Hate to crap in yer Wheaties bowl, and again, just how I've come to see things, but after looking at my car's MPG over time, I now think unless you get a 10% or more bump over a large period of time, it sort of gets lost in the noise to say that any 1 change is going to be a significant difference.

There are just so many variables to what we get with our mileage that it is tough to say that this or that alone made the change.

Doesn't mean you're wrong, but it still is only half a chance of being significant to me to be able to say "This for sure improved my mileage"
