Preliminary actions
Park the vehicle on a level, level ground.
Check the engine oil level before starting the engine, but not earlier than 5 minutes after turning off the engine.
Oil
Fill the engine with engine oil only specified by the manufacturer.
If the engine oil level keeps dropping and the engine needs to be topped up frequently, check for engine oil leaks. To do this, when parking the car under the engine, spread a large sheet of paper, and in the morning check for oil stains on the paper, which will determine the leak and its location in the engine. If there are no engine oil leaks, then the engine is worn out, and the oil, getting into the engine cylinders, burns out along with the fuel.
The engine oil level must be between the two marks on the dipstick. If the oil level is low, engine lubrication may be interrupted, resulting in serious engine damage. If the oil level is above normal, the crankshaft sealing ring may fail.

The handle of the dipstick for measuring the oil level is painted in a bright color. Remove the dipstick to measure the engine oil level.

Using a clean rag, wipe the dipstick free of oil residue. Insert the dipstick into the engine and remove it again.

Determine the engine oil level, which should be between the MIN and MAX marks on the dipstick. The amount of oil between the MIN and MAX marks is 1 liter.
