Is expensive petrol better

[LBD]

The below 3 images ae coppied out of the August 09 Performance bike magizine....A good article on the differences between 3 commonly availabe petrols from BP....

Might be a website thing, but these are hard to read....Copy image and paste on desk top and they are good and clear...

I think it is relatively well accepted that unless your engine is made or tuned for higher RON fuel (e,g. has a higher compression ratio) then you wont gain much.

Good read. Thanks for posting the info.

Yes that is the case...1.4 % between 95 and 102 octane in a performance bike...

Good to have some facts on this as I have read a few treads on this and its been just plain confusing with so many different opinions on it. Looks like I'll stick with the cheap stuff, Cheers.

I read - 1100 quid for a bloody Power Commander!!!!!

Higher octane petrol is better.

BUT EXPENSIVE PETROL IS NOT BETTER!!!!

I read the same article, I know people say it shouldn´t make much difference going between 91 or 98 or higher, I always found my bikes felt a bit peppier on 98. I have no idea if its to do with the source/quality of the fuel or the octane rating. Maybe someone in NZ with a Dyno and some spare time could do a comparison between the 91 and 98?

Dunno about economy and I don't really care that much but my 14 definitely prefers to be run on 95 opposed to 91.

I do think that the bigger engined bikes benefit from the higher octane. And I also think it is more than 1.4%.

It could just be psychological!

Paul - try Control + in your browser and the image should zoom. Much easier to read. I have to do it with quite a few sites these days.

I read my bike manuals - and they tell me which to use. GSXR specifies the rating to be a higher Octane, than my SV650.

Have you tried your Tiger on 98 YellowDog? I've tried it in the S3 and found it more economical on 95.

Yup, because every website person has a 24" or bigger monitor...
And we all surf the net on Lap Tops with a 15" at best..... Well, mine is 16.4, and I have it zoomed to 125%.... just so everything is as "big" as it is at work!

Anyhow, back to the fuel debate.....
91RON is recommended for engines of less than 9:1 Compression Ratio...
How many bikes are that low???

Yup, only the 2-strokes!

tried my bmw on 91 a few weeks back and it did not seem to make much difference.

the petrol head in me is never sure though ?

this thread raises a good question, i would love to run both my bikes on the cheap gas, i might experiment more
