Oil is the lifeblood of your vehicle. It protects your GMC vehicle’s engine, lubricating the engine and components, absorbing heat from the combustion area, and suspending and flushing out contaminants that are produced during combustion. When it gets old, and has been in your engine for a long time, it loses its ability to perform. It gets more and more contaminants in it, while losing viscosity. This means it is time for an oil change, a task our team can expertly perform. At Rockville Centre GMC, our Certified Service professionals can perform an oil change and oil filter change, and have your engine back in peak road-worthy condition.
