Cruisers - What octane fuel do you use?

[rainman]

I usually use 95, but for no particular reason. I ran the bike on 91 when I first got it, and I can't say I noticed much difference...

Maybe I should go back to 91?

[homer]

how come my manual says recommended fuel 91 or higher
I dont really think it would matter which you use
Also if your engine is low compression it wont make much if any difference wheather you use 91 or 98
the engine just wont make more power
you need to have higher compression to get a difference
my manual says for a canadian model bike use 87 octane min
and the canadian bike are slower to ,Im guessing this is because of less compression again .

91 in the VTX , never tried anything else in it, runs fine so no need to change

[Edbear]

Yeah I run a few extra pounds ...

Ive had my rear suspension taken up a couple of turns ...

Mmmmmm...

Yep Ed, she wallowed a little in the corners two up, particularly if uneven surface, now its far nicer ride, better control and one up it handles just brilliantly..

Likewise. I cranked my M50 up to the max a fortnight ago. Seems to be tighter in corners and doesn't buck over bumps any more than on medium, so I'll probably keep it there.

Regards fuel, I run 91 which is above the recommended minimum. Anything else would be a waste of money in the lowly tuned M50 motor, and as some have mentioned here and on other forums, higher octane doesn't help.

Oh! You meant the bike...

LOL!!! I've already insulted your poor Missus once! Figured I'd be in trouble if I did it again...!

Yeah mine says use 95 - but I am starting to think the same thing. The petrol companies make way too much out of us as it is!!

[P38]

I've only ever used 91 cos thats what the handbook reccomends. I get good mileage and theres always plenty of power on tap so havent even given a higher octane a second thought.

[MotoKuzzi]

The Guzzi manual says 95 min, never tried anything else. I was told that Gull 91 is imported from Singapore and more likely equal to our 96. I have been experimenting with tyre pressures mainly to soften the ride. Recomended is 33 front and 41 rear, it's highly manoeverable at that almost too much so but rides hard.

[Cave Cleaner]

I have tried 91. 96, and 98. Have found no difference in power at all. So stay with 91 most of the time. I get at least 170k on this small tank before hitting reserve.

You are not looking at apples with apples - or in this case MON vs RON ratings - there is a difference.

I always use the highest octane I can get 97.5 - but generally I try to keep with BP's 98.

Its not only the octane rating of this fuel - it has better additaves and burns better and cleaner.

Is ther any performance delivered for the bike - I dont know - but the cost difference is little and its going in my pride and joy - so I fill her up with the best pertol, oil, etc that I can buy.

Funny you should say that - I have a pig of a time finding a air pump station at a petrol station that can actually reach the rear tyre valve.....

I almost have to bend the damn thing off to get the thing to couple properly and inflate the tyres. This means long times between checks....

Any suggestions? Anyone used air compressors? If so any recommendations? The ones at Supacheap look exactly that - cheap!! the 3 on display were all broken!

There are right angle valve extensions available, where i'm not sure but have a look/ask around. I'm pretty sure the ones I saw were on 86GSXR's Daytona,

If it says 95, use 95. C'mon man dont quibble over a few cents, use the correct gas and have peace of mind.

+1 for me too pretty much.
