    I know in a n14 that rotella works great. My dump truck had 495,000 miles when i sold it i usually left it one gallon low to add a gallon of lucas. There are a lot of great additives on the market today. The engine had close to 4000 hours on it. Still ran good.
    Dump trucks that haul asphalt idle sometimes 12 or more hours a day. Lucas and rotella 20w50 worked for me. Changed injectors one time, no engine repair , during it 17 years with me

    Sorry should have specified that the V6 engines have hydraulic lifters.
