Here's one for you. I have a 05 Audi A4 and the wife wants to go green but I want to stay with the Audi. I understand that water injection will give a cleaner burn in the combustion chamber so that would help. Now what about the fact can I run the car (which requires 93 octane) on regular unleaded? From my understanding W/I mix will boost the octane of the fuel and prevent engine knock. I know this is a totally against the grain of this forum, but I am looking at this as a possible use for better fuel cost and a cleaner running car. Thanks .

Thats not against anything alcohol injection reduces emissions, the lack of carbon build up in the engine shows that point, It really helps turbo diesels, But if you use a 40/60 mix of just good old washer fluid and use 87 octane you will still have around a 99 octane level you can go as low as 20/80 and still be way above 92 octane. Not to mention the car runs cleaner.

Why pay for premium when you don't have to, the kit will pay for itself with fuel saving and reduced internal engine wear , most people also notice a lower engine operating temps as well. There are no downsides to alcohol injection, and Turbo cars boost up quicker with less throttle just one of the many things you notice that is different. And a Audi are a snap to install a kit on.
