Oil pressure
Not sure if I'm posting the right place but here's my question I was towing a trailer with my 98 xj and when I was sitting at Idol my oil pressure would drop to 0 but under normal driving it was at 30 what does this mean. Please help.

Make sure oil is reaching the top of your engine at idle, you can take a peak under the oil filler cap.
Verify these readings with a mechanical gauge. The oil pressure sending units on XJs are notoriously prone to failure.
That said, the oil pressure specs are: 13psi and above at hot idle and 37-75psi when above 1600 RPMs.

Sounds like old age. Is it knocking? When the gage is reading zero look under the oil fill cap and see if any oil is flowing...if so I wouldn't worry too much unless your willing to rebuild. How many miles? Change oil & filter. What kinda climate do you live in? What was your engine temperature when towing? What was your idle speed? We need data to analyze.
