Hello to all. I bought a new Crown Vic back in 1998. First NEW car, but was not at all new to vehicle maintenance. I took and do take very good care of it even today, although I've let the oil change intervals stretch out to 5000 mi. Always did 3000 mi oil changes. Car has high miles approximately 231000. Still runs like new, pulls hard, and cost me very very little in maintenance. I have noticed early on in its history that it liked to use more oil on the freeway than it does putting around the city. The last 2 years or so the oil consumption has gone up considerably. It uses 1 qt per 1000 miles. Not terrible for such high mileage, right?
What troubles me is I really don't know where the consumption happens. It does leave a tiny drop wherever I do park it. Often times I check when I turn the motor over to see a blue cloud of smoke at the tailpipes, - never seen any. When I change the spark plugs and inspect the old ones they always look clean and never have any oil fouling. If you were to look under the oil cap, the motor is pristine and clean. Any thoughts?
FWIW, I've never had any oil brand loyalty. I'd go to Wal Mart, find the best deal on a 5 qt jug, be it Castrol, Quaker State, Pennzoil, SuperTech, or what have you.
