Any body have any details of BSIV norms. I found this on SIAM website.

From 1st-April, the fuel in 13 cities will be of BS-4 compliant.
Do anybody knows if there is any impact on putting BS-3 compliant fuel in BS-4 complaint vehicles or vice-versa.

I could find -
An executive from Society of Indian Automobile Manufacturers (Siam) quoted,

We have a particular concern about the unavailability of the correct fuel from April 1. The current range of engines is tuned in such a way that they can handle both types of fuels (BS-II and BS-III). The next generation engine, of BS-IV, will be more tuned to handle BS-III than BS-II. If there is a sustained mismatch in fuel quality for about a month, then there will definitely be a very negative impact on performance. Most likely, there would be a knocking tendency while acceleration, much reduced fuel efficiency levels and a long-term impact on the life of the vehicle.

Oh now the older vehicles face a serious threat here!!

 

[ilango[speed thirst]]

Do they measure them seriously?

 

[blackbeauty]

So, if there is any mismatch of fuel in BS-IV vehicle, it'll have negative impacts??
That means fuel compatible for BS-IV vehicle is needed or it'll happen if BS-III and BS-IV compatible fuel is mixed??
Or the older vehicles will be facing the problem??

 

[RSM]

Actually older vehicles are ok with BS-4 fuel.
The problem might happen, if new vehicles (BS-4 compliant) uses older BS2 or BS-3 fuel.

So, if there is any mismatch of fuel in BS-IV vehicle, it'll have negative impacts??
That means fuel compatible for BS-IV vehicle is needed or it'll happen if BS-III and BS-IV compatible fuel is mixed??
Or the older vehicles will be facing the problem??

The problem is not mixing the fuels of the two types,but the sustained or prolonged use of the lower grade fuel.

In our tdi vista , the sign glowed for a few second few days back.

All were worrried ! its only after i said its due to fuel , they were relaxed.

It glows in a innova too due to adultrated fuel

 

[cooldhaya]

Oh so doesn this harm the engine??

 

[ilango[speed thirst]]

No major harm , rest of fuel will equalize them

it will harm only if you fill again and again from the same fuel station.

@350Z, Are you sure about the list?
Palio is also going to be discontinued from 13 cities. Also i am surprised to see Fabia here.

 

[350Z]

Skoda Fabia 1.2 HTP Petrol Model will be discontinued, This information is from Autocar. And Yes, Add the Fiat Palio to list too.

Drive Safe,
350Z

 

[Aditya]

Well, my 1.4 will have company ... it is already discontinued!!

 

[RSM]

That means, all Fabia Petrol will be discontinued. I feel bad, this is heck of a hatch. Fabia Diesel is costly, no idea what is their plans. May be a refreshed Fabia?
