I'd like to eat my own words here . After a few tankfuls, Speed 97 definitely makes a big difference.

The engine revs faster, the tiny bit of turbo lag that existed before is completely gone. The acceleration is more manic and idle is significantly quieter.

After persisting on it for a while, I'd definitely not mind spending the extra 10 bucks on Speed 97 now.

@reignofchaos; I am sure your engine is designed for the European Premium, ie 95RON. So 97 is closer.

It is no great shakes, since when I was a student (1973-76, no Unleaded then) my 'ornery Ford Escort 1300 wanted 97 RON (**** petrol), but ran quite happily on 93. My boss had a BMW 2800 which wanted 100RON (*****)which used to be available at some pumps. Basically the pumps had 2* and 5* and a mixer to give what you wanted.

Why no BS-IV Premium then?

Sorry to bump an old thread.

I need to know the actual RON number of Speed 97.

Does anyone have a definite answer?

Tried on the BP website and , and I couldn't find specs.

Basically I need to know if Speed 97 is actually 97 RON, so I can tune my car accordingly.

Thanks for the help

Very difficult for anyone to corroborate unless he runs a RON test engine to determine the knocking.

Till then we have to trust BPCL when they say it is 97 RON gasoline.
By the way every refiner in India today has the capability to give you 99 RON gasoline. easily. So there is very little to doubt here.

Just out of curiosity, what are you going to tune/change to accommodate 97 RON?

If you car was designed to run on a lower RON number, putting 97 RON into it isn’t going to make a difference unless you are able to change the compression ratio.

If your car is equipped with a knock sensor it will adjust to the RON number within reason of course. Adjusting downwards is relatively straight forward.

I'm getting an ECU reflash for my 997.
I need a custom tune as i have improved the improved the air intake and exhaust.
So having the RON of the fuel i use (Speed 97) as close as possible to the actual, will allow me to get my money's worth for the custom tune.

thanks for the help

Just use 97 from a reputed pump and go ahead with the tune. You should be alright.
As already stated, if it has a knock sensor it will retard the timing to adjust.

Depending on the tune, you might not need a custom one. Though custom is recommended, as long as your air flow is standard supported by the tune, and whether the exhaust is supported as well (as in 3'' pipes de-cat or catted whatever you have, just check with the tuner), you should be able to buy OTS tune.

You can get a 97 RON tune and use Speed 97 without any issues. I myself and many others whom I know have done the same.

Could anyone advise on the availability of 93 and 97 Octane fuel in Hyderabad.


i am getting a high HP RD350 built and my builder will need this information.

Tanked my Mini up with HP Power 99 a few days ago and can report that the car is performing noticeably better than it was on Speed 97. Never expected it to make much difference, but it has. Power 99 was also a few paise cheaper per litre than Speed 97, ironically.

What is the RON (Octane Value) for standard petrol available in IOCL, BPCL, HPCL.

Additionally whats the value for IOCL's XtraPremium petrol.

Normal/Basic RON value is 91. The XtraPremium, Speed or the V power don't increase the RON per se but add certain additives.

I was searching for Speed97 outlets in Bangalore and I found only 2 as per their website. One was the one in Residency road that everyone is talking about and the other one is an outlet in Hosur road. Sadly both these bunks are 10+kms from my place. Is anyone aware of either Speed97 or Power 99 outlets near HSR? Anything in a 5-6KM radius maybe.

Which pumps consistently stock Power99 in BLR?
