Branded v Supermarket fuel

If oil burns it goes down the exhaust, not the inlet valves.
The point here is regardless of the cause, the fuel has an impact on mitigating the impact of these deposits.
Nope it can build up on the back of the intake valves in direct injected engines. That's part of the reason many went back to using port injection as well.
Agree it is an impact, but blowby will cause these deposits anyway, regardless of oil consumption levels.
The point is in the same tests with same factors the fuel makes a difference, now i understand you always want to change the topic or tweak it about something irrelevant. But this is a test Shell have used to demonstrate, in a fair test which only looks at fuel impact, it is fact based. I'm sure you will yet again impart your opinion.
The VW issue is more due to unburnt oil / vapours being returned to the intake side of the engine via the PCV system, rather than burnt oil, as I understand. Once you have these vapours on the intake side, with no port injection there is little/nothing to stop it building up on the back of the inlet valves and no amount of good fuel is going to stop that specific issue.
The root cause of the real problem engines though is the amount of unburnt oil / vapours that actually get fed back via the PCV in the first place.

Yes you are right. Oil companies ONLY make money selling fuel.
Seriously mate, you need to reflect on some of your posts. These are engineers/chemists doing their jobs running tests to improve fuels, going to work to try and improve things. There is no hidden agenda. I don't understand why you comment on literally anything with such a naivety and basic understanding of the subject. Your name always pops in thread with these, followed by one liners that are so wrong and I hate reading incorrect information all the time, knowing that other people read it and think it is correct. This was the purpose of me sharing some information on the limits of what i am allowed. However you seem to take it as an opportunity to pick out 1 or 2 things to argue with. I have no interest is spending my time arguing with you on here anymore. Its just filling the thread with drivel
Going to back to my post. The problem you have is not convincing some those who are into cars about the benefits, it’s those that couldn’t care less. My girlfriend, couldn’t care less, the mum taking her kids to school, couldn’t care less, The person on rentage scheme, pcp or the like who gives the car back after a few years, couldn’t care less, the owner of a business with multiple vehicles doing higher than average mileage who’s fuel expenditure makes up a large percentage on their revenue, couldn’t care less. All those types of people see is the 4p difference and that’s it.
Winning arguments and imparting your expertise on a pc forum will do very little in the wider world. Now like I said if the average person at the pump didn’t see a 4p difference between standard and premium, they would choose premium, would they not?
Your marketing team need to do more it would seem.
Ok selling fuel and selling oil lol.
If it's such a neutral position why does every oil company have their own researchers and claim their stuff is the best? The fact there are so many different research teams and so many different mixes means no one really knows what the best is

Exactly
I'm not here to sell it. Was just trying to inform those interested.
You are exactly right about other people's attitude, hence they run ditch finder tyres, never change the oil etc etc. Sometimes you have to pick you battles. I will imagine that a lot of other people chose the petrol station based on price, convenience and probably the shop attached to it. People who are interested may want to pay a bit more. Such is consumer behaviour.

Which is funny as Shell around here varies in price a lot, in fact it's similarly (sometimes cheaper) priced than other options, such as BP, Tesco etc. for both regular and super unleaded. So Shell isn't all about selling expensive fuel now really is it.
Because, like the automotive industry they see value in doing it, investing huge amounts of money into research into improving the world? (for whatever reason, OEM technical challenges, national interests, morals or emissions legislation). Otherwise we would all still be driving cars, guzzling fuel and pumping lead, NOx and PM into the atmosphere. The world doesn't sit still and if you spend some time you would see that actually the premium fuels target slightly different audiences with different claims.
If they were that serious and it made that much of a difference they wouldn’t sell “standard” fuel full stop.
Stop messing about and use the extra revenue generated to offset the r&d and reduce the price at the pump. Job done. Otherwise you’ll just keep getting people thinking it’s nothing but greedy oil companies attempting to grab more cash.

I think you have missed the point, if you want to do that you can sell a commodity with no premium and its a fight to the bottom. Not that production costs are a significant part of UK fuel pump price
By being ahead, you can sell the old technology to other people who just want basic...
No one is holding anyone to ransom here, its a choice we all have! Petrolheads are happy to pay more.

@Simon you're far more patient than you need to be. You've given a load of information for people that are interested and clearly some just don't want to listen. Thanks for providing the useful info though, even with the less useful people posting.
Why else do companies exist? It might be interesting to see what your pension is invested in
Seriously guys, you are on a computer forum about overclocking and paying massive prices for 'a computer' that hardly anyone else will understand. And you are saying that you are surprised companies make money. You are using a forum that is paid for by the profits of people buying computer parts. Parts that customers are happily paying a premium for?
Why cant they all just sell the same stuff and not invest? The answer would be that we would be still sat here on 486 DX2 66s.

Thanks - appreciate it, this lockdown is giving me more time that i would usually be about on here. I'm off to research M3 mods and paying for stuff i don't need but i want to pay extra for
