Asked by for the 1993 Lincoln Town Car
Could either be a clogged oil pump screen or the oil is broken down.I've had good luck changing oil with castrol and a quart of lucas oil treatment.If you have high miles i would use 10/30 or 10/40.If you do add lucas,put that in first because it's a little thick.I did that combination with my 95 tahoe and now my engine doesn't make noise in the mourning and burns way less oil.
