Good Evening everyone.

Tonight on my drive home, I came off the highway and while stopped at a red, I noticed the oil light come on. Light turns green, I begin to drive and it goes off. Same thing the next 2 times I stopped and started. I got home and checked the oil, it shows more than 3/4 to the max. line.

Any idea's?

Thanks!

 

What are the RPM's on the engine doing?

Is there any oil leaking from the oil pressure sending unit?

 

Two possible problems here, one cheap, one expensive to repair. If it's the sending unit, it's a cheap and easy repair. If it's the oil pump, it's gonna be costly.
Years ago, my wife had this problem in her '95 Voyager. Turned out to be gunk in the oil pan and pump. It was a big repair.
Last year, my mother had the same symptoms in her '96 LHS. Turned out to be the sending unit. Check that first.

Good luck.

 

Before you spend much on repair, change your oil and filter. Perhaps add a quart of Rislone oil for a couple hundred miles before you change it. Once in a while it helps.

Also, an engine RPM below 500 or so at idle can cause the light to come on.

 

Information only to maybe give you to read.
I have 2 Chrysler cirrus cars with 2.5 Mitsubishi engines. I change oil & filter myself every 3-4,000 miles. I have very interment oil light issues. Sometimes the 2000 light is off for a few days & sometimes it’s on a lot fewer than 2000 rpms even. & goes off at higher RPMS

The 2000 has 175,000 miles and the light has been flickering (& often stays on after) engine got to operating temps at idle only ( aprox 700 Rpm reading the dash tach). My situation has been getting worse that now at times when I take off the oil light will stay on until it hits 2,000-3000 rpm and the shuts off.
My compressor will need to be UN-bolted and moved to the side to get the oil pressure switch out & re-installed. So I have not replaced it yet.

The second car is a 1999 with 115K and it’s starting to have the same symptoms, however they are much less noticeable.
I changed to 10-40 weight oil and that seemed to help quite a bit, but the engine is not having any other issues,

Neither engine is knocking at start up AND neither is using oil …so I am not to worried for the time being

 

You can also try 1/2 a can of seafoam. It will clean out any sludge that might be lurking around the sending unit and in the oil journals. Put the other 1/2 can in the gas tank to clean the fuel system. I buy mine at NAPA, works wonders!!
