I have done more than 4-5 trials both with normal & xtra premium By filling Rs. 200 petrol in each case.
Invariably reading was 200 & 180 kms approx for Xtra premium & normal respectively

IMO a full tank to reserve trial would be better as it would factor in the variation in riding style/conditions/etc!

Can anybody explain this discrepancy

Thanks

Impossible.

How many liters of Xtra permium did you use?
Did you fill full tank or try doing it by shifting from Full to reserve and then measure?

There would have been a minor increase in mileage, however if you were seeing difference in performance you might have held on a wee bit longer to the pedal, thereby nullifying the xtra mileage which you would have received.

I usually fill up the tank 1st week of every month.

I've tried Speed and normal petrol in my Bro's WagonR and my Zen there was not noticeable improvement is fuel efficiency. But yes it felt smoother.

@yzfrj: This thread is for bikes, we have other threads for using premium fuel in Car

I was filling Xtra Premium in my Pulsar 150 for some time. I had some starting problems. Got the carb cleaned & float re-aligned.

The Bajaj guys recommended me not to fill Xtra Premium or else the problem will pop up again. They told premium petrols are having more density, so they are harmful for the carbs. Sticked to their advice for the last 6000 KMS. No problems so far.

But the FE was better(4 KMS more) on Xtra Premium than normal.

I have a 2003 Thunderbird.

Over time, I have experimented with different kinds of fuels from reputed petrol pumps in hyderabad and elsewhere. The running costs are almost the same whichever fuel i use ( As i get slightly better mileage from teh premium fuels)

The bike feels smoother with the premium fuels. So, I tend to fill my tank with IOC Xtra Premium.

I have also tried the Shell premium a few times. It does not financially work out for me but the bike does feel really really smooth and peppy.
