So after my first DIY oil change I am still getting weird oil readings.

Car is 1999 C2 Coupe 6-speed with about 9k on engine

Today I did some more testing....

1. Startup - no oil pressure for 1 second then up to 5 if cold

2. hot idle. 1.65 when warmed up at idle

3. level 4 at 3k rpm when hot

4. Hard accel. 1st gear fine.....2nd gear when comming throuhg 4500rpm it starts to dip. dips down to 2.75-3.25 before holding around 4

5. Sweepers: on both left and right sweepers 3rd gear 3k rpm......dips to 2.5 and bounces (very erratic needle)

I have read about oil starvation in other threads but I have not found any info like mine above. Is this normal?

TIA

Ben

Ok....never noticed such huge swings before.

Makes me worried about drivng her hard in corners

On startup mine goes right to over 5 bars, then when warm a little over 2 bars at idle, 3K little over 4 bars. No dips on hard acceleration.

Currently 30K on the car.

My 2002 C2 does exactly the same thing on all points (40k miles) I noticed that if you apply the gas or brake (upset the balance of the car) when exiting or entering on a wide sweeper ramp, the pressure needle dances. If you keep it smooth it stays steady. In fact, when the oil is really hot, (like over an hour) I noticed a fluctuation eveytime I hit a dip on the interstate. It's THAT sensitive. This is why on most cars the oil pressure indication is heavily damped, so you don't see spikes & dips like that. Sounds all normal to me.
