Default very high oil pressure reading after oil change

Hi all,

Finally, a potential problem i can post about! I've been a member for a while with very few posts because my Bonne is pretty much as reliable as a sunrise. 165K and going strong.
I've been driving a lot lately, around 3-4K miles per month, and stopped into a place for a quickie service. got the oil and filter changed as always, except I usually use Max Life oil, and this place didn't have it. So it'* got regular 10-30 Havoline and Purolator filter. I'll change it again real soon as I was overdue and the oil was pretty dirty.

Anyway, the oil pressure has ALWAYS run at about half mark at idle and the 3/4 mark at cruising speeds. Immediately after the change it went close to the 120 mark and it hasn't gone down to the 3/4 mark yet under any conditions. I drove a mile and went back to ask the guy about it. he checked and said everything was OK,. it had the correct filter blah blah and it must be a bad sending unit. I watched the guy pump 10-30 into it.

Could it be a coincidence or something they did? I can't imagine what, but it is just disconcerting to suddenly have something different with old reliable.

I should mention it is a 97 non-SC car.

Thanks

Mike

You need to replace your oil pressure sensor. It'* an easy fix. It'* located right above your oil filter.

yes it is an easy fix, it fixed my problem which alerted me on my DIC saying check gauges oil pressure low, that went away but I have 2 problems my actual gauge is broke too it doesnt reset stays right above 40 and never moves so I can only assume if the actuall oil pressure was bad the DIC would alert me.
