Terry,

Power Plus Fuel Enigne Systeem (or whatever).

I normally don't believe in fairytales : but if you say it works and has been objectively tested then we have to believe you, I guess.
Does it work on the older (LR)dieselengines as well? Any comment.
Quanta costa?

Karel

Yep,

More powerful engines in your Disco: if you have the cash and time: fit in the gearbox from a 4.6HSE Range Rover. Driven with a little bit of respect, this will keep up with even the 6.5 V8 turbodiesel.

BTW, why not buying a Hummer!!! Shouldn't always be Landies (still the best) or Toyos.

I don't think lockers (ARB or whatever) are a good idea in sand!!

Use thicker engine-oil : 20W50 or even thicker in hot conditions. No experience with Millers XFD.

Terry, you may have heard these questions before, but I can't resist expressing my doubt about another instant cure to all the mankind's problems:

Why? What chemical/physical processes must occur before it starts working as advertised?

I am not sure it it does pay for itself so soon, if at all (it costs UKP 165). Even if fuel consumption would drop by 5%, I would have to pump ca 4500 litres of fuel through this gismo to break even. If I restrict fuel supply to the injection pump I also get less smoke, burn less fuel, don't have to wait a couple of thousand miles before it fully beds in, and ... pay nothing at all.

I’m not a chemist. Presumably over the first couple of thousand miles the entire fuel system gets impregnated with the magic minerals. Perhaps the cylinder head is affected - I don’t know.

The measurements on the TD5 showed two things:-

(1) You cannot measure fuel performance yourself. I had to drive the same 52 mile circuit five times to get an average reading. I was trying really hard to drive at the same speeds and in the same gears around the circuit, and was being timed with a stop watch over each section. Despite this there was up to a 10% difference in fuel consumption on different runs.

(2) After the PowerPlus unit had been switched on, the average for the five runs after, compared to the average for the five runs before, showed a significant drop in fuel usage.

Laurie Wright, the LRO observer, commented that I was driving more aggressively on day two (PowerPlus switched on). I was a bit miffed at this remark because I didn’t think I was. I realized afterwards that what Laurie had detected was the improvement in the power being delivered. I wasn’t giving it more welly, the engine was delivering more welly.

Anyway, you’ll have to believe me about the power increase. But I suggest you ask PowerPlus to send you a copy of the report and read the facts about the fuel usage.
