Hello everyone,(4.3 v6 96k miles, and oil change done 3 weeks ago) heading to work today noticed my oil pressure around this range. Is it ok to be that low instead of being in the middle, any suggestions or gauge just being stupid. Or is it normal?(This was after a 30 minute drive all warmes up)

I was having the same issue with my Blazer and my Sonoma. I decided to delete the oil cooler. Now my oil pressure is better than ever. My blazer the oil pressure at idle after it's warmed up is 42 PSI and on the freeway it runs about 64 PSI. My Sonoma is just a little lower than that. It's about 39 at idle in about 56 on the freeway, but my Sonoma has 480,000 on it. Both of them are 4.3 l.

I whole heartly agree with Salty. Just over 20 psi at idle is fine. If it's over 40 psi at 2K on the highway, all is good.
