REFLECTOR: Auto engine installed 172

[Erik Franks]

Geared Drives suggests that if you use any avgas to change your O2 sensor
every 100 hours. They state that they haven't had an O2 sensor go bad but as
preventative maintenance to replace it. There's a check engine light in the
cabin to let you know if there's any issue including a bad O2. They state
that the only indication of a fouled O2 is higher than average fuel
consumption due to the fall back mapping.
The ECU is great for hot starts and starting every time. You just hit the
button and bam, beautiful airplane noise.
