Anyone using magnets to increase milage?

[Arragonis]

hondo - please read the ABA post linked to twice above.

In your original posting you claimed an instant improvment but that was ont he same route in different directions. What you want to do is to create a test with the minimum of variability except for the mod you are trying to test.

But as you asked how about something like this :

1. Select a route, maybe a circular route round a city or town on a highway, some route you can use cruise on consistently. Make a note of things like temp, wind direction, weather etc. Photos are good too.

EDIT - route should be a decent length - 50-10 miles at least, car should be warmed up etc.

EDIT2 - All runs should be in the same direction.

2. On your route select a start and end point - e.g. a bridge.

3. Top off your tank and do a number of runs on cruise unmodified - reset your MPG gauge at the start point and note the average at the end point. See how consistent they are - if they aren't then maybe change the route as they should be very similar. How many runs you do is up to you - one probably isn't enough, 10 is maybe too many.

4. Fit the mod.

5. Repeat 3 (including topping off you tank) with the mod fitted. Again the results should be consistent with each other with the mod in place.

6, Remove the mod.

7. Repeat 3 - full tank again. Again the results should be consistent with each other without the mod and should be similar to the results in 3.

For best results all of this should be done in one go - so you have the same weather, temp, wind etc. but that can be tricky and even inside a day the weather can change but we don't all have testing labs. Topping off your tank each time ensures the weight of the car is similar.

For bonus points take photos or video the test - a mobile phone is good for this but for safety use a mount when the car is moving - decent ones are $15 or less on Amazon. The more evidence you have the better the test.

Look forward to the results.

Arragonis, thanks for reply and recommendations, I am pondering how I am going to adapt my trip to the testing. I may do a tankful method maybe two tanks, to try and get a base mpg, mainly because of the mountains I have to cross. Maybe I will be able to do the measured mile part while I'm in Florida where it is flat.

[Arragonis]

Sorry mate but I have to disagree - you need a repeatable baseline and then measure an improvement. I wouldn't use a single trip (even if you have done it before) as a reliable measure - too many variables.

Enjoy the trip and do the testing afterwards maybe.

Good luck on the trip anyway.

I would add to this a couple extra runs. The person doing the run should not know if the device is installed/active during the run

Repeating the run without the change (the second A in an ABA test) is especially important. If the mileage differs from the first A run, the test itself was not accurate. Which is why an ABABAB test is even better than an ABA test.

Here is my two cents.
1. must be using a scangauge or some system BESIDES filling up to determine mpg.
2. Assuming 1, then set cruise at a fixed mph and record results from scangauge.
a.) temp, rpm, ign etc
3. Where it is flat for a couple hundred miles, record then stop, clear gauge, put magnets on, and record.
4. record in the same place on the return trip..
5. BEFORE the trip, set up a basis for your car, running on a flat area to establish a baseline.

Now, if you decide not to do this, don't try to present to us that the magnets 'worked'.

[mcrews]

I disagree with some of the comments (just a little)
I had a 12 mile stretch in Sacramento where I did ALL my testing. I would run up and down and log both. Partly to show, that in fact, different directions do produce different results. Also, it gets you back to your next run! (so why waste a test run!!!)

After 5 yrs and 200k miles in the BEAST (Q45) I can assure you that method was absolutely predictable.
I alsway tested on warm dry days (over 75 under 100)
I would reset the Scangauge on reach run.
I always used the cruise for the run.
always used a landmark at each end (bridges)

But here is the bottom line.
CONSISTENCY (not distance)
A warmed up engine on a warm day will perform the same at 10 miles as it does at 1000.

• TEST INSTRUMENT CRITERIA: The test equipment MUST be 10-times MORE accurate than the data values being measured, ie: 10:1 precision/accuracy ratio!

Thus, if you want X.X results, you must accurately measure X.XX values.

scan gauge and similar do not really show fuel metering. they know the air flow. the only thing that sees exactly what the injectors are doing is an MPGuino. If the magnets are actually doing something to the fuel, and the computer is sending less, this is the only system other than actually measuring the fuel flow via a highly calibrated tank that will show fuel flow accurately.

I mentioned before that I think it is important in this case for the test to be blind to the operator.
