I just installed my juice/attitude, before I had no gauges. After my truck warms up, I have 25-20psi. at idle, ....but, If I run down the interstate at 70 mph for a while, then let off the gas to exit, my oil pressure drops to 19-20psi. Could this be bad?

BTW, My truck is a 2000 with 90K mi., and runs perfect . Its been well maintained since new, and doesnt pull a whole lot. It is hot and humid here in Louisiana, and..Im due for an oil change. I run Delo 15w-40.

Thanks

as long as your running Ten PSI at idles hot your doing ok , that is the minumum specs.

Only ten!

Then I guess Im real good. Does anyone concur? It builds lots of pressure as soon as you tap the throttle. Ill be changing the oil tommorow probably.

Should I use delo or rotella? Ive been running rotella in my ford.

dsl kicks gas

i run rotella in every thing, but they say delo is just as good.

na4now:
Is that reading from the dash gauge, or from an auxiliary gauge that is mounted on a gauge pod???? I ask this because the stock in dash gauge is notoriously inacurate. It is however an indication of pressure or no pressure. To clear it up you could do a temporary install of a gauge for test purposes, and possibly stop the worry factor. Just my $.02.

Im reading the gauge on the attitude moniter, on my dash. The dash gauge reads fine. Also,.. when it hasnt been ran for a couple hours, it takes a good 5 sec. to build full pressure.

If I let it warm up in the drive (which I always do atleast for 10 min.), and drive a mile to the store it'll idle at 25-26psi. It only drops to 19-20 when Ive been driving for a while, like on the highway, exit and come to a stop.

And, its only dropping that low when its in gear, idleing. It I out it in park or neutral, the few extra rpm's kick it up to 24-25psi.

So no one thinks 19psi sounds low?

na4now

Can anyone with an oil preesure gauge post, what oil pressure you idle at?

Even if above 10psi, is in spec., this just seems low. I searched here for a whille, and from what Ive red it should be idleing at 25. And it does, ...but just not while its in gear, at a stop.

JohnCA58 is very knowledgeable about these engines - he works with them everyday. Dont know for sure but he may even work for Cummings . I would have confidence in his advice.
