1. Put the car on a level ground.
2. Wait at least five minutes when the engine is at operating temperature to allow the oil to drain into the crankcase. Checking the oil level is best done before starting the engine when it is cold.
3. Remove the dipstick. Wipe it with a lint-free cloth or paper towel and reinsert it, then remove it again. If the oil level is between both marks on the dipstick, then everything is in order. If the level reaches only the lower mark on the dipstick, then the oil must be topped up.
With regard to replenishing the volume of engine oil, it is recommended to adhere to the following rule. If the driving style and nature of the movement is moderate, then the oil level should be closer to the lower mark on the dipstick. If the car is constantly operated at high speeds, then the oil level should be maintained higher, i.e. near the top mark on the dipstick.
Filling too much engine oil will adversely affect the engine. The oil level must not be above the MAX mark on the dipstick. It is not recommended to try to fill in so much oil that its level reaches the MAX mark. Excess oil is quickly consumed, then carbon deposits are formed, which adversely affect the operation of the engine and the content of harmful substances in the exhaust gas. Too much engine oil in gasoline-powered vehicles will damage the catalytic converter.
Oil consumption
If the car has a high mileage and it is necessary to replenish the oil in the crankcase frequently, then the oil consumption should be determined.
4. Try to fill in enough oil so that its level is exactly on the top mark of the dipstick.
5. Add engine oil after driving 500 or 1000 km to the original level (up to the top mark), using a measuring container and calculate the flow rate.
Some of the engine oil burns out as a result of friction. Therefore, oil consumption is natural. A well-functioning engine consumes approximately 0.5 liters of oil per 1000 km. The oil consumption of each particular car depends on several factors.
- excess oil leads to an increase in its consumption, because during the ventilation of the crankcase, more oil is carried into the engine.
- low viscosity oil burns faster than higher viscosity oil.
- fast driving style not only leads to increased fuel consumption, but also to increased oil consumption.
- during break-in (earnings) engine oil consumption is slightly higher.
- Engine defects also affect oil consumption, for example, worn valve stem seals, increased play between the valve stem and guide, incorrectly installed piston rings (when replacing) or damaged cylinder wall.
Replacement
You can change the oil yourself, or entrust it to the workshop. It depends on financial capabilities, as well as on the availability of certain skills. As a rule, workshops fill in the most expensive oil.
You can use the services of a gas station by choosing the type of oil yourself.
When changing the oil yourself, be aware that some oil manufacturers use anti-deposit additives. Therefore, before choosing an oil, it is recommended to consult with the workshop.
Attention! The oil filter should also be changed with every oil change.
6. Warm up the engine before draining the oil. To do this, it is enough to drive a short distance (within about 10 minutes).
7. Raise the front of the car.
8. Remove the oil filler cap on the cylinder head.
9. Turn out the drain plug at the bottom of the crankcase, substituting before this a container to collect the oil. Be careful because the oil is hot.
10. After draining the oil, screw in the drain plug, replacing it with a new sealing ring. Tighten the plug with a torque of 25 Nm.
11. Replace oil filter (see relevant chapter).
12. Fill in the prescribed amount of engine oil.
13. Start the engine.
14. Check the oil level and the tightness of the drain plug and oil filter. Add oil if necessary.
