How to Replace an Oil Filter

Almost 70% of drivers don’t know how to change their oil. In fact it is a task that is needed after every 6000 miles or 6 months, whichever comes first. Most of the drivers drive with dirty and old oil which can result in engine degradation. It is not very difficult to change an oil filter and it can be done in DIY style, here is a simple guide. Follow the directions.

Things Needed

  • New oil filter
  • New oil
  • New oil cap
  • Wheelie board
  • Axle stands
  • Container for old oil
  • Jack

Oil Filter

  • Latex Gloves
  • Chain wrench
  • Spanner or socket set to fit sump plug


Step 1:

An oil change should not be done within two hours time period of driving the car. Otherwise the dipstick will not show correct reading. A good idea is to run the engine with low revs for couple of minutes before thinning the oil and aiding the oil drain.

Step 2:

The car should be parked on a flat surface; this will ensure the stability of the jack.

Step 3:

Open the car’s bonnet and remove the oil filler cap. It is usually made of plastic and is located on the engine block at the top. Check the air vents in the cap for any blockages, replace the entire cap if they are blocked.

Step 4:

The next step is to locate the oil filter and the sump plug. The sump plug looks like a bolt-head which is usually hexagonal and faces downwards or sideways, it is usually located at the rear of the engine. In case these are easily accessible without putting the car on a jack, then skip the steps 5 and 13.

Step 5:

The car has to be raised on a jack from the front end. Leaving the weight of your car resting on the jack for any length of time is not recommended. Thus placing the axle stands under the front axles is important is a double safety measure.

Step 6:

Start unscrewing the sump plug anticlockwise with the spanner/socket set and make the container ready to catch the pouring oil. Make sure that your head is not directly under the plug.

Step 7:

Rotate the sump plug taking it off by hand and let the oil drain down in to the old oil container. Keep observing the container as the oil flow likely moves. The drained oil should be disposed off properly by taking it to a garage of a disposal site.

Step 8:

The sump plug has a magnetic tip. The oil should be gently wiped off and observe it. If the tip has lots of small metal filings, this is a sign that the engine is degrading. There can be number of reasons for this including rust. Make sure the oil is frequently changed in future; this will ensure the safety of the engine. Some sump plugs have a washer for ensuring a better seal. Make sure this does not fall off and replace it if it looks at all damaged.

Step 9:

The oil filter has to be unscrewed anti-clockwise. Hands can be used but a chain wrench is mostly used.

Step 10:

Wipe a thin layer of oil around the rubber seal of the new oil filter for ensuring a perfect contact. Then screw the new filter and tighten it by hand only. Avoid over-tight because the threads can break.

Step 11:

The oil should have completely draining by this point. Replace and tighten the sump plug roughly one half-turn past with the spanner/socket set.

Step 12:

Now the jack and axle stands can be removed and bring the car back to a level position.

Step 13:

Locate and remove the dipstick, wipe off the old oil and replace it.

Step 14:

Now pour the new engine oil and take an interval after a pint or 30 seconds, then check the level of the dipstick. Keep pouring till the oil reaches the upper level on the dipstick.

Step 15:

Finally, replace the engine oil-filler cap.

Step 16:

Now, start and run the engine for few minutes to check the performance.
