During operation, engine oil ages – it becomes liquid and contaminated, which leads to premature engine wear.
The oil should be changed immediately after driving, with the engine still warm, so that the oil and any contaminants drain better.
To change the oil and oil filter, you must use the following equipment and materials:
- motor oil of the appropriate specification;
- oil filter;
- new sealing ring for the oil drain plug;
- 6 liter capacity container for collecting used oil (you can use an old oil can with the side wall cut off or a basin that has served its time);
- waste oil disposal container;
- funnel for pouring fresh oil;
- open-end strap wrench for removing oil filters;
- a wrench for loosening and tightening the oil drain plug.

You will also need plenty of clean rags and newspapers to wipe up any spills.
Warm up the engine to normal operating temperature.
Remove the cap from the oil filler neck located on the cylinder head cover.
Raise the vehicle on a lift or place it horizontally on an inspection pit.
Warning! Do not work under a vehicle supported only by a jack.
Place a container to collect the oil under the oil drain hole and unscrew the plug. If necessary, apply pressure to the cap while unscrewing; to prevent oil from leaking out prematurely, drain the engine oil. When removing the plug and draining the oil, be careful as the oil is hot.
Visually inspect the engine oil for metal shavings and other inclusions.
Clean the oil drain plug with a clean rag.
Once the oil has completely drained, wipe away any oil around the drain hole and screw in the drain plug with a new sealing ring.
Move the oil collection container under the oil filter.
Use a special wrench to loosen the oil filter, then unscrew it by hand. After separating the filter from the cylinder block, immediately turn it with the threaded flange facing up to prevent oil from draining from the filter.
Use a clean rag to wipe the cylinder block to remove any oil spilled when removing the filter, otherwise the oil will burn off and smoke when the engine is running. Oil residue will prevent the new oil filter from installing and tightening properly.
Make sure that there are no remaining glued fragments of the filter gasket on the mating surface of the cylinder block. Otherwise, remove them with a scraper.
Lubricate the O-ring of the new oil filter with fresh engine oil and screw the oil filter in until the gasket contacts the cylinder block, then tighten the filter an additional 3/4 of a turn.
Fill the engine with oil of the appropriate grade. After a few minutes, check the engine oil level and, if it is near the "F" mark, close the oil filler cap.
Run the engine for one minute to allow the engine oil to begin circulating through the engine.
Stop the engine and wait a little while for the oil to drain into the pan.
Check the oil level and top up if necessary. Check for oil leaks from the plug and oil filter, otherwise tighten the fasteners. On models with an oil cooler, also check for leaks between the oil cooler and the engine block. If leaks are found, remove the oil cooler and replace the seal.
