Cm871 oil pressure loss
2010 Lonestar cm871. Just over 200,000 miles. New DPF and engine oil installed by dealer before I purchased truck less than 500 miles ago. At startup, engine oil is at 40 PSI. Within 15 minutes of driving goes down to 20 psi. Attach an empty trailer, drive 20 minutes oil pressure drops to 10 psi with stop engine alarm. Coolant stays at 180°oil temperature at 220°.Hooked up mechanical oil pressure gauge that verifies OEM gauge is accurate. Any truth to fleetguard [/size]oil filters plugging up?
