Shell Helix Ultra 5W-40 maximizes performance right up to the next oil change Shell Helix Ultra has been formulated with Shell’s ultimate active cleansing technology. It works harder to protect than conventional motor oils by continuously helping to prevent dirt and sludge build-up, for better responsiveness and improved performance, thus helping your engine to operate at its full potential right up to the next oil change.

Shell’s ultimate active cleansing technology allows up to five times more effective at removing sludge from dirty engines than a mineral oil. Long-term oxidation stability lets up to 30% more protection than other fully synthetic leading brands tested. Low viscosity, rapid oil flow,andlow frictionenablegreater fuel efficiency and easier cold starting. High shear stability maintains viscosity and stays in SAE Grade throughout the oil change interval. Specially selected synthetic base oils reduce oil volatility and therefore oil consumption and the need for thetop-up
