Common Mistakes When Changing Oil in a Car Yourself

Model: (Various brands) Various
Part: Warning light – error code

Video tutorial

Here are the most common mistakes when changing oil yourself: the first is, of course, not doing it in a timely manner, but delaying it, whereas it is advisable to do it more often than the manufacturer recommends, especially if used in harsh weather conditions or heavy urban traffic.

Another common mistake is using oil with incorrect specifications or viscosity compared to those indicated in the vehicle's user and maintenance manual, which is the reference we should follow.

Another mistake is over-tightening the drain plug and oil filter; these can cause leaks and seriously damage the engine, so use a torque wrench if possible. Remember to change the gasket and plug with every oil change.

Often, the oil is drained when the engine is cold, so the oil does not come out completely; the engine should be slightly warm to increase oil fluidity. During the filling phase, we can also make mistakes by overfilling or underfilling the engine: follow the instructions in the user and maintenance manual.
