2.The most annoying part of driving diesel vehicle after driving Pertrol based super rocket Zen, I had difficulty and felt strenous driving a diesel vehicle. The main reason is due to the fact that you got to shift the gear all the time in Blr city traffic, unlike my zen which used to pull up from 20Kmph to 70Kmph in 4th gear. With Ertiga, when you are in 5th gear with speed of 60Kmph, if you fall below 40Kmph, you have to MANDATORILY shift down the gear and get the vehicle above 50Kmph speed before you can shift back into the 5th gear. Absolutely annoying.
For up shifting as well as down shifting we have recommended speeds for diesel car balance power and millage.
for City : up shift
1st max 10 kmph
2nd max 20 kmph
3rd max 35 kmph
4th max 60 kmph
I never use 5th gear in heavy traffic in city..
Millage is mainly depends on the driving style apart from condition of the car.
hope this helps..
I am getting 16 Kmpl in City(chennai) 19 Kmpl in highways( speed between 100-120 and occasional 140 too)
