Using DFCO to increase your MPG

Big mistake there, Bailout. My home address is in Oklahoma. But I drive to New Mexico, and/or Colorado nearly weekly. In fact, I just got back from Grand Teton National Park, in northwestern Wyoming, just south of Yellowstone, a few days ago.

(Yes, I drive *quite* a lot.)

Nice try. But you really need to get out more before you counsel me upon "expanding horizons". I probably cover more ground in a month or two than you do in a year. And more varied (and mountainous) ground, at that.

So why don't you try addressing the facts I've presented rather than trying to sneak in a personal attack based upon your guess about my driving experience. I have made quite a number of factual points, in previous posts, which you seem set upon ignoring.

Look. DFCO is a handy tool in the tool chest. But you have overemphasized it in comparison to some of the other useful tools there. I like seeing 9999 on my Scangauge II as much as anyone. But even over extended DFCO periods, the effect needs to be kept in perspective. Because the Yaris engine easily uses 20 times its idle consumption just as soon as you start ascending the next hill.
