whats good oil pressure wrangler 4lt
 

Wahts a good oil pressure for a 4lt wrangler............

mine sites at 3 ....driving just a bit above

but sometimes when idle drops below 3 ....2ish

is this normal as i dont remember it doing this before

Re: whats good oil pressure wrangler 4lt
 

Oil pressure will always vary up and down directly in step with the
engine rpms. The faster the engine is turning, the higher the oil
pressure and visa-versa. "2ish" is actually around 20 psi and is fine
at lower rpms. I use the 10 psi for every 1K of engine rpms as a rough
guideline as what is normal.

Hi Mick,
You could probably drive another hundred thousand miles, but it's
tired. Idling it's designed to maintain forty pounds, as that is the
bypass pressure assured at the pump:

I believe the gauges from any new car manufacturer to be
inaccurate, but they're going to be in the ball park, satisfying most of
us. If you value your machine like most Hot Rodders, than supplement
them with Real gauges from http://www.stewartwarner.com/ or
http://www.autometer.com/

the spec is 10 psi or higher at a hot idle

FWIW I get ~ 50 psi at 2K when fully warm on a 33k miles engine (Mobil 1
changed every 3-3.5 k miles)

Which engine? The I6 (4.0) is "supposed" to run between 15psi and
40psi. Of course those damn gauges were NEVER terribly accurate. My
Cherokee sits at about 38 at idle and about 45 at cruise.

Re: whats good oil pressure wrangler 4lt
 

Its the I6. Some cretin at Jeep decided to measure it in bar - it runs about
3.25 bar at 2K rpm.
At idle it is about the same as yours.
