Branded v Supermarket fuel

The design of the engine itself is a much bigger cause. If oil consumption is high then it's likely there will be bad buildup as well.

All meet the UK fuel spec of EN590 or EN228 so you are right if I have incorrectly made out they are all bad. And compared to other parts of the work the UK fuel is very good.

So if I'm following all this right, you're argument is that petrol sold at chain/franchised petrol stations (BP/ESSO/Texaco/Shell/etc) is good because it it will meet and most likely surpass the EN228 standards (albeit we have no way of knowing how much by), but petrol from supermarkets and independent petrol stations is not as good because it will also meet and most likely surpass the EN228 standards, but you say the magic juice in yours is better.

And to prove this point you've shown us a publicity stunt your company did where you ran half of a V config engine on your fuel and the other half on fuel that matches the EN228 spec and no more, and achieved better results on your fuel. Yet you've conveniently left out the fact that petrol stations in this country don't really sell petrol that "just" matches the EN228 spec >.>

Now granted I don't have the science background you do but I did work at an independent petrol station during college so I do know how the ordering process works. Oh, out of interest what's your opinion on Sainsburys fuel? :P
 
I’m trying to not get into an argument about this but you literally have no idea in what’s involved in developing fuel.

But yes the minimum standards are just that. Why do you think supermarket fuel is often much cheaper? Sure it’s maybe a loss leader but they make no differentiate product offer. It could be that they are putting in the absolute minimum required, I cannot comment any further than this here.

You won’t find anyone I work with out supermarket fuel in their own cars. And it’s nothing to do with brand loyalty. Same with people who develop fuel injectors.

But obviously people are free to do what they want and use what they want. I’m was trying to highlight the difference.

The car wasn’t really a publicity stunt to start with, it was just a test mule bought second hand to try a real life test. It ended up working much better that expected. And as it was the new generation of fuel so ended up being used as a launch demonstration. Anyway those pics are from Geneva 2017 now so things are always evolving.
 
Is this just an issue with petrol? I’ve had three brand new cars in a row, all diesel, all gone back at four years old with roughly 125k on the clock and I’ve always used supermarket fuel and never had a fuel related issue. Is there less of a difference between premium diesel and supermarket stuff?

All the fuel is the same, it all comes from the same refineries the only difference is any additives. All fuel in the UK has to meet strict standards anyway, this idea there is a vast difference between them all is laughable.

Sure. What makes you think the UK standards are 'strict'? What requirement exactly? I'd be interested to know your views being as hundreds of people work to develop fuel around the world.

So all the fuel in the UK is of the same standard, it all comes from the same refineries and the only difference is the additives. So your argument is what exactly?

All food meets the same standards, you telling me it all tastes the same?

Of course the additives in the UK are different, they make all the difference. Try using fuel without additives if you think they make no difference.

What is your background ?
 
I have to admit I’m struggling to believe I’ve just been lucky given the amount of fuel I go through. I’m genuinely interested though if there is a proven difference.
 
Well i tried to educate and that's all i can do. Seems the internet myths will continue about Fred the tanker driver.

Those pictures i shared, the ONLY difference is the additives...

I've just seen you work for BP? Not quite independent in this then.

Makes zero difference really. Shell and Exxon i would advocate the same benefits.

Not sure you noticed, this is a car forum and i thought with all the chat about modifications it would be worth highlighting the difference of the fuel used as we have a specific request from the OP. Not sure how your input is helping ?
