Oil is the lifeblood of your car’s engine. It keeps all of its parts moving smoothly, absorbs excess heat, and contains additives that help clean up nasty, harmful chemicals. After spending thousands of kilometers keeping your engine running right, your used oil degrades leaving harmful deposits, and over time can form sludge, which decreases your engine’s performance and lifespan. Regular oil changes keep your engine running smoothly by assisting in cooling, lubricating, cleaning an engine’s moving parts, and improving gas consumption to extend the life of your engine.
