Congratulations on your first deal post too!
it's nearly this price for 1 bottle, great find, thanks
Love this stuff, takes me back to cherry bombs, K and N filters and hooning on a Sunday!
These appear to be small bottles.

It seems ridiculously cheap, and I'm suspicious of the "£50 per litre" figure underneath the price.

Amazon seems to suggest that "1 shot" is 125ml, and you are buying 4 "1 shot" bottles in this deal which makes it 500ml.
amazon.co.uk/RED…rch

Amazon is £6.96 for a single "4 shot" / 500ml bottle though so I guess this is still good value - the Wilko page just isn't that clear.

Edit. Halfords sells the same thing. These are only 90ml bottles, which makes it £12.50 per litre at Wilko vs £12.99 for a single litre bottle at Halfords.

2 shot or 2 full tanks is normal £2
Why bother with this when you can have use V-Power that has a complete package of additives that Redex alone does not provide?
3 for £2.25 at asda

That's 250ml x 3

You don't need a fuel that keeps the engine fuel system clear of hydrocarbon deposits, gives more torque at low rpm (if you use that to shift up earlier then you will be using less revs for the same performance and will enjoy an improvement in fuel economy) or gives more top end power?

I still cannot believe that you can get snake oil stuff like this, how does it still exist? A bottle of this mixed in to 40+L every few tanks isn't suddenly going to magically clear away thousands of litres worth of accumulated gum and baked on deposits. If it was so effective there would be marketing photos all over the internet, with before and after videos. Even something so basic as pulling out a spark plug and sticking a £10 USB inspection camera and showing the valves.

All you get is simulated chaff like this:

Using a premium fuel every fill up is a better and easier idea, if you feel the car justifies it and are that way inclined.

Those lab tests are amusing. Some years ago a friend who was involved in either those or similar was telling me stories of super low rolling resistance tyres, part filled diffs and the like. basically, anything that minimised drivetrain losses...

Of course, but we are talking about the fuel used (in this case V-Power). We know that advertised mpg figures are duff.

Nice idea - where's the proof? I have to agree that I would prefer premium fuel over snake oil like this but they certainly know how to charge for that premium!

Proof is within ASA legislation: V-Power has advertised benefits because if the benefits are advertised they have to be capable of substantiation or the ASA bans the ads. In addition, using a cashback credit card, maximising the Drivers Card results in a net cost benefit over regular fuel. It's a no-brainer.

There are also usual loads of people on HUKD that claim to be tanker drivers or know a tanker driver who claims that more expensive 'premium' petrol or diesel is no better than the standard stuff: that it's all the same and all comes out of the same tanks at the depot/refinery' or words to that effect. I suspect that these are supermarket tanker drivers who curiously don't tell you ithat they can be ordered to pick up fuel from all sorts of different depots. Maybe Shell or BP or Esso or whomever, but it is also why supermarkets cannot advertise the fuel economy, engine cleaning and emissions benefits of their fuels. But Shell or BP or Esso or whomever can.

I'm not going to disagree with you on the general points as I don't know and few people seem to. But if there was an overwhelming case for premium fuels would the suppliers not be shouting from the rooftops with hard facts supported by the financial case rather than some vague 'it's better' statements? I can accept the possibility that some additives may keep an engine a bit cleaner and this may have a marginal effect over very high mileages (but few people keep a new car for 100k plus anyway). It would have to be a pretty strong case to justify the premium price - I sense they can't make that case and just play to those who 'only buy the best'. Milk from Waitrose is just like milk from Aldi, except for the price.

In 30+ years with premium vehicle manufacturers (not dealers) the case for premium fuels was never made by our engineers. The handbook will tell you what they recommend and I don't think any of them suggests premium fuels (except where a high performance engine NEEDS higher octane petrol to function at its best). If the engine doesn't NEED higher octane (very few do) there is zero gain from using it. This is about performance, not cleaning, anyway.

What I will accept is that all modern fuels are much poorer than they were 30+ years ago. Leave modern fuels in your lawnmower, motorbike, etc. over the winter and it will deteriorate without additional stabilisers. It will also eat parts of the fuel system of older vehicles and as it's hygroscopic it will attract water which settles at the bottom of the tank and cause corrosion if it's made of steel.

Anyway, I and many people remain open to being convinced that we will save money with premium fuels but the case just doesn't seem to have been made.

Just searched for Shell's claims and found this:

shell.co.uk/mot…tml

It's remarkably fact free: the only number used is then negated in the small print: "3x more cleaning molecules does not result in 3x the cleaning power".

It's all marketing guff. I'd love it if they could say "gives you 5% better fuel consumption*" or similar, but they can't as the ASA would fall on them like a ton of bricks. Instead the small print finishes with "No guarantees provided".


* Or whatever it would have to be to cover the cost: what % more does the premium fuel cost? Shell is one of the better priced branded fuels but it's regular fuel is still usually at least 2p more than supermarkets where I am.

Oil firms already advertise their premium fuels and list all their benefits. As I mentioned earlier, all ECDC lab tests use V-Power for the specific reason that ECUs are programmed to run the engine with better quality fuels with higher RON.

Milk varies across supplying farms. There are more farms than refineries. Next you'll be suggesting organic milk is the same as standard milk...

Incorrect - just because you believe the car doesn't need a superfuel that has a higher RON, doesn't mean there's no gain from it. Superfuels have more cleaning properties that what Redex provides.

I have offered opinions and you have offered contradictory opinions - neither of us is offering measurable facts - in my view because the case for premium fuels cannot be supported rationally. Shell's glossy page on that link is a prime example - it's actually claim free! Offer proof and I'll not only accept your case I'll even move to the fuel which will save me money.

Because not everyone drives the same vehicle. Simple really.
Obvious this is an anecdote not data but my 12 year old Audi came up with emissions light on the dashboard. It didn’t go away for two weeks and my MOT was coming due. Figuring it was worth a punt, I emptied a bottle of this into my next full tank (ordinary stuff from Tesco) and 100 Miles later, the light was off and it passed its MOT.

As I say, just an anecdote but it worked for me.
