Changing your vehicle’s engine oil sounds straightforward enough. You can either replace it professionally at the local garage or DIY the entire task at home. Nevertheless, it is a necessary step that should not be skipped to improve engine performance and efficiency. Timely engine maintenance will save you thousands of dollars in repair ahead. So, if you decide to change the engine oil at home, avoid making these common mistakes. Using the wrong type of oil Not all vehicle engines run on the same oil type for lubrication. It varies depending on the type of car and driving conditions. You can either use conventional motor oil, the cheapest of all variants or switch to a synthetic blend that provides better viscosity and resistance to drastic oxidation caused by changing weather conditions. Alternatively, consider using high-mileage oils that are both pocket and environment-friendly. Not checking the proper oil levels You need to fill in the right amount of oil that needs to be used for optimal engine function. Overfilling the engine causes the lubricating oil to leak inside the gaskets and stall the engine. And using very little oil increases friction and causes premature wear of the components that make up the engine.
