Detroit Diesel Corporationsays it is moving its factory-fill engine oil to low viscosity FA-4 on the DD13, DD15 and DD16 heavy-duty line of engines.
Detroit Engineering has issued two new fluid specifications for the use of the recently introduced PC-11 category: DFS 93K222 covers CK-4 engine oils, which replace CJ-4 as the industry standard. DFS 93K223 covers the FA-4 engine oils with an emphasis on fuel-economy improvements.
Affected tractors are equipped with an automated Eaton UltraShift Plus or Eaton Advantage Transmission with right hand stalk shifter. In the affected trucks, the display on the instrument panel can indicate “N” when the shifter is set into “D” or “R,” causing the truck not to move.
The new “health-based requirements” will need to be met before a driver is allowed to register his or her truck through the Department of Motor Vehicles, CARB says. For older vehicles, CARB says they must be either replaced with a 2011 or newer vehicle or repowered with a 2010 or newer engine.
