Phillips 66 Lubricants announced that it has extended its product quality guarantee to protect heavy-duty fleets against lubricant-related failure in the engine when using Guardol FE 10W-30.
With more than 92 million miles of field testing on Guardol FE 10W-30, Phillips 66 says that it has proven the FA-4 product, like CK-4 oils, offers excellent wear protection benefits, but with the added benefit of increased fuel efficiency.
The warranty means that Phillips 66 will pay for parts and labor deemed necessary to repair damage to engines if the damage was caused by lubricant-related failure.
The warranty will require that:
- Engines are used under normal over-the-road operating conditions and serviced with Phillips 66 Guardol FE 10W-30 (API FA-4)
- Lubricants are changed as specified by the engine or equipment manufacturer maintenance schedule
- Written documentation or maintenance records are provided that show the engine or equipment was serviced and maintained at regular intervals as specified by the manufacturer
- The proper lubricant level has been maintained in the engine or equipment through documentation of frequency of oil make-up
The Guardol FE product is warranted for use in 2010 and newer Detroit Diesel engines and 2014 and newer Cummins, PACCAR, Navistar, Volvo/Mack engines.
