We say

Millers pretty much lives up to its cetane rating claims, but it offers no power or economy benefits. Some emissions fell, but not during urban use. This contrasts with a small increase in soot, but only under motorway conditions.

Is it worth it? No.

Can't say I am suprised by their findings....

fair enough, each to theyre own, i know mine responds far better than without it. i am the skeptical type and actually was given a little for a tankfull, after feeling the difference-particularly at start up- i have concluded that i will ALWAYS use the product. mpg hasnt necessRILY gone up persay but the better running is more than enough for me to want it.
