Changing the engine oil

Changing the engine oil 1

Engine oil change

It is necessary to change the oil in the car in accordance with the schedule provided by its manufacturer. Change your oil more often if you make frequent short trips or if you have to drive through a dusty, dusty area. This is how oil changes..

Required Skill Level: Intermediate

Time Required: 60 minutes

Inspect your vehicle. Look under the hood and inspect the engine. Do you know where the oil filter is located? Most of them are made in the form of a box and you will need a wrench. On some cars (BMW immediately comes to mind) there is a filter made in the form of a cartridge, for which you need a combined set of keys. When inspecting, follow these instructions:

1. Can you fit under a car with a tank for draining used oil and then get this tank and oil filter? If not, then you will need to drive the car to the observation deck (ramp).
2. Under the car is quite dark. Do you have a small flashlight? If not, you will need to buy it.
3. Visually identify where the hole for draining engine oil is located and be careful. Look at the metal pan of the crankcase, which looks like the bottom of the faucet sink – this is the crankcase.
4. Make sure that your key fits the size of the oil pan plug. If not, you will need to buy a set of keys or just one key that fits the size.
5. Do not forget to take a special pan to drain the used oil into it. You can use a large plastic tray or a plastic box for cat food, or a plastic bath, which is specially made to collect waste oils. Perhaps she will have a groove to make it easier to drain the used oil into a canister.
6. The most difficult part of “inspecting” a car can be finding the oil filter. In cars of old models you can easily see it. Newer models have pads or shields that close the filter. Often there are sliding shields. They must be moved to the side to get to the filter. How to do it, read the “Instructions for the car”.
7. Do not be surprised if you have to bend and twist your arm like an acrobat, which depicts a snake, in order to get to the filter.

Summarizing the above, you should determine where the oil filter and the oil pan drain plug are located. Make sure that you are able to perform this work and then proceed to the following operations.

Tools that will be required in the work

Oil filter wrench, combination wrench, flashlight, overpass (if needed), funnel, rubber gloves, rags, newspaper and 5 liter canister.

Before you go to the spare parts store, read the Instructions for your car. In it you will find data on the viscosity and quality of engine oil for your car. It may also contain information about the oil filter. And although this is obvious, but, nevertheless, accurately find out the release date, model and engine data of your car. You can also take advantage of our special program and select a specific oil for any unit of your car, find out the volume of the system, as well as a convenient place of purchase.

And now it’s time to go to the parts store. You should write down what you need in case you are new to this business. Instead of pretending that you know everything, it will be better to approach the seller and explain your problems. Perhaps the seller of spare parts for the car will be able to tell you exactly what size the key is and if there are any other features when performing this operation.

Much more depends on the quality of the oil itself than on its viscosity. You will find a lot of information about this on other pages of our website on the Internet..
Summarizing the above, we note: buy only the recommended oil and oil filter.

Depending on what the results of the preparation work are, the car can stand on the overpass, if necessary, at the first speed (or in the parking mode if you have an automatic transmission) and with the hand brake applied. Make sure the front wheels are properly mounted on the flyover. You must follow all safety precautions. Remember that each time you are under the machine, two tons of the machine’s weight hang above you. And the consequences here will not end simply by removing the skin from your finger. Therefore, be doubly vigilant. Double check everything. The machine should stand on a flat hard surface, best on asphalt or concrete pavement.

1. While the engine is running, the oil will be hot. But you do not want to deal with hot oil. Therefore, after you have entered the overpass by car, turn off the engine and leave it for 15-30 minutes before starting work.

2. Rubber gloves are very suitable for this work. They are disposable. They will allow your hands to remain clean, and with their help you can better hold individual objects in your hands. Now is the time to put them on. Taking into account that you have already previously removed all the covers or hinged hatches that blocked access to the engine, you just have to dive under the car, taking with you:
1. The keys you need
2. Tray for draining used oil
3. Paper towel / rags
4. Newspaper.

3. Place a container to drain the oil under the oil pan. When the first used oil is poured out, it will be pulled out of the hole with great force, so you should consider the possibility that the oil will spill not only directly down, but also spray on the sides (sawdust or litter is great for collecting oil leaks).

4. Using the key of the required size, loosen the oil pan plug by turning it counterclockwise and carefully monitor it. Is there a plastic or metal gasket on it? It happens that some gaskets “stick” to the oil pan, while others just go away with the cork. In the most unpleasant case, they can jump out and fall into the used oil (after that you will need fishing skills!). Be prepared for such a development.

5. After you have sufficiently unscrewed the plug, unscrew it by hand further, holding it all the time with sufficient force to contain the oil pressure from the oil pan. Keep turning the cork very slowly, checking from time to time to see if you have completely unscrewed it. After you have made sure that the plug is completely unscrewed from the oil pan, quickly move your hand with the plug to the side.

6. Place the oil drain pan on the newspaper and keep an eye on how the oil flows out all the time. All waste oil should only be poured into this container..

