I now have 11000 kilometers (65k miles) with original gear oil,no problems,but changed it out anyway (porsche states lifetime fluid) well definately noticed a diff,easier and smoother,was surprised.This car is a daily driver,not tracked.I did use porsche stuff.I also bleed out clutch fluid and brake fluid but no change noted on that,clutch felt the same,stil relatively easy to push.Just wanted to note gear oil changing is worth doing.Porsche told ,e not to do it as i am wasting money and will notice no change,wrong!
