Cherokee oil pressure?
I have a cherokee 96 4.0. The oil pressure seems to be a bit off? It's a
auto.
When started cold the gauge reads around 60 psi. Then once warms seems
to drop down to around 40.
Is this norm. My wrangler never did this. Difference for automatic. ? or
problem with the gauge? It does seem to drive a bit differnt warm...
140,000 miles.
Any ideas would be great...

Re: Cherokee oil pressure?
Wow, that sounds like you actually have a working sender and gauge!
Most likely the one in the Wrangler was crap.

Re: Cherokee oil pressure?
Somewhere I read that 10 psi per 1k rpm's is ok. So anything under 4000
rpm's at 40 psi should be fine. Also with that many miles in the summer
months you may want a thicker oil if it's real hot in your area..
