I noticed something interesting about the Gumout all in one at my local Meijer earlier. The bottle labeled with a "10146" date code was much darker than the same UPC "12192" bottle. I am assuming this is the year followed by the day of the year code based on the new bottles of Regane showing "14071".

So the darkest of all the bottles is the All in One 2010. Possible formula cost savings between 2010-2012?

First Picture shows the 2012 all in one on the far left, with the all in one 2010 in the middle, and regane high mileage with a 2013 code all the way on the right. The Regane 2012 looks almost identical to the all in one 2012.

Same shot with bottles turned for better clarity. Ancient bottle of lucas far left.

This 4 bottle lineup shows the cheaper regane "NON HM" fuel system cleaner all the way to the right. It is even lighter than the 3.

And a final picture to show them all nice and lined up in order of price and potency. (Sorry didn't focus well - these are all my HTC One M7)

Now i believe the darker the color in the bottle the more potent the formula, so of course i bought the all in one 2010 bottle, and i checked there was only 1 more buried way in the back. The bottle is a little warped but only 1 tiny little black spot of settling at the bottom of the bottle, the same as the all in one 2012.

Of course i overthink everything, but just sharing my thoughts!
