1. The oil level should be checked when the oil temperature is 60°C. This temperature after a cold start is reached by driving for about 10 minutes. After turning off the engine, wait five minutes for all the oil to drain into the oil pan. Park the car on a level surface.
2. Pull out the dipstick. If the engine is warm, be careful because the adjacent parts are very hot. Wipe the dipstick with a clean, frayed cloth or paper towel. Then insert the dipstick again until it stops in the guide tube or hole 8 in the cylinder block, wait a little and pull it out again.
3. Read the oil level. By the way, dark oil color does not necessarily mean that the oil needs to be changed. When using branded motor oils, this color appears even after a short mileage due to the fact that dirt particles accumulate in the oil.
4. The amount of oil that corresponds to the distance between marks 1 and 2 is 1.0 l. If the oil level is not below the minimum (lower) mark, then it is enough to add half a liter of oil. Never add too much oil! Excess oil must be sucked out. Under some circumstances, oil is sucked in through the crankcase ventilation system and contaminates the air filter. In the case of too much oil, engine seals and even the catalytic converter may be damaged if oil gets through the combustion chamber into the exhaust system.
5. Use a clean funnel to add oil.
Arrow 1 shows the maximum mark, arrow 2 shows the minimum mark, a is the area between the rasterized field and the maximum mark: do not add oil! b is the oil level in the rasterized field: you can add oil, c is the area between the minimum mark and the rasterized field: add no more than 0.5 l of oil! It is enough that after adding oil the level is in area b.
To check the oil level, wipe the dipstick with a clean, lint-free cloth or paper towel. Be careful when checking on the road, as the engine gets very hot!
