My suggestion is to dump the FF and refill with MC 5W50 and wait until at least 3000 miles before using Red Line per their recommendation ... just my 2c.i just bought some redline 5/50 - it says NOT to use until after engine is broken in - after 3000 miles. what does everyone think???? my 10' is at 600 miles, do i need to wait until 3000 to use this oil??
