Super Unleaded

[mrchips]

I filled the bike today with £10 of BT Ultimate Unleaded at 103.9 a litre just to see if it would make any difference. I didn't really notice much difference, except to my wallet.

That's why I always fill up with the 93p stuff from Asda/Morrisons etc...

I always use super and I dont care who you are I can tell when cheap fuel has been put in my bike.

From smell and the way it runs

Its pronounced Jixxer!

doesn't that super stuff bugger some bikes? , something to do with the octane rating and knocking/ self ignition under pressure?

I know on high performance cars the higher octane makes a quite substantial difference but not sure about how it would effect a 60bhp bike.

Hi

Higher octane rating will not bugger the engine up (certainly not the tiny extra from super unleaded), but will on its own not give any more power at all.

Normally it will loose a tiny amount of power (insignificient with super unleaded, although start using avgas and you would really notice it).

All the best

When EVO tested the fuel on a standard Golf GTI, the super unleaded BP stuff produced an extra 15 hp over the supermarket cheap stuff on the dyno, and an extra 24 lb/ft of torque. It DOES make a difference. They also tested it on a BMW M5 and found that the beemer produced an extra 45 hp on the posh stuff, but torque remained the same. They were also fans of the new tesco 99 octane stuff.

Mcgee will experience a larger difference as American fuel ranges from 87 - 95 octane.

The 10p I'm saving, saves me a £1-ish when I fill tank up fully.

Every ten times I fill up, I save a £10er+, not bad eh .

I put normal unleaded in my bike last week. Since i've played with the compression and squish it's only been run on super.

It didn't like it at all. Stutter stutter splutter.

don;t cars and £££££ bikes have octane sensors on them to adjust the engine a little anyway?

Don't we go over this every other month?

Well, the Golf was producing 200 hp on the dyno with the worst fuel. The test was carried out 50 times for each fuel on the same dyno for each car. Like it or not, that is what the difference averaged out at.

Does anyone know if a mid nineties MR2 Turbo has a clever enough ECU to work better with super?

The Super unleaded only benefits you if your engine runs a high compression ratio, I think its more psychological than anything else, you expect your bike to go faster because you have forked out, and as such you either ride it harder or dillude yourself into thinking it does...

Saying that maybe nice shiny bikes like litre gixxers/r1's would benefit, my 500 sure as hell doesent

As others have said, if your bike runs fine on 95 ron, it will not gain any power from super unleaded. Contrary to what seems popular belief super unleaded is not more explosive, it just lifts the threshold for knocking. The only road car i have seen that needs to be run on super is my uncles homologation edition M3 GT2. The compression is too high to run on 95. Ive been in the car before when we were driving back from a Boro match. He ran out of fuel and had to fill up with 95 above like 2k it would knock and ping all over the place.

I used Super Unleaded for a bit and didn't notice any difference at all, except for the price. No difference in MPG or anything.

I was recommended to use it because of the better cleaning agents in it, though. Is this true?

[DucatiEVO]

I use super in everything (unless it's not on sale where I'm filling up). If I use normal unleaded everything feels 'flat', on super everything just feels a bit more responsive, not necessarily more powerful/faster.

Just my two cents.

I do believe I saw a program (possibly 5th gear) where they tested a golf GTI, some normal hatchback, and an impreza. I remember it mostly because the dyno wasnt a rolling road, it bolted to the hubs?!?

Anyway i think the golf did make a suspiciously large gain in power, I suppose it could be a relatively decent gain if its retarded right back on 95 RON...who knows

Anyone who says Tesco/Morrisons is as good as BP ultimate unleaded etc is daft.
