Former car restorer, damper designer, rotary-engine guru and also an automotive engineer, but generally doesn’t talk much about his former activities. András is our mag’s Leatherman tool: when there’s a project no-one would poke with a stick, he’s the one usually assigned to carry it through. When he’s in Hungary, he works 16 hours daily, then every once in a while he disappears from the horizon. Last time he’s been seen in Auckland… Has a huge garage, lives with a girlfriend.

You could recreate the hyped Fuel Shark Saver for a fraction of the price of the original. But is it worth it?

I lost my senses. The fuel consumption reducing craze took me by storm. I got hooked. I saw the FuelShark Saver and knew I had to have one. But an illicit one.

There's no gadget an ingenious Hungarian can't reproduce for a fraction of the price of the original using parts found in garden sheds and bought under the table. Hell, a cigar-lighter plugin faux fuel consumption reducer can't be the exception.

I took the thing apart. It wasn't hard; the only difficulty I encountered was finding the spring pushing the knobble of the cigar-lighter connector after it had sprung off. You can get the tip off with a single pull, flip the blue transparent plastic off easily, and from there you are only a Phillips screw away from the Big Secret.

I have good news for everyone on good terms with the soldering iron. Even if you buy your parts in the most expensive shop, the expenses of the fake Shark Saver will be little over €3. I may be putting my life at risk egging you on to fabricate a fake of an obviously patented gadget, but taking full responsibility I hereby present you a list of what you'll need:

1 2200 μF, 16V electrolytic capacitor

2 1 kΩ, 5% resistors

1 1.5 MΩ, 5% resistor

1 LED

1 glass fuse

Now, please work out the wiring diagram by looking at the picture.

I'm thinking what if I used a 4700 μF capacitor instead of the 2200 μF? Would I enhance the effect, or can fuel consumption not be reduced beyond a certain point and the makers of Shark have found that optimal value? And what if I soldered the whole thing directly onto the generator? Wait, no, there's already a filter capacitor there.

I admit I look up to the inventors of the Fuel Shark Saver. They have built their business on the most fixed point of the universe: human stupidity. I know it's a scam and all, but I'm one of those people who believe they deserve it. If I was Chinese, I'd produce its clone called, say, Fuel Snark Saver.

To be honest, I took the gadget apart because the readers of my original article run by the Hungarian edition of Totalcar demanded a dissection. Of course we've always known what was inside; now we have photographic proof thereof.

An Italian car without issues?

The recipe for the cheapest car in Europe seems to be the Dacia Logan nowadays. But just wait, there's another choice down the line.
