    Default Newbie with oil pressure question for 6.0 vortec

    Hi! New to this forum and have a quick question. looking at buying an 09 crew cab chevy 2500HD 6.0 ohv VVT Vortec. test drove it tonight and really like it but noticed when idling it only has about 25 lbs. of oil pressure and when on the highway, at about 1800 rpm's (55 mph) it only has a little better then 40 lbs. truck has 83,000 miles on it and seems to be well maintained. does this seem to be the norm? are there any other issues i may want to be aware of with this powertrain and truck? thank you in advance for any help you may be able to provide.

    That would be normal for me. About 5-10 better on cold start then settles down to those numbers when warm. 2000 yukon 5.3

    That seems about normal to me as well.

    If at first you don't succeed, chances are, you are using too small of a cheater bar
