@Asifali2016, if you drive Vitz in Gear *S", gear oil will heat up fast , so try to run it like 5 mins, but exact time for short run or long run, i cannot comment,
Try use "S" where u need to take over/changing lane, don't over push the vehicle, do moderate 60-80% push, technically you are driving in short gears with high RPM, rest u can imagine, how it effects gear n engine
