How many miled for next oil change?

The initial oil change is important, because after you break in the motor, the oil will have trace amounts of metal shavings in it from the transmission gears, and fiber debris from the new clutch plates. The oil needs to be drained so that the debris doesnt flow through the motor and cause excessive wear on the transmission and motor. After your initial oil change, it's recommended to change it about every 3000 miles or so.
