2.4 4cyl Within the last 2 yrs, fuel economy slowly decreasing from 32mpg hwy to 24mpg hwy with 21mpg combined. Within last 12 months, major tuneup (3rd since purchase) (plugs, oil&fuel filters), new O2 sensors and Passed SMOG no problem. Idles and runs smooth with plenty of power and acceleration. Oil & filter change every 3,000-4,000 miles since purchased car with 29,000 miles from dealer (lease trade-in). Need to add (1) quart every 1000 miles or so (since purchased).
Any ideas as to decline in mileage?
