The ability to run BS-6 cars on BS-4 could save a lot of money for OMC's. It took almost a decade for all of India to shift from BS3 to BS4. It'll be herculean task to provide BS-6 fuel in all fuel stations in India by the government stipulated target of 2020. I am not sure though if it's possible to run high tech BS-6 vehicles on inferior fuel without messing up the complex systems.


"The government may nudge automotive companies to make Bharat Stage VI (BS-6) certified cars capable of running on BS-4 fuels. Such a policy could result in huge savings for oil marketing companies (OMCs) which are preparing for pan-India BS-6 fuel roll out.
Mercedes-Benz on Friday unveiled a BS-6 certified car which can run on BS-4 fuel.
“I am really happy that Mercedes-Benz has achieved this,” Union Minister Nitin Gadkari said on the sidelines of the launch event in Mumbai."

Tomorrow's news -

The roads in various interior parts of India - and even in parts of some of India's largest cities are so full of potholes, dug up by the metrowater / electricity people etc, that only a bullock cart would be fit for such roads. It will be a herculean task to make such roads up to the standards of an Autobahn.

Hence all BS6 / Euro6 cars sold must come with an attachable harness in which a bullock can be yoked for use on such roads.

Reminds me of the joke in the Ben Kingsley Gandhi movie, in which Gandhiji is sitting in an old car yoked to a bullock, and jokes to a visiting foreign reporter that he calls the car "Oxford" because it is a Ford and it is drawn by an Ox.

What's the point of stricter emission norms if fuel suppliers get a free pass?

[condor]

Chetan, exactly ! If BS-VI fuel cant be supplied, then there is no point in asking for BS-VI vehicles. Let them continue with BS-IV norms.

Having said that, I'd rather wait and see what the govt actually comes out with. No point in believing what's said in the papers. or media.

What's the point of upgrading the engines to BS-VI if they are made to run on BS-IV fuel. I believe if BS-VI complaint vehicles are made to run on BS-IV fuel, they won't comply with BS-VI norms. In reality they will be polluting more than what a BS-VI vehicle should. We the customers will have to pay more for our cars with no/negligible environmental benefits. This will be a stupid rule if & when implemented.

BS VI engines, if run on BS IV fuel, will indeed pollute more. But as per IIT-Kanpur's 2016 report on the topic of air pollution, passenger vehicles only contribute to 10% of emissions. The Oscar of vehicular pollution goes to heavy commercial vehicles and the joint Oscar for overall pollution impact belongs to the power sector, domestic cooking and garbage burning etc.

If BS VI vehicles run on BS IV and pollute more in the short term, it's ok if you ask me. But would this harm the BS VI engines?

OT - It however deeply concerns me that if BS IV diesel engines run on BS VI diesel, it'll harm the fuel injectors. For a Ford Figo, one fuel injector costs Rs.15,000 for the part alone. BS VI diesel will have 1/5th the Sulphur as BS IV diesel - I fear this may mean that fuel injectors will have 1/5th their former useful lives, due to lesser lubrication (the sulphur in diesel serves as a lubricant for the fuel injectors in diesel cars). How do people buy BS IV diesel cars today if they know already that beyond 2019 or 2020, their cars will suddenly undergo significant damage with BS VI fuel?

I have a very bad feeling about all this.
Soon we may have an announcement that only the metros will have BS6 fuel by April 2020, and the rest of India would be given a few more years ... since not all refineries will be capable of 100% BS6 fuels.

So much for environmental concerns.

Of course all this is a conjecture right now, things may not go this bad.

I believe this will definitely happen. When BS 4 was enforced by 2017, only 50 cities had BS 4 supply. In fact, I think rural India and even tier 2/3 cities still have only BS 3 supply even now, if i'm not mistaken.

I guess it is a premature to commenting on this. I read somewhere than Merc already launched a BS VI vehicle in India. I guess, what that means is that even with BS IV fuel, the vehicle meets BS VI emission norms. That means newer technologies to meet BS VI do not require better fuel!

[Durango Dude]

Govt of India almost always puts the Ox behind the Ford! They always lay down the laws first and address the ground realities later! When I got my first car a M800 it was fitted with a cat con and was advised to tank up only unleaded so the cat con won't pack up. But unleaded petrol was available only in a few bunks in the city and once out of city limits there was no unleaded to be found.

This is pointless! The rules should be followed by everyone equally. Before announcing the deadline, the government should have ensured that the oil companies have the capacity to supply BSVI fuel. I hope that the BSVI technology developed by each and every carmaker is good enough to take the BSIV fuel too without creating any problems to the engine, so that us customers won’t be the victim in the end.

So the question here is if someone like me planning his next car should consider diesel options?

[sgiitk]

I think BS-V was lost because of the OMCs. If need be shut down the sarkari monsters and switch of Imports as was recommended by the expert panel.

How does Diesel vs Petrol factor in?
The entire country today is on BS4 for Motor Spirit (Petrol) and High Speed Diesel (diesel used by most road vehicles).

The entire country will move to BS6 for both MS and HSD.

It's not really OT. The Renault Duster 110 version is already been suffering from injector failures. These piezo injectors are made by Continental and as per them, the reason for failure is the bad BS4 fuel specs prevailing in India. One injector costs you Rs. 26K.
