Ok, I have searched but didn't find anything that fit my problem. My stock oil pressure guage in my car is usually between the o,r at idle and at goes up to about the m when driving. On sunday I started the car and oil pressure was fine, but as I started driving and the oil heated up it dropped dramatically idleing almost all the way to between the line and the n and nly going up to between the o,r under load. Well that got me worried so I switched out the stock guage and sender with an electric autometer one and at idle it is only at about 7-10 psi and under throttle it is just under the 25 psi line. My question is what could cause a sudden decrease in oil pressure like that? I was thinking that something may have gotten clog in the pump from when my dizzy gear ate itself (brought it to the shop right after it happened and they completly flushed it out and said it would be fine) but the shop I brought it to seems to think that it is fine and that running a thicker oil would solve my problem (running 5w-30 now) What do you guys think?

could be as simple as trash at the sender as well. I had that happen..there was some thread tape that got sucked into the sender causing messed up readings. I removed, replaced, cleaned out oriface, and it reads perfect now.
I'd check that fitting where the sender screws into for trash first since it's the easiest thing to check. If it was the dizzy or pump I'd think it would either die completely or oil guage would go directly to zero. -
the sender has been replaced with a brand new one from autometer.Comment

try 10W-40, and how old is the filter..and what kind of filter?Comment

ok well, I had the mechanic put on a mechanical guage and it read 40 psi at idle while hot and higher with rpms. The oil is 10-40 and I have a new motocraft filter on it. I just had a bad stock guage and I guess a bad, brand new autometer guage also.
That's 50$ down the drain

you might have a problem with the VR on the gage cluster. There is a high-follutin' name for it, but I am drawing a blank right now.
From my readings here, it usuall effects all the gages, but hey, with trons....you just never know
EDIT I found it. Here is a link to another thread, which also has a pretty good TF link explaining a ICVR
