Anyone using magnets to increase milage?

[MetroMPG]

The instant read-out isn't the best approach.

The better approach is resetting the average consumption at a set point, then reading the value at another set point.

You want to use lab conditions right in your driveway? Apply a constant load to the engine at idle and watch for fuel consumption for a couple hours to establish an average, repeat the test with the same outside conditions with the magnets, and then repeat it again without, then again with, etc.

Do this about 16 times for each set of test parameters (with magnets, without) and get the fuel for the tests ahead of time so that you're using the same fuel batch throughout the tests. You will note a loss of fuel economy which can be identified on a curve throughout the test procedure as the fuel ages, but I doubt you'll be recording hourly fuel economy numbers in multi-decimal (4+) formats, so it may not even show up.

Try on a fully warmed up engine using a 1 gallon test tank/cell for 1 hour with no magnets, then again with magnets, then again with no magnets, etc. Keep refilling the tank and noting the fuel measurement required to fill the tank to a predetermined level.

Record data including underhood and outside air temps, specific air density, humidity, etc. They will all be required over the course of testing to discern differences in numbers compared to environmental differences. Too much variation over the test course will invalidate the results.

I have a digital camera, so i can take pictures of anything you want. I can take video of mpg gauge in action at anytime, I can get instant read of mpg at that moment, (I will have to start reading over).In my experience, once the vehicle is warmed up and acheives top cruising speed I can do instant read and the mpg will stay steady if on flat straight road.The only time the milage would start at a level and continue to increase was when I first put on the Magnets and they were making thier effect.

As has been tapped you will need an average rather than an instant - instant MPG will vary from under 20 to infinity depending on instant circumstances. An average, reproduceable over a repeatable route is what we are after with my method.

Its a little like measuring the energy your house uses. If you take an instant value then it could be that the oven is off or the heating is low or the opposite of those of those making the reading low or high. If you take it over a month that is better but summer months may use less (depending on your need for AC - I live in Scotland so that isn't required ) so it may not be representative. Take it over one year is much better as you go through the variations of seasons and weather. Over a number of years is better still as it also takes into account any weather extremes - e.g. the heavy snow we had in 2010 but not had since.

Anyway, I shall await progress and results

This is the sticky wicket on this forum.....ABA testing and issues of allowing the ECU time to adjust. LaPointe mentions this....where he recommends to NOT reset the ECU. My cone filter results verified some kind of ECU adjustment as monitored by a SG over 2 tanks.

Some mods such as tire pressure will show instant results....others involving fuel management and the ECU take time to evolve.

The time to test this is in summer after temps stabilize?


In the interest of full disclosure...etc...I need to CORRECT the above info:

* I did see real mpg gains over 2 tank refills vs previous tank refills...before temps started to trend down.

* The ScanGauge Fuel used reading also needed to be reset lower over these 2 tanks...confirming the tank refill mpg gain.

* The ECU was probably not involved directly...that I know of...in this mpg gain.

I think in this case the strict a-b-a test should be waived because the only way a change in milage is achieved is through a change in ECU. With what I've read about ECUs is that they don't change quickly, they can take anywhere from 5-10 trips before behavior is changed, if ever without disconnecting the battery and erasing it.

Trip has started, Downloading pictures to photobucket.May need help getting a link.
Two days of highway driving. First day snow and cold temperatures low speed driving Best mpg was 29.6, 400 miles. Second day 35Degrees rising to 55 degrees 70 -77 mph
377 miles, mpg didn't vary .3 mpg. steady 26.3mpg. Looks like at those conditions hat is max number.
Since I'm burning available highway miles, going to attache air magnets only for next leg of trip 300 miles. Then it will be city drivng for 3 weeks. then another short leg. I will attache gas magnets on return trip to give highway time.
I am using photos to show all dash gauges, rpm, mpg, milage intervals-100 miles,gas stops. I will try and match same conditions todays drive to see if air magnets change any ecu settings (rpm).
For mpguino reset concerns, my mpg shows both instant and average reading simutaniously, so there isn't change delay.
Photos are in pairs, showing milage on one and mpg on other. Pair by looking at milage reading of matching photos.http://s1089.beta.photobucket.com/us...do434/library/

Another variable is elevation change. I regularly make a trip of about 60 miles, with 800 foot elevation change (13 feet per mile). I average 27 to 33 MPG uphill, and 30 to 42 MPG downhill.

Two more variables:

Wind direction and velocity.
Temperature.

Those two variables are why my mileage on the downhill trip has varied from 30 MPG to 42 MPG. Crosswinds are slightly worse than headwinds on my truck.

Jrmichler, Thanks for post, I am traveling at sea level, so altitude shouldn't be a problem. Wind has been benign, (not noticable, but will keep eye on it).
tire pressure has flucuated between 34 and 36, as heat built up in tires. No rain or snow in last leg. traffic moved evenly.
When I put air mags. on car last time it was after the gas magnets, so it will be interesting to see the effect by itself. The air magnets increased the milage about one mpg and helped vehicle obtain max mpg faster, timewise. Meaning, It took all day driving for just magnets to get to maximum mpg, with air magnets added it acheived max mpg in only hours.
I will take picture of installation of air magnet and intial guage readings.

I put some neodymium on my front bumper and get real close, oops too close !! just dont put any near your cars computer, could be trouble

[bestclimb]

so many variables, so few controls

[hondo434]

Change of plans, Somehow the air mag setup I brought along has gone missing. i put together with the gas mags. Maybe they got stuck to something. if they show up I will use them.
I installed the gas mags instead for the last leg for awhile. Will post results on photobucket.
