Fig. 1.70. Location of the oil dipstick cover
The location of the dipstick for checking the engine oil level is shown in Figure 1.70.
When measuring the oil level, the car should be level. After stopping the engine, wait a couple of minutes to allow the oil to drain into the oil pan.
Then remove the dipstick, wipe it with a clean cloth and reinsert the dipstick until it stops.
Fig. 1.71. Checking the oil level
If the dipstick has a nose (Fig. 1.71), make sure that this nose coincides with the nose of the guide tube. Otherwise, the measurement results will be incorrect - there is a risk of engine failure.
Finally, remove the dipstick again and see what level the oil is at:
A – If the oil level is in zone A, oil should not be added.
B – If the oil level is in zone B, you can add oil. There is enough oil in the engine if its level after topping up is in zone A.
C – If the oil level is in zone C or even lower, oil must be added. It is quite acceptable for the oil level to be in the zone of mark B after topping up.
The oil level must never be higher than zone A.
Under special engine operating conditions, for example, when driving the vehicle for a long time (for 10–12 hours), the oil level should be kept within the A mark, if possible, but not higher.
Topping up engine oil
Fig. 1.72. Oil filler cap
Unscrew the filler cap (Fig. 1.72).
Add a small amount of oil.
Wait a few minutes and check the oil level. Normally, if the oil level is in zone B, do not add more oil, otherwise you may overfill.
The oil level must under no circumstances be higher than zone A.
Otherwise, the oil will enter the engine crankcase ventilation system and be released into the atmosphere with the exhaust gases. On vehicles equipped with a catalytic converter, the oil may burn in the catalytic converter and damage it.
Close the filler cap securely and insert the dipstick all the way in. Otherwise, oil may be ejected when the engine is running.
