Hi all,

Trying to decide about keeping my older Chevy p/u or buying a newer used one. One thing I noted - on my oldie, '99 with 5.7 L, oil pressure at moving RPMs, warmed up, indicates just abouve 1/2 scale, 45-50 psi (no idea how accurate the gauges are...) and at idle, it drops to just above 1/4 scale. Seems to me it used to run a little higher at speed and did not drop nearly so much at idle.

So, I happend to test drive a newer Chevy with the 6.0L and noted very similar behavior. That kinda surprised me, and tenatively put me off on that particular truck. But, maybe my recall is incorrect, and this behavior is normal.

Anyone have one of these rigs - either engine - that can advise? Are those indicated pressures normal or are both engines showing signs of wear? Just collecting my thoughts.

Thanks much, regards,

Marty
