What kind of oil does a Cadillac 97 use?
And make sure they use an ac delco filter. The 15W40 is thicker and will raise your oil pressure. Rotella and Delvac make 15W40, its a diesel oil and has more zinc, which your 97 engine with its 32 rubbing element lifters will love. Then have the oil pressure switch changed and the connector cleaned and tightened.
What kind of oil does a Cadillac Northstar take?
If they used a 5w20 that is common todays newer engines by accident your oil pressure would drop, your engine takes 10W30 dino oil. Do not use synthetic oil it flows 7 times better and as a result could lower the oil pressure in an aging NS, I wouldnt use it in the 93 to 99 Northstars.
Why does my car have a low oil pressure?
Low oil pressure can be caused by a number of things including a low oil level, excessive clearance between internal engine parts or problems with the oil pump. A faulty oil pressure switch/circuit or a bad oil pressure gauge could also be to blame.

Why is my oil pressure so low at idle?
The oil pressure switch is attached to the oil filter adapter behind the front exhaust manifold. If this is a low pressure problem at idle, I believe is caused by the oil manifold gasket where the seals have deteriorated and pressure is lost internally. It is quite a big job.
What should I do if my oil pressure is low?
Do not use synthetic oil it flows 7 times better and as a result could lower the oil pressure in an aging NS, I wouldnt use it in the 93 to 99 Northstars. Does your engine sound like the lifters are noisy, ticking or clackety?, indicating possible low oil pressure?
