Here's all the data I have. I sorted by transmission, then engine type,
then mileage. If your data are on this page and you are Canadian, please
advise whether you submitted US gallons or CDN gallons. You may need to
set your email client to use a fixed-width font for this to display
meaningfully.

The only thing that is obvious to me is that my van has the worst
mileage of all. Compression and O2 sensor checking are next.
