BP Ultimate?
 

I know this issue has been aired before, but only (as far as I know) with an SV bias.

I always whacked a tank of 97 unleaded in the SV every 5-10 tanks full as I was lead to believe the detergents are good for the engine. So stuck with it knowing that there was no performance gains.

This morning I was almost on fumes on the CBR and pulled into a petrol station and decided to go for BP Ultimate, just thought about keeping the clean engine and nothing more.

The question is can the performance of the CBR-rr be affected by the better juice?

I got on it to come home and the thing felt more lively than before, I was thinking no can't be, but try as I might to be objective I definitely thought I felt a difference.

So did I?

is it a higher octane thats probably what does it though i dont know didnt really do much for the curvy sv havnt tried it in the pointy though a rr's a different beast altogether.

Interesting you should mention this....on the CBR I have found that if I use super UL I get around 15-20 miles more to a tank.

I have also found this on some cars which I've tried it on too...

On the M3 I used to have, it did make it run sweeter, cant say I've noticed a difference in the CBR (apart from consumption).

I know that on a pointy it makes no performance differnce due to knock sensors or something like that but wondered if the Honda was different, it definitely felt it.

Yeah I thought it may be so, but I didn't expect a difference in the first place which threw me a bit.

Maybe, but not in all circumstances...

I do a regular trip from Cornwall to Yorkshire - 330 miles each way, almost all motorway / dualie. If I use 97ron in the Audi, I tend to get 470 miles to a tank. If I use std UL I get 430. I don't notice any difference in performance, but the range improves.

Happens every time I try it.

Read an article in a car mag once, they tested shell optimax, tesco 99ron, and bp ultimate. the car they used was an astra vxr, the tesco gave biggest gain narrowly from shell and the bp fuel actually decreased power slightly (bp claimed a dodgy batch of sample petrol). From what I can remember the tesco and shell gave the car an extra 10bhp (approx). The article also stated that the engine ecu takes about 60 miles for it to register the different fuel octane, so if bikes react in a similar way it is possible that you felt some gain,although maybe not straight away.

Re: BP Ultimate?
 

I did find that BP ultimate made no difference in the M3, but optimax and other super UL's did give a slight improvement.

Does your Audi have a knock sensor? ...

As for your pocket, is/was the Super unleaded <9% more expensive? :scratch:
