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, do not neglect any detail to avoid falling into large errors such as the following.
Oil change: common mistakes
In what aspects should you pay more attention when changing the oil of your vehicle? What are the mistakes that can be made due to absentmindedness or bad 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 increased 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 it is not capable of filtering remains in the crankcase, and can be sucked in by the oil pump. Filter clogging can also cause oil pressure to rise.
Incorrect tightening of the crankcase screw
Always tighten the crankcase bolt with the torque indicated by the manufacturer. If the torque is lower, it will most likely lead to oil loss problems. On the contrary, 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 their manuals about the amount of oil that each model should carry. In any case, a level check should always be carried out since, on occasions, not all the oil has been properly drained and, when new lubricant is introduced, 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 proceed with its replacement
To change the oil and check its level, the engine must be at service temperature. Once this temperature has been reached, the engine is stopped and a few moments are waited for the oil to return to the crankcase. Once all of this is done, the replacement process can begin. It should be noted that the car must be on a flat and stable surface.
The last mistake you cannot make is to trust yourself, because it is a routine task or because you think that you already know what each vehicle needs without consulting the manufacturer. Whenever you' re sure of something, check it one last time. It is the best way to avoid unexpected problems.
