An oil filter is an essential part of the internal combustion engine. On this page, more info on replacing the oil filter and fuel filter.
Every engine needs oil to lubricate things, whether it is a diesel or petrol engine does not matter. Some of the engine oil will burn because of the great heat in the combustion engine which requires the oil filter to work. The filter separates the burnt engine oil from the other lubricants and also removes dirt, soot and other particles. If that dirt gets into the engine, the unfiltered oil can damage the engine. Therefore, the oil filter plays a crucial role in ensuring the longevity of the vehicle's engine. Simply put, the oil filter is responsible for keeping the internal combustion engine clean.
Generally, the oil filter is changed between 10 and 25,000 km. But this depends a lot on how often you change the oil and how many miles you drive. You should also remember to change the oil filter together with the oil. To change it, you need a special spanner, consult your car's owner's manual. Long-term use reduces the filter's performance. So regular maintenance is essential for the preservation of your car.
Cause of faulty oil filter
The oil filter fails when its components become dirty or damaged over time. The causes of oil filter failure may be as follows:
If the grease or spare parts used are of poor quality.
If the spare parts used are not suitable.
Improper use of the car engine, such as speeding while the engine is not yet warm.
The oil filter also breaks down if the spring of the part is too tight.
Signs of faulty oil filters
Look for the following signs to recognise a faulty oil filter:
If you notice grease dripping under the engine while parked.
If the oil pressure light on the dashboard is on.
If the oil filter housing becomes swollen.
Changing the oil filter
If you encounter any of the above signs, it is time to replace the oil filter. It is not possible to repair the oil filter. Remember that the filter should be replaced together with the engine oil. Preferably have this done by a specialist in the garage. If the replacement is not done at the right time, it can harm the engine.
There are one or two fuel filters in every vehicle, which should filter the fuel before it enters the injection system. Regular loading and contamination can reduce the fuel filter's performance over time, making it less efficient. Therefore, the fuel filter should be changed frequently to ensure that the fuel is free from contamination.
There are essentially two types of fuel filters - the first is a strainer whose job is to refine the oil going from the fuel pump to the tank. And the second filters the oil back from the fuel tank to the engine.
Fuel filter fault signals
You should pay attention to the following fault signals to replace the fuel filter in time:
Decreasing engine power
Decreasing engine power under acceleration
Difficult terrain conditions cause engine stalling
Regular engine failures
When the engine lights come on
The fuel filter is responsible for removing dirt from the fuel for efficient operation. Clogging in the filters is often noticed only through improper engine function and reduced power. If you encounter any of the above symptoms, it could mean it is time to replace the fuel filter.
Replace fuel filter
Although most fuel filters have a lifetime guarantee for fuel filter maintenance, a second fuel filter should be replaced regularly as it has a shorter service life than the primary fuel filter.
The primary filter lasts about 150,000 km, while the other fuel filter should be replaced every 60,000 km.
To replace the fuel filter, it is best to visit a mechanic at the nearby garage or follow the following steps:
Disconnect the fuel line from the MPFI engine and reduce the inlet pressure of the electronic fuel pump.
Make sure the engine is in neutral and the handbrake is on. Now start the engine and reduce the pressure in the fuel line.
Now turn off the engine as soon as the pressure decreases. Refer to the user manual and follow the instructions. For safety reasons, remove the pump fuse from the fuse box. If this requires additional tools, it is best to go to specialist garage.
Before attaching the fuel filter - check the slot mark on the new filter compared to the old one. And attach it accordingly.
Secure the filter by tightening the screws, nuts and bolts. Replace the pump fuse in the fuse box.
In the following text, we describe how to measure the oil level of the Opel Karl and how to fill in the correct oil when the oil light comes on.
Which Opel Karl engine oil?
The various engines of the Opel Karl should always be filled with engine oil approved by the manufacturer - we recommend a 5W30 oil for most Opel Karl engines.
Always ensure that your chosen oil can be used in your vehicle by checking the year of manufacture of your Opel Karl and engine data. If in doubt, it is best to check your car's instruction manual.
How to measure the oil level on Opel Karl (oil light on)
If the oil light (note: not the low oil pressure warning light) comes on in your Opel Karl, drive slowly and at low speed to the nearest petrol station, garage or hardware store so you can measure the oil and top it up if necessary.
Make sure your vehicle is as horizontal as possible (not on a slope or hill).
Then switch off the engine.
Then wait for about 3-5 minutes before checking the oil level. This allows the engine oil to drain back from the pipes.
Now you can open the Opel Karl hood.
In the engine compartment, you will find the so-called oil dipstick of the Opel Karl. Pull the dipstick out of its holder.
Now clean the dipstick with a cloth, handkerchief or toilet paper.
Now place the clean rod back in the holder.
Now pull out the stick.
The oil level must be between the "minimum" and "maximum" marks.
If this is not the case, the vehicle should always be filled with suitable Opel Karl engine oil.
Instruction on how to refill engine oil Opel Karl
Buy suitable oil for your Opel Karl.
Open the bonnet and check the oil level (instructions above).
Now slowly fill a small amount (approx. 100ml) into the Opel Karl oil nozzle.
Now wait a few minutes before measuring the oil level again.
Do not restart the Opel Karl until the engine oil level is between the "Min" and "Max" marks.
Also check the oil level at the next Vauxhall Karl inspection or an upcoming oil change to make sure everything is in order.
On this page you will find information about the Peugeot 207 engine oil. We show you how to measure the oil level of the Peugeot 207 and how to pour suitable engine oil into the oil filler hole when the oil lamp lights up. In addition, we examine some types of oil that are suitable for the engines of the Peugeot 207.
Which Peugeot 207 engine oil?
Looking for a suitable engine oil for the Peugeot 207? At the bottom of this page you will find an overview of all models and the corresponding oil. Always make sure that the oil you choose is suitable for your vehicle, given the year of manufacture of your Peugeot 207. In many cases, 5W-30 or 0W-30 is suitable, but to be sure, you can best look it up in your service booklet or via the table at the bottom of this page.
Measuring the oil level in Peugeot 207 (oil light on)
If the oil warning light (note: not the low oil pressure warning light) comes on in your Peugeot 207, drive straight to the nearest petrol station, garage or DIY store (albeit at low speed and revs). And buy a new and suitable engine oil.
Make sure your car is not on a slope or hill.
Then switch off the engine with the ignition key or the start button.
Wait about 5 minutes before checking the oil level. This allows the engine oil to flow out of the engine and back into the oil sump.
Now you can open the bonnet of the Peugeot 207.
In the middle of the engine compartment you should see a pull-out dipstick.
Pull the dipstick out of its holder.
Clean it with a handkerchief.
Then replace the cleaned oil dipstick in the holder.
Now pull it out of the hole again.
The oil film must be in the centre of the "Min" and "Max" marks.
Should this not be the case, it is always necessary to top up with engine oil suitable for the Peugeot 207.
