(2) What’s the best rev range for engine's performance? I read in the manual that initially (until 1000kms), it should be kept between 2-3k, and I always kept it around 2.2k. But the driving experience is better (because of the vibration) if I keep it in a higher gear and at a lower rev range (1.7-1.9k). Which one is better?
(3) I feel that gas pedal becomes very sensitive in lower (1 and 2) gears, any small release/press causes a jerk if I keep the clutch at the same level. I guess this could be due to my inexperience, but I found that if I don’t release the clutch completely (so that tyres and engine are not completely connected) then the gas pedal is less sensitive. Is that something OK to do for preventing jerks? Or it causes any harm to the clutch etc.?
Firstly. I have not driven a pertol car of a long time. Last I drove was around 2 years back but most of your questions are in General. So I might be able to answer to my best knowledge.
1.) Yes, It is normal (Atleast in diesel). How old is your car. In my earlier car(diesel i20), I had this vibration until the car had run-in for arnd 1.5 to 2k kms. After that, it gradually reduced and was pretty smooth till above 3k rpms as well. Do notice if it is getting eased out over a period of time. I feel the same in my Verna as well. but a lot reduced since the time I just got out of the showroom.
2.) For a balance between performance & fuel efficiency. Always. shift between 2000-2500 rpm. and check the lowest RPM in each gear below which the car starts jerking or lugging. and upshift accordingly. You need not look at the odo all the time. with expirience you will get to know and you will start shifting accordingly.
3.) The problem you are facing is. The release of clutch and the pressing of acc pedal should be in sync atleast for 1st & 2nd gears. Whats happening in your case is you are pressing the acc pedal a lot more than you are releasing the clutch and when you are releasing the clutch(Too fast I guess) you are getting a feeling that the acc is too sensitive and the car just zooms ahead a lot more than you expect. (If you own a bike, you would have experienced this, accelerate lot with clutch fully held and release the clutch all of a sudden, the front of the bike takes off - Only a example please dont try it)
The best way to do until you get used to is, release only the clutch upto a point where the car just moves and then press acc pedal slowly and release the clutch.
It takes some time to get used to these.
