Welp I had great luck with conventional oil 10W-40 but when I switched over to full synthetic I noticed my oil pressure was a bit low it's sitting right at 10-13 PSI when idling but it also idles at like 600-700 when hot even with new Bosch 784 Injectors and spark plugs. Everything seems functional I know the head isn't cracked I am just wondering if anyone else gets oil pressure like this on their rigs when it is hot outside.

When I a cruising down the highway at 2K rpms it's sitting right at 45 PSI and on start up when the oil is cold it's at about 60 PSI

seems normal enough to me just wondering on other peoples thoughts

 

What brand and viscosity of synthetic oil did you switch to?

 

[QUOTE=IJM;3242763]What brand and viscosity of synthetic oil did you switch to?[/QUOTE

Mobil 1 full synthetic
10-40

 

What oil filter are you running?

 

Napa gold

 

At one point my oil pressure started fluctuating after I started using Mobil 1 synthetic..

I was using Mobil and K&N oil filters..

As soon as I swapped to Mopar oil filters the oil pressure stabilized.

I'm now running Mobil 10w40 High Mileage.. my oil pressure runs between 35 and 70 on the gauge..

.

 

I might do that I'll clean the oil pressure sending unit but I seem to be in a healthy zone for idling at 700 in the heat with a pressure of 10-13 steady

 

I would check it with a good mechanical gauge.
