 2012 TDV8 Vogue (L322)

Load of old tosh. If it were that great manufacturers would do it already.

In the same bucket as magnets on the fuel line for me. 2012 (L322) 4.4TDV8 Vogue SE, RSE, Fuji White over Arabica.
Previous V8s: BMW 645Ci, P38 4.6, P38 4.0, Merc CL500
Previous others: Honda x1, Volvo x7, Rover x6, BMW x6, Ford x1, Mercedes x2, Skoda x3, VW x2, Renault x2, Citroen x1, Mazda x3, Nissan x1, Audi x3, Kia x1, Fiat x4, Subaru x3, Austin x2, Triumph x2, Jeep x2, Hyundai x2, Lexus x1, Mitsubishi x1, Saab x2... and some others I've forgotten!

Hehe, that's made my evening.

OP - please don't fall for it. Pure snake oil. 2006 L322 Vogue SE 4.2

About as useful as those 13a plug adaptors that "save a fortune".

y'all mighty reactive, that's good. "it needs some intelligence to undestand you may not have enough"

Friend of mine played about with this sort of thing several years ago ( chap near him made the same sort of units and wanted someone to fit them to customers cars),out of interest he fitted one to couple of his own vehicles a v8 diesel chevy blazer and a v8 petrol ford pick up and the v8 petrol mpg increased to be on par with the blazer on straight diesel at 22/24 mpg on a long run from about 16/18 mpg, the diesel also showed an improvment of couple mpg if I remember right, also fitted a couple to a 44 ton truck ( mpg also showed an increase) the problem there was it didnt have one driver so the unit didnt get topped up so burnt out. In the end there wasnt enough interest in them so the chap making them gave up, my friend still has the two vehicles ( blazer parked up for years now falling apart and the ford is a bloody terrible ride glad he only puts it on the road in the summer ! ).

Yes, a load of nonsense.

The theory seems logical - use waste power from the engine to run an electrolysis unit to produce hydrogen, however the amount produced is so small, it's unlikely to make more than 1-2% difference in fuel economy, if at all.

The solution to a more economical Range Rover, is not to have a Range Rover. 2015 Range Rover Autobiography 4.4 SDV8

Is it April 1st already?

Must fill the kettle with some oxygen hydride for a quick cuppa  Got - 2017 SDV8 Autobiography in Loire Blue
Had- 2008 TDV8 Vogue SE in Java black
Had - 2007 S/C in Stornoway Grey

The only way it could generate electrolysis without using fuel would be if it only took power from the alternator on the overrun.

By my beer mat calculations the 0.01mg of hydrogen this would generate would result in a fuel saving that would take 400³ years to return your investment at current fuel rates.  2006 L322 Vogue SE 4.2

Very true.

So functionality should only be limited to long downhill runs, preferably with a tail wind. 2006 L322 Vogue SE 4.2

Whatever else was going on, an HHO generator would not make any changes like that. The electrolyser requires electrical energy, which has to come from the alternator, which is driven by the crankshaft. Any energy added by the electrolyser has to come from the energy going in to the system. They're snake oil, pure and simple, unless someone has figured out a way to cheat the basic laws of thermodynamics.

It's genuinely far more likely to be placebo effect or the owner trying to convince himself that he'd not wasted his time and money trying to cheat the basic universal laws of physics. 2012 (L322) 4.4TDV8 Vogue SE, RSE, Fuji White over Arabica.
