I have a question. I have a 1992 Cadillac Deville. I am wondering how many miles should I put on it before I change the oil. I like to change it every 3000 miles to 3500 miles. My dad wants to run it 4000 to 5000 miles before changing the oil. I am afraid that is to much as old as the car is and the motor. Their has been no motor work ever done to it. I have changed all the water parts out that is it and a tune up changing the spark plugs and the distributor that is it. Oh I also have another question. My water outlet was leaking Monday. Pulled it off Tuesday the thermostat was gone all that was left was the thermostat gasket. I found the bottom piece in the upper radiator hose down towards the radiator. I am curious if it is in the radiator. I have not seen it and can't find it. At least I got my heat back. I haven't had heat in 3 years I thought it was broke but I could not tell. Thanks.
have the same problem?
