Is expensive petrol better

[YellowDog]

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

I've not tried any 98, just 95 and did notice some difference and certainly better fuel economy.

After comparing it to 91 and also reading the manual, I decided to stick with 95.

94/95 is the norm in Europe with 98 being the higher octane stuff. I don't think they use 91 much in the USA either.

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!

That would be my new bonneville also.
Well 9.2;1 anways so close.Runs better on 91 for sure.

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.

Yes that works....tks

What do you put in the CT110?

They do. Its their 87.

It's the firms bike and they put in 91 only.

I didn't know that.

I didn't know that.

USA (AKI/PON) --- Europe (RON)

87 = 91
89 = 93
91 = 95
93 = 98

I didn't know that.

Yup, it is because the Americans use MON (Motor Octane Number) rather than RON (Research Octane Number).

MON is always a lower number for exactly the same fuel.... I'm sure you can google it to find out the way MON is worked out.
I could quote from memory, but it was a while ago...

USA (AKI/PON) --- Europe (RON)

87 = 91
89 = 93
91 = 95
93 = 98

Okay, stand Corrected... AKI/PON, that is a new one on me....

Off to google myself

[quickbuck]

Okay,
Here it is......

I am surprised by the small difference in power shown on the chart but that just shows how impressions from riding a bike can be misleading. I filled the Speedtriple with 91 once and the motor pinked (knocked) really badly under power. Now I put 95 into everything - at the price of petrol the extra 5 cents a litre doesn't seem worth bothering with.

[firefighter]

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

What do you run your hornet on? You tried any comparisons with 95/98?
I've always used 91, haven't bothered to try anything else.....

Also how are the PPS going? Still getting good mileage out of them?

2.42 quid/ litre? FUUUUUK That's $5.8NZD/ litre.
