On top of that the owner/inventor is very cut and dry about his product, how it works and what it can and can not do. Some people find it difficult to deal with him. He is not a marketing person but a chemist and not a patient one, either.
Some people that have a negative opinion have never used the product or have used it for the incorrect purpose or have expected it to fix a mechanical problem. Other negative opinions come from those that know everything, even things that no one else knows.
Auto-Rx has had it's ups and downs with BITOG but all that has not been because of the quality of the actual product itself.
I actually administrated a wide scale test within a taxi fleet with excellent results. The mechanics did what the product was and they are the ones that measured and recorded the results.
One other thing about Auto-Rx. It's probably not required by many owner/drivers because they just don't keep their cars long enough and are not interested in doing something like maintenance doses just to keep their engine in better shape for the next owner.
If you have a sludge problem and Auto-Rx does not "fix" it then it was beyond the realm of help other than a mechanical repair. In other words, it's worth the expense and effort before tearing down or selling your ride.
My experience also; I've cleaned up a couple of used cars that I bought that hadn't had proper maintenance.
One example - over the 1500 mile treatment distance on one vehicle with ARX, the oil came out as black as I have ever seen it in any car before or since. I repeated the ARX and again it was very very dark. Subsequent short OCIs cleaned it up to the point that it barely darkened over a 3k OCI. So it seemed that it did some cleaning.
However to be fair, there's no data to compare vs short OCIs or any other additive. I'd use it again though, as it does not do harm to an engine.
Oh yeah and
for this statement, truer words have not been spoken:
