GUARDOL FE® SYNTHETIC BLEND DIESEL ENGINE OIL

PREMIUM SYNTHETIC BLEND API FA-4 DIESEL ENGINE OIL; FORMULATED FOR FUEL ECONOMY

Phillips 66® Guardol FE (Fuel Economy) Synthetic Blend Diesel Engine Oil is a premium quality, part-synthetic API FA-4 engine oil developed for fuel economy benefits in 2014 and newer engines.

Guardol FE with Liquid Titanium is formulated with a blend of synthetic and high-quality Group II base stocks and a proprietary low-SAPS additive package to provide outstanding engine protection in late model diesel engines. It is fortified with our exclusive Liquid Titanium protection additive for enhanced oxidation resistance and protection against wear. This additive enhancement provides increased engine protection from a strongly bonded titanium shield formed on the surface of critical engine parts, despite lower HTHS requirements of FA-4.
