Has anyone tried any of these magnetic fuel saving devices like Ecoflow on their cars? Most of the stuff on the net about such devices from a variety of makers says they work, and all give a similar scientific explanation of how.
Do these things give fuel savings of up to 10%? I worked out that if I bought an Ecoflow for £50 and it saved me 10% (55 mpg instead of 50) in fuel, it'd pay for itself after 7000 miles.

S.S if you believe all you hear.you could spend a fortune.They have been going for years.I think back to 70`s threads have been made on this here.would suggest a full service better than trying this.it`s up to you but would forget it.They are not known to work.So Beware.

Spud - 2 questions ;-)
1 - if they worked, wouldn't at least one manufacturer install them, so they could say 'look, our cars ar 10% more economical than everybody else's
2 - have you tried doing a forum search on ecotek / ecotec / snake oil ?

I am sceptical about these devices too. But they've been about for ages and the principle, whether real or imagined, is well known.
I think I saw a test on TV where real savings were measured. I imagine that the savings don't amount to much, though, so it's hardly worth fitting the devices.

Dont waste your money.as I recall no test has proved they work,

Using the Forum Search, browse for "Pilot Green". Several posts relating to these magnetic devices.
Here's one for example:-

Ask yourself this question: fuel is made up of hydrocarbons that are electrically neutral, so how will flowing through a magnetic field affect them? If it was that easy, the NMR spectrometers where I work wouldn't need electromagnets weighing half a ton!

Its like the saying- 'if it sounds too good to be true it probably is'.
Anyway, changing driving style, checking tyre pressures, regular servicing etc can all result in gains at the pumps!

You may find these articles an interesting read to dissuade you from wasting your fifty quid!

You may also be interested to know that the ASA (UK Advertising Standards Authority) apparently ruled against Ecotek during April this year.

Keeping your right foot pressure as low as possible is the best fuel saver; alternatively use Shank's pony or a bicycle.
Along with the suggestions about regular servicing, tyre pressures etc.
A fool and his money are soon parted, which is how such devices come to be on the market.

Frequently to be found on eBay in bulk for c. 100 for £10.
Then your only problem is to find 99 other gullible people.

Maybe fitting cars with smooth plastic undertrays would be the easiest way of saving a few mpg. A lot of attention is paid to aerodynamics of the bodywork we see, yet most cars are a mess underneath. Obviously there would have to be a gap around the engine, the exhaust pipe and the wheels/suspension. A plastic undertray would have to be made up of more than one section and be removable. It would also help prevent mud build-up on the car's steel structure.

Most modern cars have engine trays now so no need for a gap, unless you meant a gap for the hot air to come out through, well the hot air would find a way out, just leaving a few inches here or there would do it. Or put a vent through into the wheel arch.
I like your idea of a bit of body shell under the car.
Re: Ecotec it works by fixing it to the inlet manifold, usually in the main vacuum hose (from brake servo?). The unit is designed to allow a pin hole of air to flow into the manifold. As the air comes in the unit makes a noise (caused by the air coming through some sort of valve). It makes a noise so you can feel good about buying it, "at least it's working" you think to yourself as you drive along.
I played with the ide of buying one for my taxi, because as a taxi driver I knew exactly how much fuel I used each week, as I had pretty good fuel records, so any benefits would have become fairly quickly noticeable to me. I decided against it because:
1. I used LPG most of the time and that was dirt cheap anyway, and I thought the unit would have less chance of working with LPG than it did with petrol.
2. They didn't offer any money back gaurantee, all they offered was a choice of four colours, for something under the bonnet that made a buzzing sound.
If it worked they would have it independently tested under laboratory conditions, constant load. But they don't so all they have is dubious customer testimonials "It worked for me!" The only logical conclusion one can reach is that it doesn't work and spend that 50 quid on a new power tool instead.

I once came across the Posivlow version of these, in one of those "everything a £1" shops, so i bought one for the heck of it. I put it on my 2.5 V6 Mondeo, left it on for six months and was amazed. It didn't work ! 8-( What a waste of a £1. So I took it off and sold it on Ebay for £2. Let's face it, if (as it claims) it magnetises the fuel molecules and aligns them all for neater burning, them what happens when they pass through the injectors which are solenoids (magnetised). Do the injectors then demagnetise the fuel ?

Another favourite on eBay are the mobile phone power boosters, and radiation shields - even cheaper.
You could make up a 'totally useless gift pack' of these three items.
