So I bought me a 2001 camaro z28 with 128k on the clock, oil and filter looked new when I picked it up so I put some miles on her, after 800 miles I noticed It started dropping oil pressure so I went ahead and changed the oil. Oil looked great not metal of any kind and I cut open the oil filter and it looked great aswell, went ahead and filled it up with oil and the pressure came back up to normal, I put a manual gauage on it to make sure it was reading right in the cab and it was within 3psi. Now I have 400 miles on it sence then and the pressure is slowly staring to fall again, any ideas? It's all stock.

What oil pressures (cold & hot) are you getting?

40 psi hot idle and 50-55 down the highway 60+ wot right after the oil change, now im at 30psi hot idle and 45 down the highway. It was down to 20 at idle last time before changing the oil/filter. It seems to drop a certain amount of pressure (in this case 10psi at the moment) every were at ever rpm.

What pressure did the mechanical gauge register (when it was within 3 psi of the other gauge)? Was the mechanical gauge hooked up at the filter?

Its got high mileage, what do you expect? If it was clean drive it and see where it goes.
