s2r  1000 run 98 why stops surging at low revs and gains 40 kays to a tank

[Two dogs]

Hmm this is an interesting thread , the dealer where I purchase my bike told me to use the lower octane standard un leaded
but stressed to never !!! use SHELL as it contains to much benzine (fouls the plugs)same with BP unless really no other option when running out.
Any one else heard this ?

[Betty]

When we picked up our ikes we were told to never use the Shell 98 - at that time known as Optimax I think ... don't know if the change to V-Power relates to a change in composition though?

We were told to use 95, 91 if you have gone bush and have no other option.

For completeness: somebody posted (on the DML I think) that they received a response from Ducati Australia telling them not to use ethanol blends.

Won't be long now before Big T and Ellingly roll out their spreadsheets and give you all sorts fuel economy type data too

Have 2005 Monster 1000s.  Use Shell Vpower cos I live in the country and can't get anything else better and it runs fine.  Do heaps of country miles.  Ride in Melbourne often (after doing the country miles).

Bike likes Mobil Premium unleaded when I can get it. Doesn't mind Vortex.  Hates BP Ultimate or any 91 octane fuel (runs very sluggish).

Have been told by 2 different dealers never, ever to use petrol with Ethanol in it. Haven't had any plug problems. Because of the country riding I suppose.

I also read about using 91 - 95 in the 2 valve monsters, then 1 day I suffered brainfade and put in a tank of BP ultimate, and did that from then on (seemed like a good Idea at the time), recently switched back to to normal 91 and have found the bike seems to prefer it.
The bike feels to be much better all round when running the 91, so I'll stick with it.

read your owners manual  

yeh i read the owners manual.. which said 95.
but from what most people have said, looks like 91 is the better option when hanging around town so i think i'll stick to that.

For completeness: somebody posted (on the DML I think) that they received a response from Ducati Australia telling them not to use ethanol blends.

Yep, that was me.

There is a listing of manufacturers/vehicles on the Federal Chamber of Automotive Industries (?) website, the list saying whether those vehicles could/could not use the ethanol blend. Ducati was not on that list so I informed NFI about it and I also asked them if Duc's are suitable to use the e5/e10 blend. And NO was the answer. They didn't know that they were not on the FCAI list and were going to fix it.

As of last week, they are still not on that list.  

And there is news that ethanol blend is being rolled out to more service stations, replacing regular unleaded. The BP around the corner from my joint does NOT have regular unleaded!  

And I heard with the Shell 98 is that it has too much detergents in it, which supposedly 'cleans' your engine as you drive/ride it.  

Ah, I use 91. Everything else f*cks my plugs.

He said he read his owners manual you goose!   






 

[dragonworld.]

Mmmmmm, nuthin' worse than a F#*%$d plug ??

Mmmmmm, nuthin' worse than a F#*%$d plug ?? 

soo... whats a f###'d plug? something to do with the spark plug i assume? and how do you know if its f'd? and what do you do when you realise its f'd?

[bazz20]

yes i know super , but if your manual says 95 run 95 if it wont run 95 you have two other issues , low compression or fueling problems , the octane rating is to do with compression ratios , the higher the ratio the higher the octane needed

[Six95]

I've only ever used 98 and when it's not available I use 95. Runs perfectly fine, does not miss a beat
My manual says 95+, so that's what I am following.

Well, when I purchased my bike back in 2005, I read the manual, and it did say 95. I asked the blokes at Frasers in Sydney & they all said, don't run 95, only use 91, 95 will foul your plugs. And where I get my bike serviced at Gowanlochs, they all say use 91.

That manual is printed for the European market and the fuel they use there is of a lower quality than the fuel we use here.

If you've tweaked with your engine, fine, you may need to use a higher octane. I don't think I had low compression when I brought my bike new.

You'll know, it just happened to me when I ran 95 in it because nothing else was available.

It doesn't idle well, it jerks, backfires, hesitates and stops running.

[bazz20]

im not going to argue with you super but go with what works best but a lot of problem stems from set up, our ducati dealer asks what type of fuel you want to run and tune to that fuel , as for fuel   European fuel is far better than anything we have here , like i said if your having problems it more to do with set up , by useing a lower octane fuel than you should causes pre ignition and pinging , and that my friend is not hear say thats fact , and im not having a go at you super im just pointing my view as a wrench and the fact all the fi bikes around here run fine on 95 -98
