First of all I would like to introduce myself to the board. Hi y'all.

I would need some help on another vehicle in order to pass an emission test. I was told that a mixture of 25% alcool and 75% premium fuel would significantly help to reduce emissions. Does this make sense? What I don't know is if this alcool is Isopropyl (99%) or methyl hydrate.

The vehicle in question is 5 years old and supercharged. I want to make sure that this mixture does not harm it. Does the alcool increase or reduce octane levels. That's important on a supercharged vehicle. This is a one shot thing just to be able to pass the emission test. can I go as high as 50:50?

Many thanks,
