Recently purchased a 2019 F3L and the dealer recommended bringing it in for the first service at 600 miles. I asked why so early and he said they have found many vehicles have metal shavings on the oil drain plug due to engine break in and it is best to get those flushed out early. The rest of the maintenance is according to the schedule. Is my dealer full of it or have others found these shavings? Also, isn't that what the oil filter is for?
