FUEL Economy-Out Of Warranty? Who Cares?

Water injection (or water/alcohol mix injection) has been around for a long time. But it isn't usually setup the way the Aquatune does it (using the intake manifold vacuum to suck the water in). And some of the claims (using ultrasonic energy to create hydrogen from water) are just ridiculous.

Popular Mechanics did a detailed study on this a while ago:

Yeah, I have figured out a way to get WAYYYY better economy. I leave the car parked in the driveway and ask my friend to pick me up.

Thanks for the honesty!

Most people hawking their wares hide behind anonymity. Not you, Administrator!

The thing that has made the biggest difference to the fuel economy of my '94 940SE turbo diesel estate was taking the roof rack off.

A full tank of diesel (with roof rack): 400 miles. A full tank of diesel (no roof rack): 450 miles.

No significant differences in type of journey or driving conditions between the two tanks.

I get around 500 miles per tankful with mine. Am just checking the mileage again as I am running on processed used chip oil (100% Biodiesel). I expect to get increased mpg, it is certainly smoother and has more power and, of course, better for the fuel pump.

All the best, Peter.

I've had a lot of experience with water injection over the years and have never been too impressed with the effects except for reduced detonation. Popular Machanics did a test on the aquatune system but they had it completely incorrectly installed. I do know one thing and that is that my overall mileage on my XC has gone from from just under

22 mpg overall to just over 29 overall, without steam constantly coming out of the tailpipe on a really cold morning as I have experienced in other setups. This is without any difference in driving conditions, except that it's a hell of a lot colder these days. Both Mercedes Benz and BMW have experimented successfully with water injection and hydrogen separators dating back to the '60's and the only reason that the units were never included on anything from the factory is that they decided that their demographic didn't care one way or the other. You may takethe elitist attitude and poo-poo the system if you care to but I only know what I see at the pump and figuring it out on a calculator and with the onboard computer. The figures just don't lie. You may also call it "rediculous", but on the news segment and also on my unit, you can hold a lighter up to the pipe that goes into my throttle body and you'll actually get a little "snapping" hydrogen explosion from the end of the pipe. You can also put an engine stethoscope up to the "heart" of the unit and hear a very high frequency tone coming from the inside. I don't believe very much these days when it comes to things like "turbulators" that are placed in the air stream, but I can't dispute the figures.

Yeah...? Good for you! I sell real estate and unfortunately I don't have that luxury. I CAN tell you one thing, however, and after this car is no longer serviceable, which I think will occur within the next year or so, the BMW Three series is looking better and better...Or even a Lexus.

Congratulations to you, you little puke...you know how to change quoted text...i'm impressed. Try actually reading my original post.
