I am looking at buying a 1994 Eclipse 1.8 as a 3rd car to replace my 93 Mazda. This car has 150,000 miles on it and the owner had an oil change on 11/21/2006 and the oil is already very very dark and a quart low, is this indicating the car has a problem? It looks like there is some seepage of oil on the valve cover gasket, the engine itself runs strong and smokes a little. I had a 1989 Cadillac Eldorado 4.6 and I put a bottle of stop smoke in the oil and never had another problem. What are your thoughts about this Eclipse? Do a Auto Rx treatment and go from there or just stay away all together, the selling price of the car is $400.
