Motor oil and car engine technology has advanced so much over the years that, depending on the recommendations of your vehicle’s manufacturers, it may no longer be necessary to get an oil change every 3,000 miles – the average oil change interval is around 7,800 miles for today’s cars. This is great news because it means less time and money spent taking your vehicle for an oil change. However, this does not mean that oil changes can be skipped. Your vehicle’s engine needs motor oil to operate properly and without it, the engine seizes up and dies. In order for motor oil to keep your engine running, it can’t be too old. Case in point: if motor oil is left in an engine for too long, the oil begins to break down, which can lead to nasty deposits of sludge in your engine. Instead of lubricating and cooling the engine parts, the oil sludge can damage the parts, which is something you want to avoid at all costs. Getting regular oil changes will help to ensure a long engine life.
