Keeping the engine healthy with the proper amount of clean oil is vital to a well-functioning engine. But what happens if you forget? Well, it depends how many miles over you let things go. Clean oil protects the engine's many moving parts, creating a barrier between metal pieces that rub together at high speeds in a heated environment. It also collects contaminates created by the combustion process, moving them to the oil filter that traps sludge until it can be disposed of. Eventually, the extreme environment in the engine will start to break down the oil, causing it to lose its lubricating characteristics. When this happens, the compromised oil will damage the engine, since friction can take over and promote overheating.This heavy-duty job makes oil vulnerable to breakdown with time, which is why manufacturers recommend having the oil repla ... read more

With various motor oils to choose from (and different opinions to sift through), how can you know which one will work best with your vehicle? Fortunately, the process of finding a great fit doesn't have to be overwhelming, and it mostly depends on factors like driving habits, vehicle style, and climate.
