Something is going on with my oil pressure. The guage is reading 10psi at idle and when I am just driving normal it's anywhere between 19 and 23. Before is would be around 35 psi driving and about 29 to 30 idle. I'm not quite sure what the deal is. It's odd. But if anyone can help me let me know. Thanks

If it happened suddenly its probably just the oil pressure sender. If its not the sender, it's more serious.
