Just picked up a 2001 Dodge Dakota with the 3.9 V6 in it. I have had it for
a month no problems at all.But tonight i noticed when i stop for a light the
oil pressure needle dips down to the first normal range line,then when i am
moving it goes up to the middle of the guage.Its not in the red area,its in
the safe area, is this normal? I seem to remember most of my cars it stays
in the middle, but it would be logical for pressure to drop as the engine
speed drops, plus i have never owned a dodge before.
As already stated this is normal. Your other cars had what is commonly
called an "idiot guage". That is when the car maker has so little
faith in the buyer the guage will always show normal unless pressure
(temp etc.) is way out of whack. Since you are not the original owner
I would still say put in a mechanical guage that shows exact pressure
and compare this to the service specs.
Yep, Ford has not used a true mechanical gauge in their truck line and auto
line for over 20 years they use idiot gauges. Chevy has done this off and
on for years including some Chrysler products mainly their car line. A
lot of foreign manufactures are trending this way too except for high end
vehicles. The main reason is cost, the idiot gauges are half the cost as a
true sensing gauge. The idiot gauges just need a pressure switch closes the
contact and magic the vehicle gauge reads a voltage signal. I agree if you
really want to see what is going on regardless of manufacturer gauges
install a good set of mechanical gauges.
I am glad to hear all this.I'm not much of a mechanic but when you think
about it,it makes total sense for the guage to go up and down as pressure
increases and decreases with engine speed.
I do have a ford ranger 2002 as well,the guage is always in the middle.
