it depends on how cold the engine is..
but 20 seconds sounds a bit less to me..

Thanks for answering. This is the umpteenth time I had written something and the session got timed out.

the throttlebody also needs to get warmed up slightly with the engine coolant.. in very coldplaces this would be a concern but not in india..but still the extra warmup helps in oil lubrication, bring o2 sensor to operating range and heat the TB also..
(but safe side our indian engines also have heated TBs)

Hi all

When i'm driving my Safari 3.0L in bumper to bumper traffic, i usually dont use Accelerator much unless needed.

I release the clutch and the beast moves effortlessly then i stop using brakes and move back to neutral.

and it goes on like that always as i have this bad habbit of using accelerator only when needed in bumper to bumper traffic.

and its relaxing also to use only clutch and brakes.

Please advise if it is a right thing to do or not ?

will it trouble any part in machinery ?

Looks perfect to me. I use the same technique. Why do you call this a bad habit?
Only other thing I do is that if I am on a down slope in bumper to bumper traffic, I slot the gear to neutral and release the brake to allow the car to roll forward, then brake again if needed. This is even more relaxing to the body.

Thats the beast's torque doing the work. Nothing wrong with this as long as you dont feel the engine being strained (rpm going too low etc.).
