Triton®FE Diesel Engine Oil

Premium Full Synthetic API FA-4 Diesel Engine Oil; Formulated for Fuel Economy

Phillips 66®Triton FE (Fuel Economy) Diesel Engine Oil is a premium quality, full-synthetic API FA-4 engine oil developed for fuel economy benefits in 2017 and newer engines where FA-4 is specified.

Triton FE is formulated with the highest quality synthetic base stocks and a proprietary low-SAPS additive package to provide outstanding engine protection in diesel engines specifying FA-4. This additive enhancement provides increased engine protection of critical engine parts, despite lower HTHS requirements of FA-4.