7. While oil is draining from the oil pan, spend some time looking at the location of the oil filter. See if there is a cover or hatch that needs to be removed to gain access to the filter. Use a paper towel or rag to wipe the outside of the box to make it easier for you to tackle it..

8. Before using the tools, try unscrewing the oil filter by hand. Maybe you are lucky and he will succumb. Stop! Stop immediately and do not crank it more than 2-3 cm. And now all the oil should have already leaked onto the sump. Slide the oil pan under the oil filter and then reinstall the drain plug. Tighten it gently and firmly with a wrench, stronger than you would do it manually. (However, do not get too carried away if you do not want to tear off the threads of the oil pan). In total, a pressure of 10-13 kg is needed so that the cork is properly tightened.

9. While the used oil pan is in a new position, install a special key with a belt around the oil filter and try to loosen it. Be patient and do not rush if you are unable to do this on the first try. If it was not possible for the first time, reinstall the key with the belt and try, leaning with your whole body, make more effort.

When it’s not too late to stop!

If you are unable to remove the oil filter, you should stop before you break anything. Make sure that the filter is still firmly fixed, then fill the engine with the recommended amount of oil and take the vehicle to a repair shop or dealer so that they can change the oil.

10. After you have loosened the oil filter half a turn, remove the key. You must be able to unscrew the filter by hand. Now you must balance! You want to hold the filter as long as possible in order to transfer it to the used oil pan, and at the same time you do not want to spill the oil that is in the filter. But regardless of your plans, as soon as you remove the filter, the oil may spill over the edge and fall onto the underlying parts. Get ready with the pallet! After you have just removed the filter, try to place it (without dropping it!) Directly on the used oil pan.

11. Wipe off any drips and spilled oil with a paper towel, get out from under the machine. Then bend again to slowly pull out the sump with the drained waste oil. Be careful not to spill it..

12. Prepare a new oil filter for installation by dipping your fingertips into the used oil (After all, you have rubber gloves on your hands, right?). And then apply a thin layer of oil film to the rubber gasket, which is located at the bottom of the new oil filter.

13. Go back under the car and put a new filter at the bottom of the newspaper (the gasket should be vertical). Before installing a new filter, check if the flange on which the filter is mounted is damaged. To do this, slide your finger over its surface. Make sure that the rubber gasket from the old filter is still not on the flange. Any significant dents in the flange where the filter will be installed can result in oil leakage. And if you find them, do not try to repair (replace this flange yourself). Just take this fact for yourself and remind yourself of this during the next service of your machine..

14. Replace the new oil filter. Try to remember the installation angle of the old filter. Connect the new filter to the mounting flange and carefully “thread” the new filter onto the threads. Fix it according to the manufacturer’s recommendations (which are usually listed directly on the box).

15. Replace the cover or hatch that you removed at the beginning of installation. Clean the surface around the lid guides or other contaminated areas where oil has spilled. You can not use soap and water – a small oil film on the parts of the chassis does not hurt at all. Just make sure that there are no oil smudges.

16. Get out from under the car and raise the hood. Install the location of the oil filler cap. To verify that it is correct, refer to the “Operation Guide”. It also usually explains in detail which oil to use and even provides recommendations for its viscosity. The “Instruction Manual” usually also indicates the amount of oil that you will need. In the event that you installed the car on a flyover and cannot get to the lid for oil filling, use a small stand for this purpose. DO NOT start the engine until you have added oil to it!

17. Unscrew the oil filter cover and carefully fill in new oil. Use a funnel to avoid splashing oil.

18. Fill in the correct amount of oil. The norm is the use of three and a half to six liters of oil – and again, refer to the “Operation Guide”. It is important not to pour more oil than necessary. Replace the cover..

19. Now clean all oil stains under the hood. And after you have removed all the rags and paper towels from under the hood, you can start the engine. DO NOT increase engine speed! Wait until the oil indicator or instrument showing the oil pressure is set to the “normal” position. Let the engine idle while you exit the car and check for oil leaks. Use a flashlight for this. Look under the hood and under the car (but do not crawl under the car with the engine running).

20. Shut off the engine. Remove all tools from under the vehicle. Check if you have left anything under the car or under the hood.

21. Start the engine again, and carefully exit the flyover. No need to check the oil.

1. Wipe all tools and place them in the tool box. Take out the old oil filter and hold it until all the used oil drains into the sump.

2. Very carefully drain used oil into a suitable container. Use a funnel if necessary. Often this work is best done with an assistant, so ask someone to help you. Do not forget to make a clear inscription on the container (using adhesive tape for marking and a felt-tip pen) and then return it for recycling. If you don’t know where, then ask your local authorities for recycling used engine oil. It is very important that you do not pour any other liquids into the container in which the used engine oil is stored. If you mix it with other substances, then later this oil will not be able to process.

3. Now check the oil level in the car and do the final adjustment work, if necessary. And remember: in no case should you pour more oil than you should!

4. And while you remember this, take the car to a local oil processing plant or service station and return the used oil. It’s better than storing it at home or throwing it away anywhere.
