Note: the described vehicles have a function due to which, when it is necessary to change the oil, a warning indicator on the instrument panel turns on. Determining the suitability of an oil for further use in a given system is based on a comparison of many factors. As a rule, the indicator does not turn on before the established oil change interval during maintenance, but it is not recommended to increase this interval, since its reduction has a positive effect on the engine’s service life. If you decide to carry out this type of maintenance in accordance with the indications of the system indicator, after turning it on, you should not exceed a mileage of 16,000 km before changing the oil.
1. Regularly changing the engine oil and filter is the best preventative measure that an amateur mechanic can take when servicing an engine, since over time the engine oil loses its viscosity and becomes saturated with foreign particles, which leads to premature failure of power unit parts.
2. Although some maintenance methods require replacing the filter every second oil change, the creators of the manual recommend replacing it at every oil change, which is due to the comparative cheapness of this element, as well as the ease of replacing it.
3. Before starting this procedure, make sure you have all the necessary tools and equipment (see illustration).
8.3. To change the engine oil and filter, you will need the following accessories and safety equipment: 1. Receiving container - You should select a small but sufficiently sized tray to prevent oil spillage; 2. Rubber gloves - When unscrewing the drain plug and oil filter, protect your hands from getting oil. The gloves also protect against scalding; 3. Extension lever - Sometimes the drain plug is too tight and an extension lever must be used to loosen the tightening force; 4. Socket head - Used to unscrew the drain plug in combination with an extension or conventional lever. The size of the head must match the size of the plug; 5. Device for unscrewing the oil filter - It is a lever with a metal strip that covers the filter around its circumference; 6. Nozzle for unscrewing the oil filter - Installed on the base of the filter, and used in conjunction with a regular or extension lever. Different attachments are used to unscrew different types of filters
4. Also stock up on enough rags and old newspapers to absorb spilled oil. Access to the underbody of the car will be significantly improved if the car is raised on a lift, placed on inclined planes or special supports used after lifting the car with a jack.
Warning: It is prohibited to perform the procedure under a vehicle that is supported only by a hydraulic or conventional jack.
5. Before changing the oil yourself for the first time, locate the oil pan drain plug and lubrication system filter.
6. Warm up the engine to operating temperature. If necessary, while warming up the engine, prepare new engine oil or accessories for use. At the end of this chapter, in the section «Recommended lubricants and fluids», the required type of engine oil is shown.
7. Warming up the engine oil (heated oil with sediment effectively flows out of the system), raise and support the vehicle securely. Make sure that the raised vehicle is securely secured.
8. Remove the mudguard located on the underside of the car. Place the necessary tools under the car, as well as rags and newspapers to absorb the oil. Place a collection container under the pan drain plug. Position the pan accurately, taking into account that the oil will begin to flow out after unscrewing the plug under some pressure, which may change the direction of the stream.
9. Without touching the hot elements of the exhaust system, use an appropriate wrench to unscrew the drain plug, which is located at the bottom of the oil pan (see illustration). The last few turns of the drain plug when unscrewing it from the pan should be done with protective gloves to avoid scalding from hot oil.
8.9. To unscrew the pan plug without rounding its edges, you should use the appropriate spanner wrench or socket head
10. Drain the oil from the engine system into a pan, which may need to be moved as the procedure progresses as the oil flow becomes a trickle in the final stage.
11. After draining the oil, wipe the drain plug with a clean cloth. Even those metal and foreign particles that have accumulated on the plug can immediately contaminate the new oil.
12. Clean the area around the hole and install the drain plug, then tighten it securely. If you have a torque wrench, use it to maintain the required tightening torque.
13. Move a collection container under the oil filter.
14. Loosen the oil filter using a special tool.
8.14. Since the filter is tightened with high force, you will have to use a special unscrewing device; DO NOT use this tool to tighten the new filter during installation
15. Unscrew the filter completely. It should be noted that it is completely filled with oil, which should be carefully drained into a receiving container, and then lower the filter onto the supporting surface.
16. Compare the removed and new filters to ensure they are the same type.
17. Wipe the mounting surface of the oil filter on the cylinder block with a clean cloth. Remains of old oil will smoke when the engine is running, and will also prevent the new filter from being installed properly. Make sure that the old filter gasket is not stuck to the surface of the cylinder block (use a flashlight if necessary). Sticky gasket can be removed using a scraper.
18. Lubricate the rubber gasket of the new filter with clean engine oil (see illustration).
8.18. Before installing a new filter, lubricate its seal with clean engine oil
19. Place the new filter on the cylinder block according to the tightening direction marked on the filter housing or shipping box. Most manufacturers do not recommend using a tool when tightening the filter, as this risks damaging the gasket.
20. Remove any used tools, rags, etc. from under the vehicle, being careful not to spill any used oil from the drain pan, then lower the vehicle onto a supporting surface.
21. Go to the engine compartment and locate the oil filler cap.
22. Pour new oil into the engine through the oil filler neck in the valve cover. Use a funnel to prevent spillage.
23. Fill the system with oil in the amount given in the specifications of this chapter (at the end), using a funnel. Pause for a few minutes to allow the oil to drain into the pan, then check the level on the dipstick (see subsection 4). If the level is near the upper mark, start the engine to begin circulation in the system.
24. Start the engine for one minute, then turn it off. Make sure there is no oil leaking from the pan drain plug and filter.
25. After the poured oil begins to circulate and the filter is filled, recheck the level on the dipstick and top up if necessary.
26. After the first trips made after changing the oil and filter, each time it is necessary to monitor the level and inspect for leaks.
27. Used motor oil is not suitable for use for its intended purpose and must be disposed of. Disposal is carried out by special organizations after the waste oil is delivered there. After the used oil has cooled, drain it into a plastic container and dispose of it. It is prohibited to discharge used oil into the ground or into the sewer.
Oil quality control function in the system
28. This function is provided in the microprocessor of the control system. Based on a comparison of engine speed and temperature in the system control unit, the period for the required oil change is determined. At the same time, the indicator on the instrument panel turns on «Change engine oil».
29. After changing the oil and filter, regardless of the accepted intervals: in accordance with the maintenance schedule given in this manual or when the indicator turns on, it is necessary to reset the system function.
30. To reinstall, you must place the ignition key in the «RUN» (without starting the engine) and within five seconds quickly press/release the accelerator pedal three times. If the indicator blinks for five seconds, the system has been reset correctly. If the indicator does not blink, repeat the reset procedure.
31.If the vehicle has a driver alert display on the instrument panel (DIS), the engine oil quality control system should be reset by pressing the information access button so that an alert is displayed «ENGINE OIL LIFE». After this, you must press and hold the selection button until the system is reinstalled.
