hope i dont go off topic but can someone tell me which is the best fuel for a 99 zen (carb) ?
Normal 87 octane or IOC 91 (recomended). 93 oct on our cars is a waste.

Harsh ride as in engine-wise? What exactly do you mean by that. Is the engine making some sort of noise? Or does it jerk?

what exactly do you mean by harsh. if its jerking often its either bad or adultrated fuel or your fuel pump is chocked and hence the fuel isnt flowin properly hence the jerking.

so what exactly do you mean by harsh ride , engine - wise??

Best for your car is what your manufacturer suggests. High Octane does nothing but prevent knocking. It is nothing as if it is "better" and more pure fuel. So it is rather wasteful. If it has additives which lubricate the engine better, that is a different case.

IOC extra premium was the best that i have used on my zen.i feel its better than the reliance 98 octane.

but as ther are not many IOC outlets selling 91 octane,my car does well with POWER

Ok here's more ammunition for IOC extra Premium guys. CHecking the auto fuel policy on Ministry of P&NG website, it is interesting to note that policy mandates two kinds of petrol, normal and premium. Min. RON rating for normal is 88 and for premium is 93 for BS-II vehicles, and for Euro-III generation, the settings have been upwardly revised to min. 91 for normal and 95 for premium.

Now, even today and well into Euro-III era, normal petrol from all three leading cos. (IOC, HP, BP) continues to be 87-88 (as per their websites). What is incensing is to note that even Power and Speed have same octane numbers, despite their companies marketing them as premium (Note: Premium fuel is red in colour, normal is orange, as per govt. policy)

IOC mentions on its website that XtraPremium is 91 octane. Good, but it should be 95. Others (HPCL and BPCL) are even bigger cheats, they are branding their fuels as premium when in effect it doesn't even meet the normal fuel requirements as per the policy.

Actually this excerpt from auto policy puts it as good as anybody could:

"Petrol of 89 RON and 79 MON and having all other properties as the unleaded regular
grade indicated above shall also be available for meeting requirements of the older vehicles
which will be conforming to pre-Euro III equivalent vehicular emission norms."

So Cheers! We are being fleeced!

Fully agree that we are being fleeced... but wasn't the Euro-III era postponed to October this year, mainly due to the objections of the oil companies that they needed more time to make the higher octane fuel widely available?

And greenh0rn, could you post the link to the auto fuel policy that you found?

Thanks!

Don't know if this is a new development, but there is also a Shell pump (in Bangalore) on Lavelle road, next to Sunny's.
