The correct lubrication of the car is basic for the maintenance of the car and begins with the oil change in the periods recommended by the manufacturer. This task is easy for a professional. However, you should not neglect any detail to avoid falling into bulk errors such as the following.
Oil change: frequent mistakes
In what aspects should you pay more attention when changing a vehicle’s oil? What are the mistakes that you can fall into due to mistakes or poor decisions?
Using the wrong oil
Always use the oil indicated by the manufacturer for that type of engine. It is necessary to know if it is synthetic or mineral, monograde or multigrade … Putting the wrong oil in the engine can cause an increase in fuel consumption, abnormal noises, seal breakage and, in general, very important internal damage.
Do not replace the filter
The oil filter must be replaced every time the oil is changed. Otherwise, all the dirt that is not able to filter remains in the crankcase, and can be sucked in by the oil pump. Clogging the filter can also lead to an increase in oil pressure.
Incorrect tightening of the crankcase screw
The crankcase screw must always be tightened to the torque indicated by the manufacturer. If the tightening torque is less, it will most likely lead to oil loss problems . Conversely, if the tightening torque is excessive, it may be difficult to remove the cap the next time .
Excessive or insufficient oil level
Each manufacturer informs in its manuals about the amount of oil that each model must carry. In any case, a level check should always be carried out , since sometimes all the oil has not been properly evacuated and, when introducing the new lubricant, an excess oil is caused in the system. To avoid this, add the oil little by little and check the filling through the dipstick.
Incorrect oil temperature to replace it
To change the oil and check its level, the engine must be at operating temperature. Once this temperature is reached, the engine stops and waits a few moments for the oil to return to the crankcase. Once all this is done, the replacement process can begin. It should be noted that the car must be on a flat and stable surface.
It is important to know how to choose the best procedure for each car . For example, in some cases, the manufacturer does not allow oil aspirates to be made on its models. In the case of using this system, a flexible probe with the maximum possible diameter should be used and inserted without exerting too much force. Otherwise, the tip may drift to the bottom of the crankcase and a large amount of used oil may remain in the engine. In any case, the removal of engine oil through the crankcase is the most recommended system to obtain the best drain.
The last mistake you cannot make is to trust yourself, because it is a routine task or because you think you already know what each vehicle needs without consulting the manufacturer. Whenever you are sure of something, check it one last time. It is the best way to avoid unexpected problems.
