This is what cheap(regular blend) fuel does inside your engine

Even the VP of FES (flat earth Soc) Poots got it right with the air/fuel ratio creating soot.
 
As for the FES... You can't handle the truth.

Act like a baby and sleep like one I suppose...

If you have any trouble falling off try counting your carbon credits.

Nighty - nite Poots!

Can you give exact specifications to support these claims?

..NO..BUT I'M SURE YOU CAN...

..i know, from years of experiments, as well as experience, that every one of my scoots run better...tank to tank, if i burn "premium unleaded" gasoline...

Unicorns dont poop, thats why theyre so hard to track.

I do agree with both point,i take your word on the kymco figures cos i havent looked myself....

Now we are getting somewhere.

This is better - you personally consider "best grade" fuel to be fuel with "highest octane number."
I also realize that for some personal reason you do not like "supermarket" fuels.

Two questions for you:

1. Do you agree or disagree with the fact that additional octane value of fuel above that specified by the vehicle manufacturer has no benefit at all?
I think that for most Kymcos that value is 91 or 95 RON.
We have not had fuels lower than 95 RON for a decade or so in my country.

Im in Scotland, our basic fuel is 95ron, fuel+ is 97ron but some fuels offered can be 99ron. I stick with the 97.

I have a quick question- if 95-97 ron (european designation) equates more or less to 91-93 aki (US designation), then isn't this the same fuel rating? ( I didn't look at the video because my sound card crapped out.)

95 RON = 90-91 AKI
97 RON = 92-93 AKI

There is much more to "fuel rating" than octane number.

That is the main online/forums fuel issue. Most people hear only about "more is better" and when they couple that with "I paid more for it, therefore it must be better", we have all sorts of bs on online forums when fuel quality is the topic.

There are dozens of parameters, additives and characteristics of fuels, other than octane number. Most of them can be seen in the catalogue of fuels I have posted, from purity, water content, burn energy, ethanol content to anti-knocking/lubrification/anti-freezing agents composition...

[jprestonian]

Yeah, but there's no telling some people. I refuse to be this guy.

Now your confusing the issue. In BASIC terms more is better... It's the things they leave in fuel that is at the center of the debate.
Lets say I tried to run a pure/clean fuel of 200 octane. It would NOT ignite with a scooter ignition system. So more is worse here.
Running 70 octane will ignite from the compression alone so it has uncontrollable characteristics that wont work in a scoot either.
The crux of MY belief/statements is: use the fuel that burns the CLEANEST, and is of an octane rating that gives the BEST performance, and leaves the LEAST residue. In the US we only have BAD, BETTER, and Not as good as I would like but ok.
Our 87 oct is for burning trash in the yard, or a stock scoot. Mid grade is fine for almost everything on the road. Hi test is the least I can run on without issues related to fuel. Since it works in my performance scoot I use it in EVERYTHING.
Also since I work on engines every day I sure don't want to go home, and work on one because of dirty fuel or Ethanol related problems.

I LOVE the Unicorn tracking bit!!!

Well, if Snopes.com ever gets bored, they have a lot to work with, here. 'S'all I'm sayin'.

I'll take a look at snopes to see what you meant. On a related issue... Anyone wanna buy some comic strips from me? I take Pay pal. Here's a sample link         this guy       Damn! That's not a link. I've been hoodwinked AGAIN!  Double drat that evil Jpres. My new arch Nemesis. Now I have to hire a Captain...

High octane to prevent detonation or knocking. If your engine stops detonation when using 90 octane , then that's the fuel for you. Anything higher will not result to better performance. Just more money spent. Higher compression engines need higher octane because they knock when lower octane is used and won't achieve maximum power.

That's the whole discussion in a nut shell. The only un addressed part is the residue left from lessor quality fuel. Here at least less octane is synonymous with lessor quality (more residue) overall. That may be what is creating controversy on such a simple topic. That being said I always recommend Hi test to avoid all the explaining what/why/blah blah blah.
Axy stated he tried using premium for three tanks, and saw no difference. Everyone I know that has tried it HAS seen a difference in mileage/performance. MUST be wWitches... That's the only logical explanation because all the Unicorns are owned by Bill Gates, and he wont share with us.

You're right sir, and why do people blabber a lot on octane? Other factors that affect fuel performance include vapor pressure, specific gravity, oxidation stability, brand, etc., etc. For example, a premium high octane that has poor oxidation stability will leave gum in your system and will surely affect performance.
