Re: rattling sound after adding one quart of synthetic...
Oil shouldn't cause this symptom. (syn. oil and reg. oil - their is only a 1 percent difference between them) a rattle noise could be a valve rocker arm OR (the rattle i had) the catylitic converter. the honey comb stuff broke up into pieces inside.
past Lincolns I hav e owned an 81, 85, 88 and 1996 Town Cars and each time I put thjat Synthetic **** into the 81 and 85 TC they started to smoke. I would not Reccomend it for engines with more than 100,00 miles
