I have a 1997 civic with 109k on it. I drive 60 miles (38 on I-15) every day to work (120 miles round trip). Everytime I change the oil in it about a week later the oil is down 2 quarts and its real dirty. This started about a year ago. I have just been replacing the oil that has been lost. The car has no loss of performance (that I can feel, power or mileage) but does make a screaching noise during acceleration. I have yet to change the timing belt and when that is done the water pump will get changed, which I have been told will fix the screaching noise. Anyway I was worried that my K&N cold air intake was letting to much "junk" into my engine. Is this possible, or is it something completely different?
