Anyone using magnets to increase milage?

[hondo434]

Back from Florida. Had removed magnets on way down. Put magnets on fuel line only for return trip. Terrible traffic and accidents up to Richmond, so I reset computer from Richmond to home. Smooth sailing, 30.1 mpg with average speed at 59.4.

This really doesn't prove or disprove anything.

Let me compare - my journey to work is uphill and I get typically 5-10 MPG less then when I go home again, downhill.

Lets say I think having a Unicorn horn on my car will make an instant MPG difference because of "magic". OK it's a theory.

If I strapped a unicorn horn (sustainably sourced natch) to my car's bonnet for the journey one way and then removed it for the journey back it means nothing.

If I spent a tank with it off, then a tank with it on, and then off again then maybe I'm starting to get something meaningful. More meaningful still would be a closed track or reproducable section of road where I could test the effect repeatedly - maybe 5 times without, 5 with, 5 without.

You've had the A-B-A testing description tapped here loads of times. Do that. Anything else is just wasted electrons.

You could put your travel / MPG log into your own thread though, that would be fine

Arragonis, Here is results from last trip. About 27ish both ways with and without magnets. This last trip with magnets was about 30ish. While this is not earth shattering numbers but it is an improvement over last time. I'm not going to be able to do the tests scientists require, I'm just trying to make a difference in my own way. Thanks for your remarks.

What other changes are being made, with vs. without?

What I would really like to see would be tests back-to-back without human intervention, some round trips on flat, level road at moderate speed, long enough to get some solid data, and with the speed maintained by the cruise control.

The cruise control takes out the human factor. Just with a little careful manipulation I can radically alter my car's fuel consumption to the good or bad, and it doesn't matter if there are magnets under the hood, in my pants or even in a big box in the trunk with a hundred pounds of other magnets. The cruise control will attempt to rigidly adhere to a specified speed and can be counted on to make essentially the same adjustments over each run to maintain that speed. Test THAT way and post your findings.

Your results with your Altima aren't especially noteworthy compared to others in the Ecomodder garage. In fact one Altima - a year older than yours I might add - consistently posted better numbers. Even his worst record was better than your best, and while he admitted that he ran a partial grille block most of the time, he also laid the credit for most of his results at the door of driving style. So while it is possible (I say that in the interest of scientific accuracy, but I give it little credence) that the magnets are having some positive effect, I say it is far more likely that you, having the expectation of a result, are actually effecting the result by your own, probably unconscious, actions.

elhigh, If you can be more specific on your comparison with the other altima , maybe I can give response. My altima is a 6 cylinder, not 4 like 95 % of altimas. Driving Style is personal and I can't comment on that. I use cruise whenever possible.

There's nothing stopping you from looking up other Altimas in the Ecomodder garage pages, but since you asked:

2005 Nissan Altima SE Gas Mileage (Slowest. Altima. Ever.) - EcoModder.com

His best results are getting into hybrid territory. I checked; his is also a V6. His techniques and the two modest modifications have been thoroughly tested by many others in these pages.

Here's my proposal of how to test whether magnets help FE: Narrow down the parameters as much as possible.
Does putting magnets on your fuel line effect aero? No.
Does it effect rolling resistance? No.
Does it effect electrical load? No.
Does it effect transmission losses? No.
Then factor these out from any comparison tests!

Magnets are supposed to improve combustion efficiency by "magnetizing" the fuel molecules, so test a bare engine* on a dyno - at all of the rpms and loads seen during driving. Test at different ambient air temps and pressures. Check the fuel used by weighing it. Eliminate as many factors not related to the magnets' properties as possible, and what is left will tell you the truth.

*) To make this a blind test, the engine should not know whether the fuel has a magnet on it or not.

My proposal for testing magnets has nothing to do with Hondo, because we will never, ever get anything useful from him.
