2000 Cadillac Eldo with 93k on it. Uses oil and antifreeze.
I've used approx. 5 quarts in the last 8k and always have to "top off" the radiator at that time. I never smell coolant or see coolant OR oil under the car. No coolant in oil (on stick or at change). The tailpipes get blackened and so does the rear body moulding around them. Doesn't overheat ... and has NEVER overheated in the 10 years I've owned it. The car is in good shape other than this .. which obviously irrelevant if it doesn't run! TIME to shed it??
