I keep track of everything myself.

That's fine, we don't have to call it a mild hybrid. But whatever you want to call it, it's working really well on my car. It only has about 7k miles on it, but the efficiency keeps getting better as it breaks-in. I have to imagine that this is probably as good as it will get.

Let me ask you something, though: if I went back and edited the original post to say 30 mpg, would you agree that how someone drives makes a huge difference in their fuel costs. Because that was my main point :)
