Hareyan- I've been an aviation engine mechanic for decades. These "sparkles" are completely normal and an early oil change is a waste of money. The oil filter makes sure clean oil is pumped through the engine so no oil flush is required. Drive the car at varying engine speeds during the first 1000 miles. This allows the bearings and rings to get the proper seat/fit to allow for a long efficient engine life. This period will create metal shavings or sparkles in the oil from the pan. If you see a lot of sparkles on the 3rd oil change or after 10,000 miles then there is a problem the dealer must investigate. Cheers
