Noises problem
2001 Lincoln LS 6 cyl Front Wheel Drive Automatic 81000 miles

when I go over a hill or accelerate I hear a rattly/knocky noise. Had oil changed recently. No leak. Oil levels ok. Told to try an oil additive to quiet it. Works for a day or so then stops and its really loud again. If I let car reallllly slowly get up to speed it is better- meanwhile Ive infuriated every other driver on the road: ((
