hi octane unleaded

[Lou Girardin]

All this talk of 91, 95, 96 and 98 - when are they going to bring out some up to date fuels? How about an 05? Or maybe a vintage - I think 72 was pretty good.

The '73 was a fine year, but the vine yield was very small so sales were restricted on weekends. But it was a precocious little number with a distinctive nose.

I've never owned a bike that came with a manual

Bikes come with manuals?

[Mental Trousers]

These manual things are only theoretical right?

Because the Yuroppeans, bless their little petrol soaked socks, make quite a few cars, of which they are rather proud, which definately do require high octane.

The Alfatoy VERY explicitly says to use no less than 95 RON, with a recommendation of 100 RON. The Alfaisti would probably bring down the Eytalian government (well, at least reduce its term from three days to one) if the petrol companies were to decline to supply a petrol suitable for the Alfa, and Ferrari and Maserati and all the other beautiful , contrary beasts.

And the not-so-beautiful, contrary beasts, like the Fart Punto, which was ugly till I threw the plasticky hubcaps in the bin and put Croma alloys on.
And the other contrary Urpeen cars, like our two Peugeots. I'm sure the 306 runs on high octane only, but it must've been on a sticker in the filler, which is no longer there since they changed the whole filler thing (for free) so the car didn't explode into flames. Or to stop people stealing fumes. Or summat. (They didn't say why they recalled it).
And the 205 GTi definitely hates lesser distillates, specifying in the workshop Manuel that top shelf stuff must be imbibed.
Number 2 Son ignored that, so I had to change the plugs and put some cough mixture in the tank.
It's easy, really: we all just need to listen to SWMBO, who recently proclaimed that "All our vehicles (4) are to be run on Ultimate and nothing else."
"Errr.... I had to put Gull 96 in it yesterday, Dear, as there were no purveyors of Ultimate adjacent to any of my expeditions. But it's REEEEAAAALLLY good stuff. Honest..."

Bloody brilliant. Thank you.

Octane alone will not increase power. It only allows the potential for an engine to run a high compression ratio - and that’s what will increase power.Run a high compression engine on low octane fuel and detonation will occcur - and that can destroy a motor.

It's been report that this 98 octane, on TV even, is causing excesive nocking and to adjust your ignition timing accordingly. Why?

And yeah and I agree 91 does the trickalright and has saved quite a substantial amount over the years

That's highly unlikely. The point of higher-octane petrol is to minimise knocking in engines that run at high compression ratios and/or advanced ignition timing.
Perhaps it's more likely that people have been sucked in by the "Cleaner! Faster! Bigger! Wetter! More Poweful! Greener! Expensiver!" campaign, and have been putting it in their low-compression, spark-retarded shitboxes expecting 1700bhp, and instead the aforementioned low-compression, spark-retarded poor excuses for engines are having trouble getting the fuel mix to ignite.
It certainly does take more to light up 98 in cold weather on the VifFerraRi than in warm weather, but conversely it knocks less when the engine's running at 106 degrees and the fuel level in the tank's low and the fuel pump is running hot and turning the warm petrol into fumes.

IT WAS ON TV!!!!!!!!! With some specialish mechanic stating the ingintion timing needed changing. Can remember a conversation with a mate about it saying it was bunk as you say. Honest Indian.

I accept that it was on TV, but don't believe everything you see in the media. They are generally a pack of F'wits.

Ok I know it was a while ago, and maybe I should let it go, but with the Y2K "problem" they quoted a person on the front page of the herald spouting bullshit about computers and his qualification was (and I quote) "a frequent internet user"

Then in the next breath when the world didn't in fact end the media are slamming all the hype.

Generally the more you advance (fire the spark plug before the piston reaches top dead centre) the ignition timing the more power you will pull out of an engine. UP TO A POINT!

In theory running 98 could allow you to run some additional advance, but it would not be necessary to.
