As of recent, my oil pressure has been around 80 psi. Up until about 3 weeks ago it usually stuck around 45 psi. Is this normal? I did an oil change about 100 miles ago, and this hasn't fixed it. I was a bit late with the oil change (4,000 miles), but I didnt think it would be of too much harm since I use a synthetic motor oil. Not sure whats up.

Also, I had the hardest time changing my oil. For some odd reason, my oil filter wouldn't budge for anything. I only use a filter wrench to quarter turn it, so I dont think thats what it was. I ended up spiking a punch through the filter just to turn it out. (MESSY)


Anyway, what do you guys think is my problem?

The oil PSI gauge in these cars is a dummy gauge more than anything. Mine goes all over the place all day.

You can easily go more than 4,000 miles on synthetic. I usually go 6,000.

Did you do your last oil change? I notice that when shops do mine the oil filter is on there with some form of super glue. Hahaha.

Yeah I always do my own oil change. If we havnt already taken out the steel trash bin, I'll try and find that filter and put up a picture. I pretty much had to destroy that thing to get it off!

Don't use a wrench, period. 3/4 turn past when the gasket kisses the flange. Any tighter, and it's glued on.

Replace your pressure sender with an AC Delco one. 99% likely culprit.

^^ This for sure.

My factory unit failed not long after I bought the car, was reading max pressure.

Replaced with an O'Reilly unit, lasted 2 years. The pressure was reading fine, but it was leaking oil through the unit. Bought an AC Delco switch/sender from work to replace it with. Failed in three days (reading max), so I swapped it out under warranty of course. Now I'm good to go.
