Change car oil filter

Lubrication is essential for the engine because if the lubricating film is damaged, there is a possibility that the pistons will become stuck.

The oil used, nevertheless, needs to be filtered because it isn’t totally pure. This is where the oil filter comes into play; due to its delicate pores, it can trap a significant number of dirt particles.

Change car oil filter

If it is obstructed in any way, it needs to be changed out as soon as possible. In this article, we will discuss how to change the oil filter and what kinds of oils and filters work together to produce the best results.

Why is it so important to replace something?

Due to the pores becoming clogged, an air filter that has seen better days and reached the end of its useful life can no longer filter air at the required level or maintain the necessary flow rate.

In the worst case, they might only filter some or none of the oil. A safety valve is then opened, allowing unfiltered oil to enter the engine area.

Dirt particles can cause minute scratches on the metal if a vehicle with a worn oil filter is used for an extended period

These scratches can eventually lead to the failure of the engine. The time between oil filter replacements can now be substantially longer thanks to recent technological developments.

If you buy a product of sufficient quality, you should be able to rely on its functionality for a distance of up to 37,300 miles.

Identifying features of oil filtration systems

The majority of the air filter’s features, including the thread used and the volume, cannot be discovered because they are indicated by the vehicle’s manufacturer. On the other hand, one can pick and choose from the following features

There are many of them. The former are the ones that are the most convenient to use and can be stored in almost any automobile.

For exchange filter cartridges, you need to have the proper housing, which can be prepared along with the cartridge itself.

  • A check valve helps ensure that oil does not start to flow back into the pump after the engine has been turned off. As a result, there will be less silt, which will speed up the process of restoring the oil flow.
  • Pressure relief valves redress any potential pressure shifts that may occur in the oil pump. This can result in a longer service life; however, in actual practice, these changes will not cause any issues, provided that the pump continues to function normally.
  • Filter paper and adapter assume the primary function and play a significant role in determining the service life. While some distributors provide an explicit indication of the service life, others do not.

Products twith a high-quality level are promoted as such and have a long lifespan. In situations when there is uncertainty, it is advisable to rely on the more well-known brands, even if they are more expensive, or to refer to test results.

The oil that has been used

The oil itself should be changed concurrently with the oil filter replacement. Despite the fact that this is not being said in a formal capacity, it should still be respected.

Finding the ideal oil is practically an exact science, and opinions on the subject are very diverse. The classification and specification of the oil are the two aspects that are most significant (for instance, “15W-40” or “Mercedes Benz 229.1”).

Some are unique to the manufacturer, while others are considered generic. Mineral oils are categorized differently than their synthetic counterparts.

The latter are the ones that are generally regarded as being of higher quality because of their resistance to heat and because they offer superior cold start characteristics.

In addition, there are oils with a high level of lubrication and lubricants with a “long life.”

Due to its characteristics, the former helps minimize fuel consumption by preventing engine load.

The latter are famous for their exceptionally long service lives; however, this characteristic can only manifest if the filter also possesses the requisite durability.

The very nature of the transition itself

The following instruments are necessary for the replacement process:

– The owner’s manual for the automobile

– An appropriate and brand-new oil drain screw

– An oil pan

– A rag

– An elevator with a platform

– Or a ramp or ditch

– Or (emergency solution) a pallet jack

– A resealable plastic bag

– A paintbrush

– A screwdriver, in the event that one is required,

– A wrench, if one is required,

– A wrench for the oil filter, if one is required

Preparation: You need to properly prepare the filter cartridge in case you use one that comes with its housing. Insert the cartridge into the housing along with the ring seals, and then secure the housing using the end caps.

You can securely fasten these in place with the assistance of the air filter wrench. Turn the key to start the vehicle, and then allow it to run for a few minutes.

After turning off the engine, lift the hood to expose the fuel filter and oil filler neck, both of which should be removed now.

Raise the car and look for the screw that controls the oil bleeder. The manual provides directions for assuming this position.

To collect the oil, position a container underneath the bleeder screw.

How to change car oil filter

Step 1

After loosening the bleeder screw using the appropriate tool (a screwdriver or wrench), wait for the oil to stop dripping from the crankcase before closing it.

Along with the used oil, the bleed screw is discarded as well. Put the container to the side, then bring the vehicle down.

Step 2

Put the old filter inside the plastic bag, then take it apart piece by piece.

  • When dealing with spin-on filters, it is necessary to remove the entire housing and wipe the threaded bore clean with a rag. Using the brush, impregnate the cloth with some fresh oil, paying close attention to the process. Additionally, engine oil should be poured into the new filter.
  • In the case of filter cartridges that come with housing, you will need to disassemble the old housing, wipe it down with a rag, and then place the new filter cartridge inside the accommodation along with the ring seals. If you plan to reuse old housing in the future, follow these steps. After that, use a rag to clean the threaded hole, a brush to re-oil it, and oil the filter as well.
  • If the filter cartridge has a fixed housing, you will first need to remove the annular seals and open the housing with the oil filter wrench. Use a cloth to wipe it down. After this, the new filter cartridge should be inserted along with the sealing rings, and then some oil should be added. Secure the housing cover replacement.

Step 3

Lift the vehicle into the air once more, use a towel to wipe away any potential residues from the outlet hole, and then match the new bleed screw with the ring gasket that goes with it.

It would help if you began by manually adjusting them and then using the appropriate tool to give them an additional half-turn of tightening.

Step 4

Reduce the vehicle’s speed and add oil to the point where the top mark on the dipstick is reached, but do not go past that point. After that, reattach the oil filler cap by tightening it.

Step 5

Start the engine, accelerate a few times, and then let the engine run for a few minutes to activate the oil circuit.

Check the oil level using the dipstick once more, and if it needs to be topped off, do so. The oil change is finished if the level of oil is sufficient.

Note: Because waste oil is a potentially harmful substance, it must not be flushed down the toilet or disposed of with other household garbage.

It is required that any items contaminated by the oil be disposed of along with the hazardous waste. Some garages will accept used oil for a fee.

In addition to that, there are buyers of used oil who will occasionally even stop for it. The closest recycling center ought to be your first point of contact.

Possible errors and risks

If you are not careful, changing the oil and the oil filter on your vehicle can be a very messy job.

However, you don’t have to be a handyman or have a lot of knowledge of auto repair in order to complete it.

When working with dangerous materials, there is still a chance that mistakes will be made, and there are also some risks that workers need to be aware of.

Oil Leakage: If your vehicle is dripping with oil after the change, it is possible that the oil filter or the crankcase oil drain screw was not properly installed.

There is also the possibility that the oil filler cap was not installed properly. Check all of the connections that use threading.

Oil level light: For many years, this indicator light has been standard on motor vehicles. It can be found even in modern vehicles that feature an onboard computer.

What is measured differs from manufacturer to manufacturer and model to model. As a result, it may indicate an error after the change.

Don’t worry, it has a habit of switching off by itself within a few minutes at the most. Nevertheless, it is strongly suggested that you go to the workshop just in case, even if this is not the case.

The roadway has been contaminated with significant amounts of oil: It is a disaster waiting to happen because the container was not positioned correctly under the crankcase or because the oil filter was screwed on without paying attention, both of which are dangerous.

You are required to call either the fire department or the citizen protection service if a significant quantity of oil has permeated the street or even in the direction of the sewer.

They contribute to the cleanup and the limitation of the damage. Whoever does not do this and chooses to ignore the oil puddle is committing a crime and runs the risk of being sentenced to prison for their actions.

The chemical can be blended with oil-binding agents in modest amounts, and then disposed of properly.
