Branded v Supermarket fuel

We were talking about regular vs premium, not branded vs supermarket...

That was from a completely different thread di*k head.

It was a different thread yes, but it was still about branded vs supermarket, if you read other comments by Simon in this and that thread.

The brown is the half of the engine that ran basic EN228 specification fuel, Silver is using the Branded fuel with much more additives than the EN228 specification require.

No need to start name calling just because I quoted a couple of contradictory posts :)
 
I hope this tread doesn't get locked because of petty name calling because there is actually some quite interesting stuff being discussed in amongst it.

What I'd love to know, but probably never will, is if you were to have a sliding scale of 0 to 100 with EN228 minimum spec fuel at 0 and the very best premium fuel (whether that be V-Power, Ultimate etc.) on the general market at 100. Where would regular branded and supermarket fuels sit?

Also, while EN228 exists as a minimum specification, is it actually something you would ever buy as a regular punter filling up at Asda or Tesco? If not then that does throw a different light on the S4 engine demonstration.
 

The delusion is strong in this one.

He's asking about filling up an Auris? It wont make any difference at all wherever he fills it up. But as far as I can see you posted 2 rubbish quality images which showed very little.

Fact based source to back that up please. Asking as an Auris owner, on which the hybrid engines run on supermarket fuels are liable to have EGR issues at high mileages.

OPs isn't a hybrid. Helpfully pointing that out as I doubt you read that bit of the thread.

Nope. You can only Copyright creative works. Chemical and mathematical formulae are not included.

You'd have to patent the chemical process.
 
You show yours, then I'll show mine.

In the meantime ... Simon posted some good pictures.

He posted some awful images that show nothing really. Also I am not the one claiming supermarket fuel caused the specific issue you are claiming. A large proportion of cars on the road are filled using supermarket fuels, so you will surely be able to back up your claim with fact based evidence?

I made no specific claims. This was made first, so back it up with facts please and stop trying to use distraction techniques :

Simon working in the petrochemical industry could be classed as an expert, so holding you to a higher standards haveing rejected his knowledge should be enlightening for the entire subforum.
 
Just want to make a point so just ignore me if it’s not worthy.

Bp or Shell doesn’t matter specifically sell “standard” and “premium” fuel, which let’s take it as a known fact, Is much better for your engine but cost money to develop hence the higher price per litre.
Why bother selling “standard” fuel at all if you know for sure it’s not good for an engine over the long term? Why not instead, only sell “premium” and use the increased revenue for the premium product to offset the cost of R&D and therefore reduce cost to the consumer?

I mean they don’t after all put a warning sticker on the pump advertising to those less knowledgeable or perhaps ignorant, that you are using fuel that will without a doubt cause premature failure or excessive, avoidable wear and tear on your engine.

@Simon Does EN spec specifiy a min/max stoichiometry for fuels?
Good vid, shows minimum requirements vs what you can get.

Nothing on that, oxygenates and oxygen content maximums are stated which obviously impacts the stoich ratio of the fuel.
In the specs 'Super' fuels just need to be min 97 RON vs 95 RON of regular, this is the only legislated difference.
