The oil filter is responsible for filtering the oil that lubricates the components of your engine. As oil circulates through the engine, it picks up contaminants and debris along the way. You’ll want to keep these contaminants out of the engine to preserve its lifespan. The only way to keep out the contaminants is to have an oil filter which can prevent them from entering the engine. The engine depends on the filter just as much as it depends on the oil itself. If you had no oil filter in your vehicle, then the contaminants will build up rather quickly inside the engine. This will create a whole lot of functionality issues in the engine and the vehicle.
The Top 5 Symptoms
Most car owners never need to worry about changing the oil filter because it can usually last for a long time. However, if you notice certain symptoms occurring in your vehicle, then it will be a sign that you do need to replace your oil filter with a new one. Otherwise, you could risk permanent damage to your engine which will cost thousands of dollars to replace.
Below are the top 5 symptoms of a bad oil filter in your car. As soon as you recognize these symptoms, get your vehicle to the nearest auto mechanic so that they can replace the filter for you.
Engine Overheated – Sometimes you might have a clogged oil filter. This could be an even worse problem because it may prevent oil from being able to enter the engine altogether. Once that happens, the engine will not receive any lubrication for its moving components. As you know, the friction between the metal components will generate heat quickly. If this heat cannot be cooled by the oil, then it could lead to the engine overheating. You should see the “Check Engine” light come on when this happens.
Weak Performance – The performance of your vehicle will tell you more than enough. If contaminants are building up in your engine because the oil isn’t being filtered properly, then it will diminish the engine’s ability to generate power for the vehicle. This means that when you step on the gas pedal, your acceleration will be reduced or nonexistent. As you continue to let this problem go unfixed, the performance will only get worse.
Dirty Exhaust Fumes – Take a look at the exhaust fumes coming out of your vehicle’s tailpipe. Does the exhaust smoke look dirty at all? If the exhaust looks brown or black, then it is definitely dirty. This is the result of a clogged oil filter causing oil to flow into your exhaust system. You may even experience a burning odor inside your vehicle from this too. These are very obvious signs that you need to replace your filter promptly.
Low Oil Pressure – The dashboard of your vehicle should have an oil pressure gauge. In normal situations, the gauge will show a consistent amount of oil pressure that will never change. But if you see the oil pressure dropping erratically as you’re driving, then you definitely have a problem with your oil pressure. Most likely, this is caused by a clogged oil filter which is preventing the flow of oil from going into your engine.
Metallic Noises – When oil is prevented from entering your engine and all those metal components grind against each other, all that friction will cause two things to happen. Like previously mentioned, it will cause the engine to overheat. But it will also cause a lot of metallic noises to occur as a result of the grinding. These noises should be very easy to hear as you’re driving.
