Because the implied claims I saw for great fuel economy on the Thermo-Tec box in the Autozone seemed misleading. Unicorns often exaggerate plausible results for marketing advantage, like a horse with a horn, or that can sprout wings and fly! But maybe this thread should be moved by moderators. I'd support that.

Agreed. And so, the questions. Thanks.

I didn't. It's about appearance. Only top side is painted. Why worse?

And thanks for the link. The civic has a cover, but I would bet it could be improved.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
