Hi all, I'm new here and to the falcon, I recently bought a 1996 EF XR6, that's been standing for a year or two.

Im currently having issues with my oil pressure that keeps on dropping when driving.
I have to switch off the car and start again just to drive few meters before light comes up again, checked car no oil or water leaks... no funny tappet noise when light goes on. Oil and water level normal

I do know previously the 1st and 2nd time it happened my water pipe from the radiator to thermostat housing blew... unsure if its related, but bought a new thermostat that ill be fitting over the weekend.

I've changed oil from 15w40 to 20w40, but read along the forums saying 20w50/high mileage 25w60 oil can keep the oil pressure?

Has anyone ever experienced this? and which oil grade will work 20w50 or 25w60? it has about 321000 km on the clock.

I have an EL XR6 with the Hybrid motor, which means it has the AU head. I have owned it for over six years now and right from the get go I have had the same problem. The only difference is that my EL only loses oil pressure on hot days. The rest of the time the pressure is lower than I'd like but okay.
I think that I saw a slight improvement after changing the oil pressure sender.
I hope that that helps...

Thanks hudsonhawk69, Ill def check at the oil pressure switch over the weekend.
Only downfall is if it is the switch Ill either have to get used as I'm in cape town and no one here sells new parts for the xr6. I only saw a 0.3 bar oil pressure that is universal. Still need to check how the barra engine sender is compared to this engine's switch

Timely resolution of oil pressure problems is critical to the health and longevity of your engine. Don't hesitate to consult a trusted mechanic for a proper diagnosis and repair plan. slope
