Nope ... but that's not a terrible idea.
Replaced the plugs and fuel filter.
Installed an UltraGauge and started hypermiling.
I began fuel logging in mid-August with a base tank average of 16.3 (EPA combined average is 16). After relearning how to drive I've improved by 10 MPG on my best effort in 2 months and saved approximately $193 in fuel costs so far.
