Oil is essential for maximizing the life and performance of your engine. It cools parts, thus minimizing energy loss and engine damage. It also fights rust and corrosion while acting as a sealing space between piston and cylinder. In addition, the additives in the oil remove impurities, sludge and existing deposits, and prevent damage.
Current engines, especially those equipped with turbochargers, are extremely complex and require lubricants of precise viscosity containing specific additives and detergents which deteriorate over time. If the oil is not changed regularly, a gelatinous sludge can build up and damage the seals and your engine.
A complete oil change includes the installation of a quality filter that retains its ability to filter dirt and particles over the miles to keep the oil performing.
