Update: Washed two medium-sized loads of bath towels; one with an original Tide Pod and the second with a Tide Turbo Pod. I checked each load about 15 minutes into an 18-minute wash tumble, then again during the final (2nd rinse). Note: Softened water.
1. Load One: The original Tide Pod behaved as expected. Sudsy wash, tenacious suds. Some suds left in 2nd rinse (normal in softened water).
2. Load Two: The Turbo Pod filled three-quarters of the tub with suds. I watched the final couple minutes of the wash, figuring the Frigidaire would kick into its excess suds protocol. While hanging up some shirts---three minutes, tops---the washer drained and began its balancing act. I hit the light button and to my absolute astonishment, the excess suds had disappeared. Again, the tub had been nearly filled with thick suds only minutes earlier. I've never seen that much suds just vanish. No oversudsing routine needed. First and second rinses had a bit of suds, but less than with the original Pod. Interestingly, towels felt well-rinsed when pulled from the washer after the final spin. No feel or sound of embedded suds.
Conclusion: The wizards at P&G have done something with the formula. Exactly what that is, I do not know. I wouldn't call the Turbo Pod low-sudsing (as does P&G), but it certainly gets rid of its suds very efficiently compared to the original Pod. Wild.[this post was last edited: 2/18/2015-18:55]
