I respect the combined knowledge of the FR world.

[Atlas Sneezed]

Absolute, total bunk.

And I didn’t even check which bit of quackery this one is.

[tcrlaf]

It’s REAL SIMPLE:
Get a tuneup...
Properly Inflate and Balance your tires...
DRIVE SLOWER....

Save the money you’d otherwise be spending for Gas. We saw all kinds of scams in the late 70’s that never lived up the lofty savings promises.

I have read quite a few articles in various mechanics and car magazines and none of them really work. I think a few things work to a small degree but typically are not worth the extra trouble and expense. An example would be methanol/water injectors. I think they work but you probably would end up spending more for it than it would save.

[Randy Larsen]

We need more info on which SUV’S you are driving.

[PapaBear3625]

The only thing you need to ask is this: given the intense pressure that car companies are under to increase fleet mileage, why didn’t they put it in, if it works so well?

[expatpat]

I'm normally a cynic on stuff like this. However, this time, I think there is something to it. I believe it has been shown that a small amount of water injected with the gas/air mixture can improve the efficiency of an IC engine.

However, I suspect that the 25% claim is vastly exaggerated.

Hey, this one can double your mileage!

Real quick test: Why would GM, Ford, Honda, Toyota etc etc etc all sit around and ignore something like this?

You know the old story about the intermittent wipers....backyard inventor....big car company STOLE his master stroke invention....wouldn't pay him. Had to sue.

IF someone from Aquatune starts SUING GM because GM incorporated it into their SUVs, THEN you can assume it works.

It was relatively easy to install the AquaTune, although we did need a few feet of our own vacuum line. (What do you want for $399?) Unlike the pump-fed water-injection systems on P-38 fighters, the AquaTune relies on intake manifold vacuum to pull distilled water from a plastic bottle and into the manifold. So, at periods of wide-open throttle, virtually no water should enter the engine.

THE DYNO SAYS: With the AquaTune adjusted according to the instructions, the test truck gave us 20 fewer horsepower and about a 20 percent poorer fuel economy.

[Fox_Mulder77]

Big time scam............ and I mean......... BIG TIME SCAM!!!!

[btcusn]

Save your money. It’s bull.

The business model is:

Get a bunch of suckers to send us $500-800 for this crap. Assume that a significant percentage will never get around to installing, or will not really measure the effect, or will measure inaccurately and end up with a favorable result, or will feel so stupid they tell themselves they got a good result, or who get a bad result but don’t get around to returning the product.

Take all the returns you get, and sell them for $75 off as “remanufactured.”

Refer to a “disclaimer” in the materials, but never reveal what that is until delivery (no refund on shipping? hoops to jump through that make returns even more difficult?)

[MindBender26]

They are claiming to break water down into it's components, hydrogen and oxygen, then burn the “free hydrogen.” They may also be dumping the oxygen into the air inlet, which would also increase power.

I don't know of any “reactor” that would do that. If they are using electrolysis, then the electricity consumed would probably take more energy to make than any savings from the Aquatune.

[True Republican Patriot]

Dont waste your money.

[Sunnyflorida]

Go for it.

The fact that a good percentage of FReepers cannot pass a high school science or economics test is no reason not to waste your money. Buy a few packs of Lucky Strikes while you are at it.

[gogeo]

No, no, no.

Drain your differentials, transfer case, and transmission. Convert to synthetic. You'll get that 25% mileage increase.

[gogeo]

No, no, no.

[Mr Ramsbotham]

If it did, you wouldn’t have any doubts.

[Dan(9698)]

Would love to cut my milage twentyfive percent

Drive like you always do, and pour four or five gallons of every fill up out on the ground.

That should cut your mileage as you desire.

[the invisib1e hand]

it used to be, that if you drilled little holes in the barrels of the carburetor -- the holes had to be in direct proportion to the height of the Great Pyramids and with exactly the same aspect w/r/t True North as the Pyramids (the holes, that is), and at an upward angle of exactly that matching the angle of the Pyramids from base to peak, that you could drive from one equinox to the next without refuelling on a single cubic span of high octane gasoline (the octane being in some proportion to the Golden Mean).

But all that changed with fuel injection. This information was recently declassified.
