As I posted elsewhere (one thread below at the moment), I've just purchased a 93 Altima for 500 smackers. It has 352000 kms. The guy I'm buying it from has had it for about 9 years, He's an older guy so he probably didn't abuse it, he used the car to go back and forth to work so most of the mileage he accumulated were highway miles. I fired it up when I was looking at it and the motor is silent as far as engine noise. It's been sitting for about a year, but it's been started and driven occasionally. I'm not going to be getting it on the road for a while, I'm broke right now, but before I do, I'm changing the oil. I've read several comments on various other websites and message boards that the KA24DE has a tendency to shear oils. I figure with my high mileage engine, I don't want the oil to shear down, the motor needs the extra protection a heavier oil would provide. I was thinking of running some Esso XD-3 synthetic 0w40 and a Quaker State oil filter, Maybe a Baldwin if they're not too expensive. Would this oil and filter combo work well in my well-seasoned engine?
