You are experiencing the same thing I am. No change, with ARX in the oil and tranny.

Just filled up with 8.595 gallons of gas....$3.36 a gallon
Mileage on gas was 195.5, and MPG is 22.74.
This is the first tank without Auto-RX in the transmission, and no different driving habits than normal. I would say the only difference is that the A/C is running more often. The car is in good tune, new spark plugs, PCV, air filter, cabin air filter
,and oil before the Auto-RX went into the tranny. I would say that so far, Auto-RX is making little to no difference for gas mileage. But, I am sure that my tranny is cleaner.

For 20-25 bucks a bottle, I would have run it longer-just my opinion, of course- you should follow the instructions on the website...
It takes at least 150 to 200 miles of driving with new transmission fluid (after using Auto-Rx for 1000 miles and cleaning out unit most importantly the torque converter) it seems that "Coop" has done application correctly. His next post should be at 200 miles and than we are done with this test. The purpose is it is an adjunct function to work with the engine in helping to save gas.(Transmission itself is not the key) a major benefit is clean clutch packs-smoother shifting and keeping the transmission operating at peak efficency
I also get the sense that some believe once Auto-Rx hits the oil results should be immeadiate. NOT SO !!!

bmwtechguy Auto-Rx Price of $ 24.97 includes shipping ($7.95 for 1 bottle anywhere in the USA) so lets be fair subtract shipping from the total price and Auto-Rx costs $17.02 per bottle. i will be glad to sell you product and you pay for your own shipping anytime any quanity.
Auto transmission maintenance is likely the most neglected part of car maintenance. Probably the reason whyt transmissions are considered the weak link in many brands.
But after ARX cleaning a neglected tranny and new fluid purged in, you can start saving MPG. You first have to start driving like an old lady for a week or so, depending on driving requirements. Don't get me wrong I have nothing against old ladies. By keeping a very conservative left foot on the gas pedal the shift points will likely change to a lower engine rpm before upshifting. This can save fuel.

Well, I see they moved all the posts........
That's funny, all the old ladies I know drive their cars under heavy load and way above the speed limits. Yet I do conservative driving and do not exceed 3-5 mph over the limit, but I get labeled as an "old person" driver.
Okay, filled up the tank with 13.473 gallons. Mileage on the tank was 305.0. So, MPG was 22.64. I am seeing no change what-so-ever with the transmission cleaned with ARX. So, I am done with this test. My assumtion is that my tranny is cleaner, but MPG is not effected by cleaning my tranny with Auto-RX. I hope it works for someone else. I am done with this test.
Honestly. Statistically you really can't reach any meaningful conclusions. In statistical analysis you need to have a minimum of 20 samples and really you need several times that amount to be able to get sufficiently meaningful low margins of error. And all this assumes you have gotton rid of interfering variables...similar temperature days, similar trips, same gas, etc.
I also though do admire your efforts...cudos to you.

Okay, I see 50/50 in this thread. The OP and I have no results, and this guy and Shelby do.
What criteria did you use to say you had no results?
The same statistics used in this test. No mileage gains.
I've had some very positive results using ARX. Oil leaks have been reduced / eliminated, the engine becomes much more responsive, etc.
Better gas mileage is always welcome but there are so many vaiables to achiving it. With a cleaner engine / transmission if the conditions are right you can get better gas mileage. I know in a couple of vehicles the best single tank mileage numbers were produced during / after ARX usage.
I really would not expect normally to see much in the way of mileage gains after a ARX treatment. If you went from conventional to synthetic or from a thick oil to a thin oil you might see some gains. However unless you kept very detailed records you might not be able to detect any improvement at all. Some vehicles are more sensitive to lubrication variables than others.

Why would you think cleaning a transmission would improve mileage? The ratios havn't changed nor the diff ration so how could you possibly think mieage would go up? Your mechanical knowledge is not your strong point is it?
I am unable to verify ARX use in my manual tranny for MPG purposes. After adding the ARX, I got only two tanks of gas logged before I noticed one tire was past the wear bars. I was expecting to go a few more months before getting new tires, but had inside shoulder wear on one side, despite the alignment being w/in spec. New tires gave an immediate 0.75-1.5 MPG decrease seen over many tankfulls.
Non-hard data: shifting seemed improved during the cleaning phase of my MTX - *slightly* smoother synchro engagement sometimes. After replacing the fluid (same used before/after: Redline MT90) - shifting is the same as its ever been - no better / no worse.
Since fluid is what powers the vehicle, I think good fluid and unrestricted flow is rather vital for a transmission, and since I have a non-lockup convertor, and I am always using the fluid to move my car, again, I think that clean=better, but please, accuse me of being wrong. Besides, it's the owner of the product you worship that started the idea, maybe you should ask him.
Originally the purpose of this test was to clean both the motor and trans to see if mileage gains were a likelyhood.
Simply cleaning a typical lock up auto or a manual could not increase mileage. However I still beleave that those that have cleaned there trannys up would likely benefit from mechanical longevity.
Shaman, I recall that you picked up this Mazda Az wagon used, in a state of mechanical disrepair. It had some serious motor oil consumption issues, even with relatively low mileage for a 1995. It is possible that what you have is some mechanical wear, which ARX can't repair. In other words the problems are greater than just dirty stuck rings.
