Oil pressure issue
2002 ISX-oil pressure gauge fluctuates, up & down,
Engine never shuts down. Runs great no power loss. Oils only 2 weeks old., Thinking oil breakdown or filter problem. Maybe Sensor problem. Am I on the correct path?

could be a oil pump going bad, could be a semi-blocked pick up screen. you do not mention the miles on the engine.

If it started doing that since the oil change, I'd look at the oil and make sure they used the correct weight and filters. If the pressure was fine for say the first week then started going wonky I'd suspect a sensor, either way I too would have the pressure checked and verified with a mechanical gauge.
You also didn't mention how much it fluctuates, some is normal.
