Best Fuel?

**SuperDave** · 2nd November 2004, 16:20

I was curious as to what fuel (octane rating and brand) others prefer to use. Those who do have a definate preferance to a particular fuel, why so?

I was wondering what the best brand of fuel was to use in my bike.

Generally what the manufacturer recommends, or as close to it as you can get.

there is no best brands as I have learnt from my car days. Every engine likes different fuels. Some engines that are designed to run on lower octane runs no better on better fuel.

Its a matter of trial and error I say.

This has been done a few times before.... 91 octane is the cleanest fuel (other than 98 octane from Gull or Mobil, i think)

Safest to use what the manufacture recommends.....

But Nicko uses 91 octane in his 600, and still does 1:01's around Puke, so HP doesnt really come into it.....

HP only comes into it is if ur engine is made to run on 96 and ur using 91 and getting some detonation then ull loose a big of power used 91 but generally not much

i accidentaly filled my bike up with 91 the other week(i use 91 for my cage), it atually made a hell of a diff, there was so much more response to the throttle than with the 96 which i put in this morning just to double check, and sure enough its different throttle response.
I've filled it completely to the top so im gonna see what kind of economics each one has coz it made heaps of diff to my car to change to 91 over 96, so much cheaper.

I like mobiel's petrol, its very clean

I want to try BP's one but dont have one near by to try it

**Blakamin** · 3rd November 2004, 09:23

I normally run BP 98 but i might change to 91 next tank and see what happens... the yamaha like 96 the best, the honda loved 98... will have to see what the Duc prefers

Thanks for the comments, looks like it seems to be the best just to try them out and see for oneself. My handbook says 96 octane or higher, and I've only filled up with premium at Gull and Mobil, maybe ill try that 98 from BP you guys mentioned.

I run my Bandit on 91 (manual recomends 91 or higher) with no problems. Have never tried 96 or 98 as I wasn't sure if the higher octanes could damage the engine. Since I've only now bothered to read the manual I may as well give 96 a go. I've not found any differences between brands.

**StoneChucker** · 3rd November 2004, 19:29

The manual is the book to follow. As I see it, if it says 91 or higher, then use whatever you like, 91, 96, 98, whatever. If your book says 96 or higher, using 91 would be reckless imho, and against the manufacturers reccomendations, a possible hurdle in warrantys if anything goes wrong

i normally run what ever i find the bike to run best on.
i have found that:
91, get better top end and easier starting in winter
96, better bottom end power
98, running more smoothly and warming up faster
AV gas is best run as a mix (say 40 -60 98octane) and runs slightly better than 98.
this is only my opinion from riding over the years and from owning many bikes.
i personally run my bike on 98, where availible or if i am feeling rich and going on the track (the "legal" part) i will run a mix of AV gas and 98 octane

last bike i had was a 600SS, and when i first brought it ran on 91... mind you like a hairy goat compared.
sorry, but those bikes have a thrist for the expensive stuff.

people have issues running AV gas in their cars, cause AV gas burns much slower and hence create more heat in your engine. Have know to caused burnt valves and melted stuff...
