Motor craft SAE 5W-20 Full Synthetic Motor Oil is manufactured with high-viscosity index, premium-quality, synthetic base oils that provide good high temperature and low temperature performance. It helps minimize engine deposits and wear, protect against high-temperature oxidation and turbocharger deposits, low-temperature gelling, rust corrosion and foaming. The friction-reducing technology in this motor oil provides superior wear protection and energy-conserving characteristics, which result in significant improvement in fuel economy when compared to SAE 5W-30 and 10W-30 motor oils.
