Low oil pressure

[UPJOHN]

My oil pressure gauge was reading low at idle, so low the check gauges light was coming on.
Last winter my grandson bought a used snowmobile that after a few miles the check engine light would come on. Reading on the internet, the fix was to apply dielectric grease to the fuel injector connectors. Problem solved.
So, I thought, before I go out and buy a new sending unit I'd try dielectric grease on my sending unit connector. My oil pressure stays at just below 40 idleing on the gauge now.

No kidding?. And that's the only thing you did put dielectric grease on the connector?
Im going to try that today. Will let you know what change if any

Edit: do you have a theory on why that would stay near 40 at idle?

I bought the sending unit from O'Reilly's, so I don't think it's accurate, but it worked better than the one I replaced it with for a while then started to read low. I sprayed the connector with WD-40 and that would last for a while. The grease has worked for the longest.

Dielectric is great. I always use it on all my electrical connections whenever possible!

Thanks for sharing!

The thing that is missing in this thread is how you actually checked the oil pressure with a tool to make sure you don't really have low oil pressure at an idle. I get that you put some dielectric grease and it changed, but that just proves your factory gauge circuit isn't accurate. I suggest double checking just to be sure. That is what I would do anyway. At least that way you would know what it is for sure.
