An oil change is an essential part of vehicle maintenance. You can either get it done at the garage for a premium or change the oil yourself with the right set of tools. Although the process seems straightforward, there is room for errors here that can affect vehicle performance. From missing key steps to using the wrong type of oil, here are a few common oil change mistakes to avoid: Overfilling or underfilling the engine You should pay attention to the oil levels and the recommended amount of oil the engine needs. If you fill it up to the brim, the fluid will leak into the gaskets and pistons, stalling the engine. If you add too little oil, excessive friction will damage the engine. You need to add just the right amount as per the user manual. Choosing the wrong type of oil The right oil type can vary depending on the type of vehicle and the driving conditions. Premium synthetic motor oil is built to survive weather changes due to its high viscosity and resistance to oxidation. Some owners may prefer high-mileage oils that improve engine performance and boost mileage. Generic or conventional motor oils, the cheapest option, are ideal for simple engine designs and regular driving conditions.
