I don't think Seafoam has any properties that would help with Ethonal water absorbsion, but we don't have a lot of experience with the product in our neck of the woods.
Why should you use a stabalizer product? Well, we figure that our customers have spent far in excess of $50,000 this year in ethonal related repairs and engine failures. We will not be surprised if that number reaches $100,000 by year's end. :x
So you can spend an extra $10 a tank, just in case, or take your chances. I guess you just have to ask youself this one thing- do I feel lucky. Well, do you? :wink:
Ethonal is evil stuff :evil: , and has no business being in gasoline.
