The German Technical Inspection Service (TÜV) has warned against driving a vehicle if the engine oil has been inadvertently filled in excess; This may cause serious engine damage.
The authority attributed this risk to the fact that an increase in the level of engine oil than the required amount may result in foam, which negatively affects the efficiency of the oil in reducing the friction process between the engine parts, which in the worst cases may lead to severe damage to the engine.
In the event that the maximum oil level is slightly exceeded, the car may be taken to the nearest maintenance center to get rid of the excess amount of engine oil, but in case of doubt about the amount of excess, the authority advises not to move the car and request a mobile maintenance service.
The German authority indicated that the damage caused by increasing the level of engine oil exceeds the damage caused by its severely low level, and therefore when refilling the engine oil should not rely on inaccurate traditional methods such as measuring the required amount of oil with the wrist or just looking.
The correct gauge is determined by the dipstick in the oil sump using the MIN and MAX markings. The authority advises reviewing the car’s user manual, which includes information on changing the engine oil and its quantity, and the exact amount of oil between the two marks is often estimated at one liter.
Alternatively, the oil can be added in batches of 100 milliliters at a time and the oil level checked repeatedly with the dipstick until the oil reaches the desired level marked MAX.
In order for the engine oil measurement process to be carried out correctly, the authority advises warming up the engine, then stopping it and leaving it for ten minutes before conducting the oil level measurement process. the oil.
