Classic fuel enhancer!

[crankedup]

Purports to improve fuel efficiency and boost fuel economy. Tried and trustedused during WW2 particularly on high performance aircraft including the Spitfire. Gives extra power and performance.
Claims made in the publicity blurb are truly remarkable,
enable virtually all petrol engines to run on unleaded fuel, even high performance engines.
Improve on and return lost power.
Reduce dramatically the formation of carbon deposit.
Instant improvement of power, acceleration and top speed.
Save money by using lead free petrol.
More MPG
and it goes on.

It features the new triple magnetic field which excites and induces correct molecular structure alignment of the fuel and the adhesion of the metallic molecules essential for maximum power and performance lacking in lead cree petrol. And so it goes on.
Yours for a princely £39.95.

My guess is that this devise was introduced sometime mid 1970’s maybe slightly later. It’s still fitted to the car and I have no plans to remove it. A good talking point when interested people look and ask ‘what the hell is that’?

These things have been around for some time - a metal cylinder that goes in the fuel line? Every now and then someone will think up a new way of marketing them, they'll have a bit of a resurgence, then fade away again. I seem to recall that there's often a stand at some of the classic shows I go to where these are being sold.

That’s it, a metal tube thingii bob, at least the fuel isn’t leaking from it.
I seem to recall some years back the marketing of a form of tablets that go directly into the petrol tank. Again promises everything except a trip to the moon and back. Do people really still buy these type of things

You only have to remember the BMW April Fool adverts of the 1980 to say yes to that. Just have a look here to see some of them:-

And I can vouch for the "Badgewash" one, because I was at the dealership with my 325i when an irate customer came in demanding to know why he hadn't been offered the option when he ordered. I collected some of them from the Telegraph each year, framed them and put them up in the reception at my offices.

When I collected my Riley after buying it, the seller mentioned he'd put some of the pellets in the tank - whilst handing me a half-empty bottle of fuel additive...

There's a seller on Ebay still flogging them and judging by his feedback people are still being taken in by the 'technology'. For £12,999 you can even buy into it and make your own millions.

There was one flogging the metal pellet in the tank type at a small show I went to at Market Harborough last year.

Probably best not to look at the goods & smile. He then got quite annoyed when I showed no interest in either his wares or his patter.

I'm convinced, where do I enlist for the next test...?

I bought a very low mileage Maestro VDP that had the bag of lead additive in the tank , even had all the sales blurb and instructions and sales receipt for it .
The irony was the engine was of the type for unleaded anyway .
