I have a 98 deville and the oil light keeps coming on and it says STOP ENGINE and I know it's got oil because I just changed it and the dipstick says it full and I don't want to put more oil in and risk damage. Thanks for any help

Very well could just need new oil pressure sending unit. Inexpensive and simple.

Adding oil won't help anyway.

Use only an AC Delco replacement.

It's threaded into the oil filter adapter.

Here you go - and this is an engine problem, not electrical (in the strict sense) - You'll get a LOT more help with this type of question up in either the Deville or Northstar forums.

The replacement is much easier if you remove the lower air deflector and oil filter, then the oil filter adapter. 2 bolts, 2 O-rings. Bolts go to 12 lb/ft on replacement.

You are confusing oil pressure with oil quantity.

We have Brand new oil filter mounts with sending unit $85.00 includes shipping. i might be able to talk Jake into selling just the Sending unit.

sending units are like $15 or less ... at list price ... shipping wouldn't be worth it for just about anyone

might as well just get it at your nearest dealership
