Caution: If the maintenance procedure has not been followed for a long time, the following checks and adjustments should be performed as necessary.
Changing the oil and filter on time are the most important preventative maintenance activities that an owner can perform on their own. As the oil in an engine ages, it becomes thinner and more contaminated, which leads to premature engine wear.
Before changing the oil, prepare all the necessary tools and materials. It is best to drain the oil on a warm engine, since hot oil is quickly and completely removed from the engine, taking contaminants with it. The work is significantly simplified if the car is on a ramp, inspection pit, or lifted on a jack and installed on supports. When changing the oil, the horizontal position of the car must be maintained, regardless of the lifting method, or such a position in which the drain plug of the pan is at the lowest point.
1. Unscrew the oil filler cap on the cylinder head cover.
2. Loosen the drain plug by about 1/2 turn. Place a container under the plug and completely unscrew the plug. Remove the sealing ring from the plug.
3. Drain the oil by gradually moving the pan closer to the drain hole.
4. Wipe the plug and sealing ring clean. Check the condition of the sealing ring, replace it if damaged. Wipe the surface of the tray around the drain hole, put the ring on, screw in and tighten the plug to the specified torque.
5. The oil filter is located on the right side of the cylinder block, at the rear. Access to the filter is provided from below.

6. Place a container under the filter.
7. Loosen the filter with a special key, then unscrew the filter by hand. Drain the oil from the filter into a container.
8. Wipe clean the filter seal area on the engine, removing any remaining oil and dirt. Inspect the used filter, check for a gasket that may have stuck to the cylinder block, and remove the gasket.
9. Lightly lubricate the new filter gasket with fresh engine oil and screw the filter in. Once the gasket has made contact with the cylinder block surface, pull the filter slightly, then tighten it 2/3 of a turn.
10. Remove the container with the drained oil and the tool from under the car and lower the car.
11. Fill in half the required volume of oil. Wait about 2 minutes for the oil to drain into the pan. Continue pouring oil in small portions until the level reaches the lower mark on the dipstick. Bring the level to the upper mark on the dipstick by adding about 1.0 liter of oil.
12. Start the engine and watch for leaks around the oil filter and drain plug for two minutes. Keep in mind that the oil pressure warning light will go out a few seconds after the engine starts, i.e. after the time it takes to fill the oil filter and oil passages. Until the light goes out, the engine should only idle.
13. Stop the engine, check the oil level again after two minutes, and top up if necessary.
