Some company.. ptotech????? did a half hour TV paid advertisement to advertise their oil additive. They drove the cars 100s of miles in LA summer heat with no oil. Apparently you can do that with any old car as long as the cooling system is working.
Chris, we all think catastrophe when oil pressure drops. Me, I would shut the engine off. But if you had to keep going, medical, war, life... just know an engine will run for hours without oil.Serious? That's pretty unbelievable, but I'll believe it if you say it happened!
I'm not sure how the hell that's even possible though!?
That claim about running the engine without oil was done by Prolong, I remember it well. It was a scam. Start reading about half way down at point #3 at www.autoblog.com/2010/11/05/automotive-alchemy/
The CU test showed two identical engines, one after the Prolong additive and one without it, both failed in 13 minutes after 5 miles after they drained the oil.
It means you're running a newer TJ where the gauge isn't showing the true oil pressure, it's just showing a mid-scale reading to prevent people from panicking when the see the oil pressure varying up & down as it does in reality. In reality, your engine is probably running 20 psi or thereabouts. 10 psi per thousand engine rpms is rule-of-thumb for acceptable oil pressure.What's it mean if you have 65 pounds of oil pressure and you're running like 1800rpm?
Which Jeep? It should drop for the 2002 but it should not for the '04. 65 psi at 1800 rpms would be a little high for the '02, what viscosity of oil are you running?Even though it drops when I put it in neutral?

When my oil pressure sensor went out it was showing 75-80 psi. So it should be working unless it broke in the last 5k milesAt minimum I would run a cluster diagnostic to confirm the gauge is operable. If you have not run the diagnostic before just hold the trip meter reset button down and turn the key to the run position (not start). All your gauges will then actuate thru their ranges if they are operating correctly.
