Its popular at my new local Shell, every day I see folk putting it in their std cars and when questioned they haven't a clue.
You question random people about their choice of fuel? That's..... uh..... different? Today I questioned a plasterer as he was about to put fancy fuel in his van.
He thanked me saying he was still half asleep and moved to another pump.
I have the opposite problem, local garage (an Esso) has been removing 'normal' diesel from half of its pumps during a refurbishment, it has 4 pumps, 2 on the right sell unleaded, premium unleaded & premium diesel, 2 on the left sell unleaded, premium unleaded, & normal diesel. It just looks like a really stty tactic to try an sell their fancy diesel (which is probably their least popular fuel), especially considering the pumps on the right side are much easier access to trucks, they are probably banking on people pulling up and not bothering to reverse back out to go around the other side (like I did the first time I came in there). I refuse to pay 138p/litre for fancy diesel in my X reg off roader . (normal was 112p)

Amazing that people don't realize that more octane = more bang and less required on the go faster pedal. Its not much but does make a difference.
Amazing that more people don't realise that only applies if the car is set up to take advantage of it. Unless there's some way of knock sensing, to change the mapping according to the fuel in use - or if it can't use 95 - then it will make absolutely zero difference.poing said:
They tested a few performance cars but I think it was the BMW M5 that kept the same bhp no matter the fuel due to a clever ECU.

So there we go - that'll change map to adjust to the fuel. It's one of the few that will.
It's increasingly common; certainly anything with VAG's TFSI/TSI lump in will. We have one car that does and one that doesn't so I run the Lotus on Asda's finest 95RON and the Skoda on Shell Optimax.

More octane doesn't result in more "bang" all UK petrol on sale has the same energy value.
It actually results in (slightly) less "bang". More octane means less actual fuel. TooMany2cvs said:

I'd be annoyed if the two Texaco garages near me stopped selling Super Unleaded.
I believe they are (or at least were) one of the few petrol companies that use little to no ethanol in their premium fuel
Nope. They get the same E5 from the same regional distribution depots who got it from the same refineries down the same pipelines. Then they tipped their own bucket of jollop into the tanker.I believe they are (or at least were) one of the few petrol companies that use little to no ethanol in their premium fuel

compared to the 5% (soon to be 10%) used by the rest.
If/when it comes to pumps here, E10 - which has been available on the continent for the thick end of a decade, and is the default in the US - will still have to be clearly labelled as such, and E5 will remain the default.TooMany2cvs said:

Not a big deal to 99% of people, but quite important if you have a classic car or a motorcycle with a plastic fuel tank, like me
Plastic tanks are just fine on E10+. There can be problems with some rubber pipes etc, but not with plastic tanks. Unless you think every single plastic five litre emergency fuel can is also at risk from ethanol...?Personally, if I had rubber fuel components that weren't up to the vast vast majority of fuel available... I'd replace the components. Oh, wait. I have. Including the fuel pump diaphragm in a now-two-year-old Stihl strimmer. Twice.
With regards to rubber hoses; it isn't easy/cheap finding/replacing all of the fuel hoses/carb internals on two 80's TVRs, two Italian motorbikes and a pre-war racer....

And as for lambda sensors - everything petrol since 1992 has had one of them...
No lambda sensors on my 1999 FireBlade, it runs on carbs. Doesn't run well on 95 fuel either.Edited by TooMany2cvs on Thursday 8th December 08:58
To be fair you should count yourself lucky when you have a petrol station like the one where I live.
Petrol is 118.9
Diesel 120.9
Super 145.9
But usually they never have any super, or unleaded or diesel, usually you pull up to all the the pumps bagged off and sign with "fuel tomorrow", what this means is they will get some fuel in the next week, but the fuel tomorrow will be about 200 litres of petrol and diesel.
It's not even like it isn't a busy petrol station, it is always busy they just don't pay their bills for fuel so now have to pay up front for it.
If they do have fuel though, they're still a pain as the guys behind the counter are always on the phone, get off the fking phone you ride , what is this current trend in smaller owned franchised stores, where the guy has to be taking to their mate and not serving?
I'd happily drop super unleaded from my local if we could get rid of the useless bds in charge.

The awkward configuration will be down to tanks and pump mapping.They will have swapped a single tank over, as it's cheap to do, digging up the forecourt to re map lines is difficult and expensive.

I don't know why it doesn't run well on normal fuel, but when the throttle is closed and then opened again at high revs it really hesitates unless it's on the good stuff. Maybe premium fuel has a better detergent pack and keeps the carb needles cleaner? Just guessing, really. Wouldn't expect it to be affected by the octane content which as you've pointed out is purely for knock control
