Engine Mechanical problem
2001 Isuzu Trooper 6 cyl Two Wheel Drive Automatic 63000 miles
I just purchased a 2001 Isuzu trooper. My question is, what is the oil pressure suppost to be? When cold it is at 85 psi, driving and at idle. Than when it's warm it drops down to about 40 psi while driving and 10 psi at idle. Is this normal? I put synthic 10w 30. What oil should I use?
have the same problem?
