If your car is similar to your body, engine oil is just as important as blood. You do not want to think about what would happen if suddenly you had none. Without engine oil, none of the internal parts would be adequately lubricated for long-term function, which now allows most cars to travel hundreds of thousands of miles without major problems. The engines contain a significant amount of oil in an oil sump (or in a separate reservoir in a dry sump). It is then pumped through the engine to lubricate everything from the crankshaft to the valve gear.
Because engine oil is an important fluid, it is important to ensure that it is kept fresh and changed at the manufacturer's recommended intervals. Through constant use and time, the oil is decomposed and polluted and loses part of its ability to keep things smooth.
Generally, on modern vehicles, you have to change oil every 7,500 miles or every few years (3,000 miles are still there) applies to older models). The factory sets the exact interval. If you are not sure, read the manual. How often you should change your oil also depends on the type of driving and whether you use traditional organic dino oil or artificial synthetic oil. Synthetic usually lasts longer than dino oil and is preferred in most cases.
Oil change in your car can be a dirty job, to say the least. Because of this, many people simply spend the extra money and have the dirty work done by a mechanic or an oil change workshop. But if you do it yourself, you can save a lot of money over the life of your vehicle, and your list of life skills learned will be expanded.
Ready? Let's begin. First, you need to buy enough oil, a new oil filter, and some other simple tools if you do not already have them.
- Jacks or floor ramps [1
- An oil filter wrench
- A washer for the drain plug
- A few rags or a roll of paper towels
- Rubber gloves or latex gloves to fit your Keep hands clean
- An oil drain pan
- A clean funnel
Identify the type of oil your engine needs. This information is usually included in the user manual, but for some new cars it is stamped directly on the oil cover. A common type of oil is 10W-30.
You must then purchase an oil filter and drain plug washer from your local car parts dealer or another dealer. They often have special gears for engine oil and associated filters. As a rule, there is a catalog of buyers next to the shelves with oil filters. There you can look up your vehicle, find the part number of the oil filter and search the item on the shelf.
Step 1: Park your car on a flat surface with plenty of room to work.
Unless you are driving a car with a lot of ground clearance, like a Jeep Wrangler, you will most likely need to lift the end of your vehicle where the engine sits. You want lots of room to work and need to make sure your car is on a level surface so it does not roll when jacking up. Allow the engine to cool sufficiently before starting to drain the oil. Remember that parts like the exhaust become extremely hot.
Step 2: Lift the end of your vehicle where your engine is located A large majority of cars are on the road today. In some sports cars like the Porsche Boxster, it is in the middle, and occasionally it is positioned behind (for example, in a Volkswagen Beetle).
Although many SUVs and trucks have ample space under their frame to carry an oil After conversion, most smaller vehicles have minimal clearance and need to be raised – either by ramp, lift or jack – before you get started can. If using the latter method, make sure that the vehicle is safely on a level surface before climbing under it. Behind the wheels that stay on the ground, laying chocks, is a good idea. In our guide you will learn how to jack up our car here.
Step 3: Locate the oil pan and drain plug
After you are under the car, you need to locate the oil pan and drain plug next. Below you will find the position of the oil drain plug on the bottom of the engine in our 1974 Mercedes-Benz 450SEL restoration project. A 14 mm hexagon socket is required for removal. The size of the oil drain plug varies from car to car.
Place your oil drain pan directly underneath the oil drain plug and ready to catch the oil directly under and a few inches before the stopper. Remove the engine oil cap from the top of the engine to allow the engine to drain the oil more easily by replacing the flowing oil with air.
Step 4: Open the sump drain plug and drain the oil.
Turn the plug counterclockwise (remember: right tight, left loose) with the appropriate size of socket or bit.
It may take a few minutes for the engine to be completely drained, but if the steady flow of oil drips sporadically, you are now ready for the next step. Screw the drain plug clockwise back in and tighten firmly. Do not forget to replace the drain plug washer.
Step 5: Remove the old oil filter and replace it with a new one.
Once most of the oil is available Drain the oil from the engine and replace the oil pan. Find your engine oil filter. It is usually a cylindrical part extending either from the side or bottom of the engine block. On some vehicles, such as certain Subaru models with a flat engine, the oil filter is accessible from the top. However, it is important to note that there are major differences depending on the vehicle and the type of engine. It's much easier to see what an oil filter looks like so you can find it on every engine.
Unscrew the oil filter from the point (again: right tight, left loose) by using one of the two grip pliers or oil filter wrench. Be sure to place the drip pan under the filter, as the oil contained in it may leak out.
Install the new filter after applying some oil to the rubber ring on the edge of the filter. This contributes to a better seal and facilitates removal at the next oil change. Do not overtighten the filter. There is a risk that you will strip the threads on the filter housing, which can lead to significant problems. Handfest is fine in most cases.
Step 6: Add the new oil.
Be quiet, the hardest part is now behind you. Remove the oil cap from your car, take out a funnel and add the required amount of oil to the engine. Make sure there is no leakage from the drain plug or oil filter housing. In this case, tighten the parts as needed.
If your engine needs seven liters, remember to install only seven liters! Too much or too little oil can mean premature death of your engine and turn your car into a very expensive paperweight. Oil is sold either in one-quarter containers or in five-quarter jugs. So, if you need seven liters, you can buy seven single containers or two five-liter jugs, equivalent to 10 liters. Buying the five-gallon cans is usually cheaper and you have a bit more left over to refill between oil changes.
Both types of oil tanks are equipped with scales that allow you to keep track of the amount of oil you pour.
Step 7: Check the oil level, tighten the engine oil cap, and start the engine
After filling the right amount Leave your car for a few minutes while the oil drips into the oil sump. Then check the level with the dipstick of the engine. It is usually located on the side of the engine with a loop that is often painted yellow or red. Wipe the dipstick, replace it in its housing, and remove it again for accurate measurement. Make sure the level is between the indicators etched in the dipstick. If it is too low, slowly add more oil until you reach the right level. If you fill in too much, you should slowly drain it until you have reached the right level.
Now you can start the engine. Let it idle for a minute, turn it off, let it stand for a few minutes, and check the oil one last time. It is also important to monitor the oil pressure gauge in the instrument cluster (if present) during operation. Also pay attention to warning lights on the dashboard. If all goes well, wash your hands and give yourself a well-earned pat on the back.
Do not forget to recycle your waste oil. Pour it into a sealed and portable container and take it to your local car parts dealer or mechanic. There someone will surely and hopefully have it for free.
