get mixed with oil and start circulating with it. With time and as the oil wears out, these particles continue damaging the engine until you change the oil. 

As a general rule of thumb, new oil is amber colored while old oil is darker in color due to the presence of dirt and metal particles. Hence, if your engine oil is black or dark brown, then consider replacing it as soon as possible.

Excess Noise Generation

Old engine oil tends to become thick and dirty; this causes the engine to make knocking or rumbling sounds as the parts are not being adequately lubricated. 

Worn out oil is detrimental to the overall performance and life of the engine, so if this is the case then consider replacing engine oil right away.

Burnt Smell

If you are regularly experiencing a burnt oil-like smell in your cabin, then you should consider checking the engine oil level. This foul odor maybe because of oil leakage from somewhere onto a hot engine part. 

Smoke Coming Out The Exhaust Pipe

A dark grey or blue color to the car’s exhaust smoke indicates leakage or lower oil levels within the engine. 

Higher Fuel Consumption

If you are experiencing low fuel mileage lately, then the problem could be worn out oil. 

As the oil gets older, it also gets thicker and eventually turns into a slush-like substance. This increases friction within the engine, thus consuming more fuel. 

Car Overheating

The main purpose of engine oil is to lubricate moving parts of the engine and dissipate heat. If the oil level drops, heat generation is substantially increased and causes the vehicle to stop and break down.

Driving with an overheated engine is one of the top maintenance mistakes; it is destructive for the engine as it can lead to a lot of damage, such as warped cylinders or a cracked head gasket. In the long run, these problems could cause your engine to slow down or even stop working entirely. 

So, if your car keeps heating up, then the first thing you should do is check the quantity and quality of oil in your engine.

Oil Warning Light

Probably the easiest indicator of any malfunction in your vehicle is the warning indicator on your dashboard. The oil indicator light – when turned on – usually means that you are low on oil and you need to top-up. 

Cars today come with unlimited types of sensors and newer technology has made it easier for owners to keep track of problems ranging from low battery, transmission fault, etc. As such, if your engine oil warning light is on, then you should change or top it up immediately. 

Vibrations While Idling

When your car needs an oil change, it starts to tremble while idling. This is caused by immense friction between the moving parts of the engine due to the increase in oil viscosity. 

If you are starting to feel these vibrations while idling, then it’s time to check and change your engine oil.

Contrary to popular belief, engine oil change is not solely dependent on mileage as other factors include oil quality, condition of the vehicle and the driving style of the owner. 

Keeping your engine properly lubricated pays off as regular oil change results in less friction, better miles per gallon (MPG) and fewer engine repairs in the future. 

The bottom line is that periodic oil changes – whether they are based on miles covered or months driven – are of utmost importance to the vehicle’s performance and efficiency. They can save you money and add years to the life of your car’s engine. Luckily oil change is a simple task that can be done in your own garage or in an official service center
