Driven by an old lady from day one and never seen a winter, but uses oil and everyone I have talked with that had owned one said the same thing about their 89 caddy using oil as well and since then, got rid of their cadyy. Anyone else having the same problem with this 5.0 litre engine. great gas mileage but terrible on the oil. using Lucas oil now and 10W40 oil which seems to help a bit.
That's it for me.
