Note. Recommended frequency: every 5000 km or 3 months.
Periodic oil and oil filter changes are the most important preventive maintenance procedure. During operation, engine oil ages - it loses its performance properties and becomes contaminated with wear products, which leads to premature engine wear.
Change the oil immediately after driving with the engine still warm, so that the oil flows out faster along with contaminants.
Remove the oil filler cap located on the cylinder head cover.
Raise the car on a lift or place the car in a horizontal position on the inspection ditch.
Pic. 2.5. Unscrewing the engine oil drain plug
Place a container to collect the oil under the drain hole and remove the plug (pic. 2.5). Hold the plug while unscrewing it so that the oil does not leak out prematurely. Wait for the engine oil to drain. When unscrewing the plug and draining the oil, be careful, as the oil has a high temperature.
Visually check the condition of the engine oil for the presence of metal chips and other inclusions.
Clean the oil drain plug with a clean rag.
When the oil is completely drained, wipe the oil around the drain hole and replace the plug with a new O-ring.
Move the oil collection container under the oil filter.
On vehicles up to 2001, the oil filter is accessed from above, and on vehicles since 2001, from below.

Loosen the oil filter with a special wrench, then unscrew it by hand (pic. 2.6, 2.7). After separating the filter from the cylinder block, immediately turn it with the threaded flange upwards to prevent the oil from draining from the filter.

Attention! Be careful when loosening the oil filter as the exhaust manifold is hot.
With a clean rag, wipe the cylinder block from oil spilled when removing the filter, otherwise the oil will burn out and smoke when the engine is running. Also, oil residue will prevent the correct installation and tightening of the new oil filter.
Make sure that no glued fragments of the filter gasket remain on the mating surface of the cylinder block. In this case, remove them with a scraper.
Lubricate the O-ring of the new oil filter with fresh engine oil and tighten the oil filter until the gasket contacts the cylinder block, then tighten the filter 3/4 turn by hand.
Fill the engine with the correct brand of oil. Check the engine oil level after a few minutes. If it is near the FULL mark, close the oil filler cap.
Run the engine for one minute to allow the engine oil to circulate through the engine.
Stop the engine and wait a few minutes for the oil to drain into the sump.
Check the oil level and top up if necessary. Check for oil leaks from under the plug and oil filter, tighten them if necessary.
