Hey Nikhil, now that you have switched to normal petrol instead of 97 what is the difference you can feel?

I felt more vibes in the last 2 night rides. specially when running in the low revs , around 2-4 k rpm. I will switch to shell regular fuel to see how that is or to IOC xtra premium.

^is the manual specific to India?

Fuel quality in Japan/SEA is normally better than ours. Add to that, adulteration at the pump.

This factor might make or break my aspiration for the bike.

unless you are redlining every minute or trying to extract every bhp of your bike , normal petrol should be good enough for normal riding .

I respectfully disagree.

These are high compression engines (and high revving engines) so its best to stick to what's mentioned in the owners manual, whether one is pottering around town or blasting away on the highway.

While regular unleaded fuel may not show signs of degraded performance almost immediately (knocking, detonation, etc.) in the long run it can damage the internals of the engine and/or also the cat-con.

Its a well known fact that we are supplied with low quality fuel, adulterated with contaminants and also compromised on volume/quantity.

I wouldn't take a chance with my bike, no way sir. If i am spending a packet or two on a bike or a car, a few rupees more for better fuel and lubricants would hardly matter. But then again, this is me. Others might feel otherwise

Congratulations and welcome to the Yamaha family. Please request to join the facebook group for the Yamaha CBUs (message me on Facebook). If you know any other FZ1 owners...rope them in as well.

Use 97 octane whenever possible and 91-93 in a pinch (Speed / Xtrapremium are around 91 octane). Don't use Octane boosters. The engine is new so it will run a bit hot. This gets better over time as the parts "run-in".

+1. See below:

Aditya - Do you know where in Bangalore we get 97 Octane?

Asking since this would indirectly benefit some of the Bangaloreans else you can delete. Thanks!

97 Octane is available at the BP bunk (Speed97) on residency road (just before brigade road on the left).

Edit - IIRC, this bunk goes by the name Nagpal's.

This might help too - https://www.team-bhp.com/forum/banga...bangalore.html (Trusted Petrol Pumps in Bangalore)

Speed 97 is an overkill for fz1 as manual recommends 91 octane fuel. I think I will start putting in xtrapremium on a regular basis.

Thanks. Am already there in the group . Akhil had added me there.

First of all, My Hearty Congratulations to you!! FZ1 is a very capable machine and it can do many magics.

I read that FZ1 has 11.50:1 as compression ratio.This should make the choice of fuel much less and you would be forced to go for anything above normal petrol available around ( Atleast Speed93?? ) .
Now that you have switched to normal petrol, Could you throw some light on your monster's behavior?

[niks_devil666]

thanks.
I have already posted that manual says 91 octane. With regular fuel , the vibes were noticeable.
I will fill premium fuel (as posted in my last reply) and then see the change in performance.

Compression ratio is 11.5:1 right? I recall reading somewhere that higher compression ratio requires higher octane fuel. Just as a comparo, Ducati Monster 796's is 11:1 and the recommended fuel is 95 octane.

So, posing a general question here. On what all parameters is the octane number specified? CR would be one and I might be missing on several others....would be great if someone enlightens. Thanks!

[Sn1p3r]

^ the above post definitely is right but the confusing thing is why would Yamaha print 91 octane for this high compression ration engine?

From what I gather reading the Octane story is that higher the Octane the better engine management is able to control the burn and thus better performance/less vibration/better economy and torque/power graph.

Filling Octane 97 will be better than Octane 95 in Yamaha FZ1 but Yamaha asking owners to run with 91 does not make sense.

Nikhil premium petrol is not 95 but 91 itself with additives that are not good for your engine. I had a rather long discussion with my service engineer at Honda and this was the reason for ivtec engines Honda still wants owners to fill 91 normal available now in most metros (engine compression 10.5:1)

Gasoline : Natural Gas Companies : Gas Industry Jobs

I think you will be better off using 97.

Cheers!

Hearty Congratulations Nikhil !! "Kitna deti hain" ? :lol

Time to have a "FZ1 Delight" on MotoCafe's menu ?

And I hope you remember that I am yet to see the bike.
