Are there any published ratings of fuel stablizers & ethanol remedy products other than the ones that tout certain products?


Not easy to figure out and all contain proprietary ingredients.

Saw this at one site:

Presence of ethanol complicates the product as it adds a separation
problem. Otherwise I would expect antioxidants and metal sequestering
agents to be the main ingredients.
BHT is a very common component of many "fuel stabilizers" in the
past.
