For better control over the condition and operation of the engine, it is recommended to fill in engine oil of the same type and brand. With cotton wool, it is recommended that after each oil change, a plate be installed indicating the brand and viscosity of the filled oil.
6.0. Viscosity classes of motor oils: A - light all-weather motor oils; B - all-weather motor oils
The indiscriminate use of oils of different types adversely affects the condition of the engine. If possible, do not mix engine oils of the same type, but different brands. If necessary, you can safely mix oil of the same brand and type, but of different viscosities (see illustrations 6.0 and 6.0a).

Checking the engine oil level
Attention! Per 1,000 km of run, oil consumption is allowed no more than 1 liter. Exceeding this volume indicates wear of the oil seals and / or piston rings.
1. Warm up the engine and place the car on a level surface.
2. Stop the engine and wait approximately 3 minutes to allow the oil to drain into the sump.
3. Pull out the oil dipstick (probe) and wipe it dry with a clean cloth.
4. Insert the dipstick all the way into place, and then pull it out again and check the oil level.
The engine oil level is normal if it is within the designation on the dipstick «b».If the oil level is near the mark «With», then the oil must be added (see illustration).
6.4 The engine oil level is normal if it is within the designation on the dipstick «b». If the oil level is near the mark «With», the oil must be topped up. The illustration shows both dipsticks used on Audi vehicles
Attention! If the oil level is above the mark «A» (see illustration 6.4), then the excess oil should be taken away, because this can lead to damage to the seals or the catalyst.
If the engine is heavily stressed, such as long motorway trips in the summer, with a trailer or in mountainous terrain, the oil level should be at the top of the dipstick.
5. Fill in oil through the oil filler neck in the cylinder head cover. Use only types and brands of oils recommended by the manufacturer, do not use any additives.
6. Replace the dipstick and screw the cap onto the filler neck.
Draining engine oil
7. Cars with a diesel engine. Unscrew the oil filter cap with a 32mm socket wrench or socket head (see arrow in illustration). Before doing this, remove the top protective cover of the engine. After unscrewing the cap, the oil will flow out of the filter.
6.7. Unscrew the oil filter cap with a 32mm socket wrench or socket head (see arrow). Diesel vehicles
8. Take the oil with a siphon through the guide tube of the rod indicator (probe) oil level. If there is no siphon for oil extraction, then drain the oil by placing the car horizontally on the goats.
9. Remove the engine mudguard.
10. Place a container under the drain hole of the sump to collect used oil.
11. Unscrew the screw plug from the drain hole on the oil pan and allow the oil to drain.
Attention! If a large amount of metal chips and metal abrasion products are found in engine oil, then this indicates the presence of scoring, for example, in crankshaft bearings or connecting rod bearings. To avoid further damage, the oil passages and oil circulation hoses must be thoroughly cleaned after the engine has been overhauled.
As an additional measure, if installed, replace the oil cooler.
12. After draining the oil, screw the plug into the drain hole, replacing its old sealing ring with a new one. Do not over tighten the drain plug. Otherwise, oil leakage or thread damage may occur.
Tightening torques for the drain plug:
- cars with a 6-cylinder engine - 40 Nm;
- cars with 8-cylinder engine - 50 Nm.
13. Lower the car on wheels.
Refilling engine oil
Attention! When starting the diesel engine for the first time after changing the oil, please note that the engine will run at idle speed until the engine oil pressure warning light goes out. Only after reaching the nominal oil pressure in the system, you can press the accelerator pedal. If you press the accelerator pedal and thereby increase the load on the engine while the engine oil pressure warning light is on, the turbocharger may be damaged due to insufficient lubrication.
14. Unscrew the oil filler cap and fill with oil.
Attention! When refueling engine oil, it is recommended to fill in approximately 1/2 liter less than the filling volume without fail. Then start the engine and warm it up. Then turn off the engine and after a few minutes check the oil level and add oil if necessary. Excess oil must be removed because it can cause damage to the engine and catalytic seals.
The oil level is correct if it is within the limits indicated by the letter on the dipstick «A». If the level reaches the mark «With», then the oil should be added so that its level is near the mark «A» (see illustration 6.4).
15. Carry out a test drive, and upon completion, check the tightness of the fit of the drain plug and oil filter. Tighten them if necessary, with some care.
16. Check the oil level approximately three minutes after stopping the engine and top up if necessary.
17. Reinstall the engine mudguard.
