Hello my car is 1995 v6 3.4l it the oil pressure starts at about 40psi then driving drops to 20 to 25 psi but then gauge just keeps bouncing i have a z28 gauge cluster cause the stock one went out im wonderin if i should just put mechnical gauge in with a t bar so i can u stock on and mechanical well let me kno thanx guys

 

just remove the factory sensor and get an after market oil pressure gauge, it wont hurt a thing. I've been running my 95 that way for quite a while now. You'll be happy with the more accurate reading.
