Last week there was some let up in the weather and I turned off the AC. The jerks were much milder when I let go of the pedal.

I had been thinking what is going on - your reply partly explains it.

I hope your Figo is 1.2L petrol. If yes it may be due to the lesser power of the engine. Why I say so is my Alto 800 has this snag since new which in spite of many services still remains. Whereas my Altp 1.1 never throw such a symptom.

I too feel jerks if I leave the accelerator pedal in a hurry. And the jerks disappear if the pedal is left slowly.

This also holds true in my Alto 800.

Mine is a diesel - but I have heard that petrol vehicles are effected worse with this prolem.

Try idling the car for 3/4 minutes after starting without giving any throttle input. Idlle the vehicle while you adjust your seating , snap on the seat belt, connect the handsfree / bluetooth etc . D O N T switch on the Ac till the vehicle is in motion and ideally as late as a km run ( i know its difficult in the weather due to fogging ) Do try it one of the days , and notice if the engine braking is as pronounced as before.
It works wonders in NA diesels and normal turbo charged IDI and also CNG retrofitted cars.

I just added 40 ml in 40 l.. nothing significant, FE dropped by 1+ Km.

- did it happen with similar usage of the vehicle?

your observation is the first contradicting the reports so far - some people have said FE increased, some said nothing happened - but your goes contrary.

[panky12345]

Yes, identical usage of the vehicle. (diesel). I simply posted my experience.

Wow - something to go by - if there were a way your post should get 5 stars.

BTW how much does 2T cost these days?

Try it for 2 more times. And try a larger dose if your have the opportunity to drive fast over longer distance like an expressway and check again.
also add simple 2t oil Jaso FC rated. Like the HP racer 2t or IOC servo 2t . My guess is your FE may go up a bit but you 'll surely find marked smoothness.

In my 10 yr old Indica v2 I have used Shell advance 2t and Servo 2t, the servo 2t has noticeable difference, its smooth even at cool engine.

[panky12345]

I used servo 2T pouch 40 ml worth INR 8.50...

This is way cheaper than IFTEX then. Let me try it on my Figo - just got a tankful yesterday, let's see if I see a difference in FE on this tankful.

Thats the problem with this thing. Its the synthetic fixation.
A simple solution always seems improbable.
sERVO 2T is indeed the best in my experience too.

only few times I have added 2T oil in small quantity (~ 20-25ml) in my Xylo, diesel capacity of 55 ltr. Recently during a trip (ODO=85K KM), I added the whole 40ml pouch during a full tank. The drive was on highway, with speed ranging from 80 to 110. I can tell you of positive impact during the smooth drive, and the FE also bit increased. I would personally recommend 2T oil once in a while, thats what Im going to do!

I have even heard from many bunk staff, that many Sumo/Tavera/Qualis owners put a whole 200-250ml 2T bottle in the tank. Not got a chance to speak to such a owner / driver.

I did(and continue to do so) to my ancient diesel mills that are not Crdi tech and they don't have a cat-con either. It is noteworthy that the Sumo, Tavera/Qualis don't have crdi tech either.

For me it definitely resulted in a smoother engine(more pronounced when idling), bit more kmpl and throttle response.

Oh and it did solve a notorious starting trouble(which originally was due to FIP wear & tear).

I wouldn't even try it in my new cars though. They are complicated with sensors monitoring a lot of things and wouldn't want to mess with them, lol.

now I can say of speaking to such a person !
good to know about your experiences. would love to hear more experiences of 2T usage in modern machines.
