Check out the above link ... very interesting! Any input?

Having worked with it for a few years, I know it will attack almost any kind of rubber and plastic. I don't think I would chance it in mine.

I tried it back in the spring. No significant difference on my truck.

i tried fingernail polish remover in my truck before and did notice an increase.... mabe 3-4 MPG but i was taking it alot easier since the price gouging has began......
