– Engine oil protects the engine’s moving internal parts against wear. It also creates a protective seal between moving and stationary parts while helping to cool the engine. As engine oil deteriorates, it loses its ability to properly protect the engine. When you come in for an oil change, we perform a complimentary light check, adjust tire pressures, inspect items like air filters, hoses, and belts, inform you of possible fluid leaks, top up your fluids and perform a battery test – it’s not just an oil change
