Oil Pressure question Problem/ Need Help
My Oil Pressure gauge on my dash never gets much higher then 40 and only rises when i turn my car on after it has sit for a while and will only rise when i accelerate and will stay at around 40 when I'm driving with my foot on the gas. When i let off the gas the oil pressure gauge drops, when I'm at a red light idling it drops towards the red area the warmer the engine gets (180 -200 area) the closer it gets towards the red zone on the oil pressure gauge about a needles width away from red. My drive to work is roughly 25-30 minutes my temp gauge has gotten a fraction of the needles width over 200. Need help unsure of what is wrong. Is it the oil pump, oil pressure sending unit thing.

Just performed an Oil change over the weekend, super tech 10W30 super tech filter, 98,000 miles on car. Now before anyone rips into me for using wal-mart brand let me share some business truths, this oil and filter are not manufactured or produced by wal-mart, it is bought by an oil company most likely penzzoil and the filter is by Fram and all wal-mart does is print their name on it. Now from what i hear Fram does not make good oil filters how true this is i do not know.

Very true... The Fram orange oil filters are garbage.... I don't think there is another filter out there thats as bad as the Orange fram oil filters...
The oil I am not so worried about tho.. If that Supertech oil filter is made by Fram just painted blue... I'd be concerned...
we steer very clear of Fram Oil filters...
I use AC Delco PF47 or PF52 as well as Puralator, havoline( Puralator actually makes this one) or Wix..
If you have a Fram filter that could be part of the issue... Its possible to have a bad sending unit as well.. At 161k My motor is starting to take a Wrist Pin dump... But the oil pressure ranges from 30 Psi hot at idle to 50-60psi at roadspeed... And the oil has 4700-5000 miles on it...( Mobil 1 )

so your thinking i should try a new oil filter puralator and if nothing happens then suspect sending unit is there anyway to test if thats bad before i change my filter. for example take it off and test with volt meter? side note if i don't drain the oil pan and take off the oil filter will the oil in the crankcase all drain out or will what comes out when i do a normal oil change come out of the oil filter area.

whats a wrist pin dump? trying to learn sorry about the questions. My guess is that it is the pin that connects the connecting rod to the crankshaft but I'm not sure and as for the dump i imagine some sort of verb describing wear perhaps

You can change your filter, but you'll most likely have to add 3/4 to 1 quart depending on how much comes out...
Its hard to say if the filter is the issue of the sending unit... The best way to know is to check it with a Oil pressure gage( mechanical ) and if its close to what the dash gage was reading then you may want to try another filter... we have seen instances where the Filter was the cause... And in some cases the dash gage was off.. Its really hard to say...
I get 70 Psi cold start.. On the interstate I am always at 50-60 Psi all day long
