Hi guys, not sure if this is the right section, but couldn't find too much in the search section.

anyways.

i'm curious to know if anyone here uses water/meth injection?
i'm thinking about it, not really for the performance gains (would be a bonus though) but for milage and cost

is the an decrease in L/100km?

if so, is the cost of the water/meth and fuel used cheaper in general than just using fuel?

and how much water/meth do you go through?

Thanks
