Works well at clearing the gunk from older vehicles, pretty useless if you generally use fuel with additives or have a newish vehicle - though you do notice a smoother drive & better fuel consumption

Even more pointless than the Redex system cleaner that's been posted here …Even more pointless than the Redex system cleaner that's been posted here a few times recently.Almost all petrol engined cars in the UK are optimised for an octane rating of 95, ie the level of regular petrol. There is a misconception that increasing the octane rating with additives like this will improve power output. It doesn't.So unless you car is optimised for higher octane fuel, this is a waste of money. Even at 90p.

Rang my local superstore and it's £3....so guess it's not national ;-(
Not worth the money anyway

Bought it in Tesco on Thursday for £2 (idk why lol), national deal. Petrol version also available although not on their site for some reason. Great price O/P, beats the Tesco deal so have some heat.

Can anyone explain why to use this?

Edit, never mind, thanks luvsadeal

So you notice a smoother drive & better fuel consumption, but you find those qualities useless????

That is wholly incorrect: modern engines are calibrated to run on RON99 fuel to give the best possible ECDC calibration test results. So if you run them on an inferior fuel you will inevitably get inferior performance, inferior economy and increased CO2 output.

well, you're just paying for those benefits, not bad @ 90p (45p/ tank) though more generally you'll pay more - but you might as well just pay extra for fuel with additives in

personally I just use supermarket fuel then every 4th or 5th tank use Redex or the premium fuels to clean up the fuel injectors etc
I put wyns extreme clean in my diesel only a few weeks ago. Best fiver I ever spent! Smoother acceleration. Better fuel consumption (about 5%). Car just feels newer. I’m putting it (or redex) in every 3000 miles from now on. With the improved fuel evening even if I pay as much as £5 I get it back after two tanks of petrol.
The ECU adapts to different octane levels automatically based on the ECU map, Since European cars are generally mapped to run at certain octane levels found across the European market. When you have your car remapped you will find that it will perform very well in this Country where quality and octane levels are good however in other countries it wouldn't perform very well at all as it's programmed to run on better quality fuel etc. Remapping optimises the performance. Redex will genuinely help remove carbon deposits and clean the injector system to a certain extent, how well is negligible so theoretically it can help restore power. Not increase it. It's rather sad and should be against advertising rules that it's implied it's a "booster". Cars are limited by there maps and unless optimised via remap to take advantage then you'll never increase power over standard map stored in the ECU.

Totally wrong.
modern cars run best on 98/99 octane fuel. The ignition timing is slightly retarded by the ECU when 95 octane is used. That means that the spark plug does not fire at the optimum time in the piston stroke, thus the car is not running at its optimum performance.
This is all controlled by the ECU.
if you add a booster like this, it stops the need for the ECU to retard the ignition and the car runs at the best possible efficiency/performance.
Its a flip of a coin money wise. Do you buy cheap supermarket fuel and then add this Redex booster to increase the octane rating and add cleaners........or do you just buy premium fuel such as Shell Optimax or BP Ultimate? These do the exact same thing.
Cost wise, I reckon its gonna be similar.
VRRROOOOOOOOOOOOOOO
1 The video from Fifth Gear
The system cleaner (not the product in the OP) gives a one time boost in the older car. As the presenter makes clear, you're wasting your money using the system cleaner every fill. The Fifth Gear report is journalism rather than a rigorous controlled test. The manufacturer presents no evidence on their website for the product's effectiveness. If it really works, you would think they would be keener to demonstrate it. Even anti-ageing face creams provide some justification for their claimed performance.

2 Engines calibrated to run on RON99
From Toyota Avensis manual: "For optimum engine performance, select unleaded gasoline with a Research Octane Number of 95 or higher."
From VW website "For most vehicles standard unleaded is fine (95RON) but for GTI and 'R we recommend super unleaded (98RON)"

3 A smoother drive & better fuel consumption...
The product in the OP is an octane booster. Octane rating measures how much the fuel and air mixture can be compressed before it ignites. Fuel consumption and power output are a result of the amount of combustible hydrocarbon in the fuel. An octane booster does not of itself increase the amount of hydrocarbon.
Love it.

It's obvious: always buy super unleaded, preferably V-Power, with a cashback credit card and the Drivers Club discount to peg back the 7% premium over standard fuel.

Experts or drivers expereincing the benefits of using super unleaded?
I saw this earlier today in Asda BOX of 3 bottles for £4.50!

Wasn't sure how good it is to use in my trusty 170k 1.9TDI Polo though!

Well I wouldn’t use this one as it’s for petrol and you have a diesel car
Doubt this will be in my local boring Asda as none of these deals are , especially the Xbox games . It's Bournemouth Castlepoint in case any top dogs in the company are reading

This is Petrol booster mate, not system cleaner.
I have to put super unleaded in mine or I lose 10% of power. Apparently according to forums who have asked VW. If I get normal unleaded and put this in. Would it give the same affect but cheaper? I've got a golf R

Probably not. According to the manufacturer website, this boosts octane number by 'up to 1.5'. Regular petrol at 95 + 1.5 = 96.5. VW recommend 98 for your Golf R.

If your car is clean already. Then it wont make an already clean engine any cleaner.

Many thanks for the advice.
As my car is 10years old I think I'll just keep buying the occasional bottle, as I regularly see it reduced. Cheers
Thanks OP I just use regular fuel from anywhere then every 500 miles put a 1/4 tank of Super Unleaded.
I used to drive diesels due to the amount of mileage I used to do.
The one thing I would always do with diesels was once a year put in a bottle of Forte Advanced Formula Diesel treatment just before I set of on one of my longer runs 100-400 miles and once the engine and everything else was hot and the speed was up to a (Reasonable) rate I would frequently see the odd cloud of smoke in the rear view mirror as I headed down the A/M74,
Forte is pricey but well known in the motor trade especially useful just before a MOT.

Welcome
Save your money and save up for BG244 an do it every 6 monhts.
Heat for older cars, but definitely regional. It's £9 in Asda near me!
