Methanol is very corrosive - I dont know how it would do in a car with 10-20 year life, as opposed to a race car that may be torn down every 10 hours of use.I was waiting for someone to post something about what this stuff does to cars. Thanks.
As for laws requiring us to buy something: no thanks.
I've used it for years without any noticeable ill effects but methanol can be absorbed through the skin and is a cumulative poison.
That said, I repeat I have been around it for years without any noticeable ill effects. I have certainly gotten more of it on me than you would filling your tank. Certainly an alternative, but I would think that you couldn't very well switch back and forth to gasoline
