During operation, any engine consumes a certain amount of oil. Therefore, it is important to check the oil level in the engine after certain runs (time intervals) and before a long trip.
For this test, the vehicle must be parked on a level, horizontal surface with the engine off and warmed up to normal operating temperature. If the engine was running before the test, wait a few minutes for the oil to drain into the engine oil pan and allow the oil level to be accurately determined.
Fig. 1.1. Places for checking and filling working fluids and lubricants
Remove the oil level indicator (dipstick), wipe it with a clean cloth and reinsert it all the way into the guide tube. Remove the indicator and check the oil level. The oil level should always be between the MIN and MAX marks (Fig. 1.2)
Fig. 1.2 Checking the engine oil level
If the oil level is below the specified limit, remove the oil filler cap located on the cylinder head cover and add oil. Then check the oil level again. If it is normal, replace the oil filler cap and make sure it is closed tightly and securely.
The viscosity of engine oil changes with temperature. Therefore, it is necessary to select the viscosity of engine oil based on the temperatures at which the vehicle will be operated after the oil change (Fig. 1.3). Selecting a viscosity other than that recommended may cause serious engine damage.

Notes
(1) Engine oil consumption depends largely on the vehicle's payload, engine speed, driving style, etc. and can reach 1.0 l/1000 km.
(2) The technical characteristics (quality) of engine oil can quickly deteriorate when the vehicle is operated under adverse conditions (e.g., when frequently driving on poor roads, in high mountains, on roads with many descents and ascents, and when making numerous short-distance trips). In these cases, the oil should be changed more frequently.
(3) Use only engine oil with API classification not lower than "FOR SERVICE CG".
Warning: It is not recommended to add any additives to motor oil, as this may upset the balance of additives already present in the oil and, as a result, lead to damage to engine components and parts.
