I was told by a guy who previously worked at a Ford dealership that Ford issued a service bulletin for the amount of engine oil required in 3.0 engines. He said that the alert said to fill the engine with 4.5 quarts instead of 5 due to an idle engine shaking problem caused by the throws of the crankshaft slapping the pooled oil in the oil pan. Has anyone heard of this or a TSB
number that was issued?
that the "mechanic" was probably thinking about is the one that changes the previously used 5w-30 to a cheaper and CAFE friendly 5w-20. (which I think is a croc of **** in higher temps. But maybe it's just me.)
