That is very helpful, thank you so much for sharing! I still have some doubts on the accuracy of these results though. I kinda doubt that other reputable products such as Star-Tron and Seafoam actually decreased the fuel's stability, a lot of people have reported success with these products. I also have a hard time believing that Seafoam caused so much corrosion on the steel rod, it's basically just diesel fuel, naphtha, and isopropyl alcohol. Neither diesel fuel nor naphtha is corrosive and the minuscule increase in the fuel's alcohol content from the ~10% isopropyl alcohol that Seafoam contains surely didn't cause that much corrosion. I also question why Sta-Bil Marine's results weren't included in the corrosion resistance test since it's supposedly so good at preventing corrosion. I also question how heating the fuel up to an unrealistically hot 212 degrees affects the results of these tests. I know that higher temps accelerate the degradation of the fuel, but I wonder if such a high temp might favor some products over others. If a product is designed to stabilize fuel up to the maximum temp that the fuel is expected to reach (maybe 140 degrees or so) and its heated to such an unrealistically high temp, maybe the active ingredients in some of the stabilizers broke down from the extreme heat. If so, this test says nothing about the real world performance of these products since the fuel will never get anywhere near that hot in the real world. Another significant factor they left out was whether the fuels were tested in sealed or open containers; this makes a huge difference as well. Judging by the results I presume the fuels were tested in open containers, but who knows. It would also be nice if they listed which "independent testing lab" did the tests. Was it a reputable lab? Was it a company they created? Who knows. And I know from past experiences to not expect a response from Golden Eagle if I contact them to ask questions, so that's nice. To be clear I don't dislike Sta-Bil, I think it's a good product. I have used it for years and I have never had a problem with fuel going bad in my equipment during storage and I plan to continue using the product in the future, I just question the accuracy of the results on their website and I don't like that the company is unresponsive to my emails, not good customer service.
