Easiest to just live with the light,
learn to put into neutral at lights
and all is fine. The oil pressure
switches have different values too,
some will stay off until 5psi and
others will make contact at 15psi.

EDIT for quick afterthought: for the
time being you can live with the
light. Many never do anything to
change it, when weather cools down
it stops on its' own anyway.

I am using 10w-30 in my 67 110 Monza with PG. With my Custom Instrument Panel (Dakota Digital) I can 'see' my actual oil pressure. In hot weather it will drop to 7 psi when stopped at alight.

I also have a Corvair OP switch installed (5 psi) that will turn on the Check Engine light on my Custom panel. With my current settings the Odometer reading changes to Oil Pressure when it drops below 10 psi.

Even though the pressure drops when I am stopped the Pressure Switch never turns on the light The pressure comes up to about 20 psi when driving and the engine seems happy.

That is why I think you may have the wrong Oil Pressure switch installed.

JMHO!!

I've always been told that GM engines with Hydraulic lifters get the 7 psi, solids 5 psi.

As I said above there is a range
of where the switches read the low
pressure. No two are exactly the same.

Rock Auto would not be my choice.
Try NAPA who deals in Niehoff or
find Standard Ignition Blue
Streak. Even name brands have
a pressure range.

Rock Auto sells the same brands everyone else does. I've even bought Napa branded parts from them.

Low rpm? What’s your rpm when you stop ( car in drive)? Did this issue suddenly happen or you changed/fixed something and then you start seeing...?
Are you using Pertronix ignition II?

Steve sez: ign system is irrelevant to
the temp/press light problem. IF you
were having poor idle or missing at
idle speed THEN the electronic ign may
be at fault.

You have a fairly common problem of the
combination of very slow idle speed due
to being in gear at idle speed PLUS
'maybe' hot engine which increases the
clearances inside PLUS 'maybe too much
clearance in your oil pump PLUS 'maybe'
too thin of oil. As I have already
stated, the issue is not uncommon with
PG owners. Put trans selector in N at
lights and the temp/press warning will
disappear.

Regardless of your issue make sure DO NOT USE Ignition II
