I have access to Mitchel and they say if my oil pressure is between 55 and 85 LBS @ 3000 rpm hot is ok. @ 3000rpm the oil pressure is 40 PSI and can go as low as 10PSI @ at Idle. It just not seem right. I have check Isuzu Tech info and they have no info on Low oil pressure for any engine or year? Is there any info on this? I was going to donate $5.00 us but I am a little leery about giving my Visa out but will mail a $5. if you give a good answer and address. Dave Wittman Our E-Mail is genwitty@comcast.net
