Just an aside, I drove from Topeka KS to OK City once, about 130-140 kph....
I left my gas cap in Topeka by accident.

Never caused a CEL.... and it didn't affect mileage, that trip is 475kms, I
only put in 8.5 gallons.

98 civic 5-spd, had about 165000 on it at the time, back in 2003.

This is a perfect complement to the monitor "readiness flags" issue.

If your MIL did not illuminate even with the gas cap off, then the ECM
never did its EVAP self-test. You would think it would have run a test
during such a long drive, but it did not.

This is why it is sometimes necessary to do the official "drive cycle" to
get all the self-tests to run so the monitors will all report "ready", and
why it's a bad idea to clear all the flags by disconnecting the battery.
