I used to periodically use redex on my old vehicle - which was not a performance car like my vRS. I've just done 4000 miles and already put another litre of oil in. Im just wondering if anyone uses redex... and would it be suitable for the 1.4 TSi. Im thinking that because I put 99 ron super unleaded in now it might already have all the necessary additives to keep everything clean.

Cheers

I'd say there is absolutely no benefit to putting it in such a new and modern engine running on premium fuel.

Nope - stick to 98 or 99 ron and that's enough.

Redex comes from an era prior to the additives in today's fuels. You wouldn't see any benefits from its use.

Good stuff. Thanks all.

Use BG 44 in petrol vehicles but put 10k on the car first then u use it only once every 10/12 k on the clock it's really is a magic potion

BG 44 ?

What new Dark Magic is this?

That's +1 on the BG44. Many on here will know modern fuels actually burn less clean than fuels of even 10 years ago. This is because modern engines operate at very very high temperatures to get the maximum fuel economy and power. Also the petrols and diesel we use now have changed too. The cleaners in modern fuels help but injectors, valves, pumps etc all develop a nasty crud and varnish on and in them altering and reducing the spray patterns for example of your injectors. It doesn't matter how you drive it or how the vehicle is used, it happens to every bodies car, petrol or diesel. It happens so slowly you don't notice it. Redex works fine (get DPF friendly for diesel if you have a DPF). If you haven't used it before and your car has covered a lot of miles your engine will run rough initially as the cleaner removes the small particles of gum and carbon and these pass harmlessly through your engine. It worth running two tankfuls through if you've never used it before. You will notice a difference, they work! Don't take my word for it, there's loads of stuff in the motor mags about how well they work.

Also If i may add which fuel companies never seem to want to talk much about but by law all fuels must now contain 5% of recycled material or known as bio Fuel's ill post this up for ye :

Under current legislation petrol can contain up to five per cent biofuel without the pump having to mention the percentage or warn the driver. This is because the mix is so low it's not thought to have a detrimental effect on the engine. Legislation is currently in place to guarantee the mix will be five per cent by April 2013 and almost all fuel already contains a small bio element.

Over the five per cent level and the pump must, by law, be labelled "Not suitable for all vehicles: consult vehicle manufacturer before use."

However, due to Europe's Renewable Energy Directive (RED) higher percentages of biofuel are on their way to the UK. RED requires members of the European Union to ensure that 10 per cent of energy used in road transport is from a renewable source by 2020. Interestingly, to reach a 10 per cent renewable energy figure, a 15 per cent mix of biofuel is required.

While this deadline is some way off, fuel companies are planning to introduce petrol with a 10 per cent bio-mix, known as E10, to the UK next year. BP is expected to be one of the first to offer the higher percentage biofuel.

To marry-up with the changes, the Department for Transport is currently considering downgrading the wording on biofuels so that only that with a greater than 10 per cent mix will have to be labelled with the words "This fuel contains more than 10 per cent biofuel."

A BP insider has likened the change to what happened when we swapped from leaded fuel to unleaded. And the reason only newer cars can run on E10 is because the higher ethanol content from has a corrosive effect on the seals and some alloy components in the fuel system. Modern engines have been built to withstand this.

While many brands, BMW among them, have declared their entire petrol engine ranges fine for E10 there are some exceptions, including 993 (and earlier) Porsche 911s. First generation FSI engines used in VW, Audi, SEAT and Skodas typically between 2000 and 2006 are not E10 compatible but all the group's current petrol engines are.

Cars like pre-2002 MX-5's and icons such as the Peugeot 205 GTI will also not be able to use the E10 fuel. Unlike the switch from leaded to unleaded petrol, there are (as yet) no fuel additives on offer to counter the issues around E10 either.

Drivers of older cars that won't take the E10 biofuel will have to seek out regular fuel, which is expected to become less common over time.

So im fairly sure this would leave a build up of **** in your engine

hopes this helps

I find it - and similar products - work in older cars... your Twincharger? Nah, doesn't need it!

The new fuel cleaners like BG have been developed with the new cars in mind the newer versions ie 244 and 44 are now the best additive available were I agree the redex is more in keeping with the older PD but as previously posted the new high level biofuels will be an issue for all vehicles new and new, I may run both the 1.4 tdi and crtdi 1.6 will be fed on vpower

I found an excellent use for Redex 20 years ago.

They used to make a version that you squirted directly in your carburettor (gosh does anyone remember carbs?) air intake for a couple of seconds. Allegedly it cleaned the carb and stuff, but the fascinating by-product was excellent and massive thick clouds of blue-white-smoke from the exhaust.

So a visit to a local scrapyard got me a micra washer bottle/pump/hose/squirty-jet. All fitted under the bonnet, the jet installed in the carburettor intake, the switch on the dash and the bottle filled with redex.

So then when you were being tailgated by Nova-guy (this was even pre Saxo-guy days) a flick of the switch made him disappear into thick blue-white fog!

The downside was more than 10 seconds use fouled the plugs and produced massive misfiring, and the £30 per minute cost in Redex of running the pump!

Wow, sounds a bit dangerous!! But very excellent

FWIW, some manufacturers include fuel system cleaner in their annual service schedules, for example Fiat's multijet diesel engines.

Redex is mostly Naptha. Its a strong solvent also used in basic injector cleaners and the like. Does it do any good ? Maybe, at worst you wasted a few quid. Maybe it keeps a diesels innards a bit cleaner than without it. I still bung a bit of redex in my motorbike,maybe its a placebo but I dont plan stripping the bike just to check.

Redex is superseded by the likes of BG44/244.This is mainly Polyether Amine. Unlike redex which 'may' do some good this stuff has a pretty damn good track record. Personally I would save my pennies,not use redex and bung in a tin of BG44/244 at service time.

Out of waranty of course

Actually, bio-fuel (ethanol) is alot cleaner then proper petrol when it's in it's regular form.

It's cleaner when it's combusted aswell, but we'll leave that subject for the moment.

The problem with it is that it "cleans" too well in some cases.

Take for instance an old car which is "built" for petrol-use.

The problems you see when you convert those is that old dirt/rubber/additives is stuck in the hoses.

The ethanol makes that come loose and clogs up fuel-filters / injectors and so on.

So all in all : additives is useless in most occasions.

I've never had to use it yet and i've driven both old overcharged engines, new overcharged engines and old naturally aspirated engines.

This topic has been up so many times at work (additives) that if I had a nickel everytime I'd heard it, i'd be... well, rich would be too much to say :p.
