Introduction:
I temporarily traded cars with my Wife, who drives a lot more than I do (I'm home-based with a lower average miles/month on personal vehicles). This leaves me with the Integra or '06 TSX. If I need the car-seat I have to take the TSX to my local work location.

The Vehicle:
For a "near-luxury" compact/mid-sized sedan, the TSX was actually designed with economy and emissions in mind.

*Drag Co-Efficient of 0.27 (one of the lowest for '06)
*i-VTEC system, lowers emissions at idle
*Retains 4-cylinder engine for lighter weight
*Manu-matic "Sport Shift" offers more control over the transmission.

The Problem:
Over time, something has sapped FE. It used to pull-down low-to-mid 30's mixed average, but these days, we're lucky to get mid-to-high 20's.

Suspects:
*Foolishly replaced the front tires with higher rolling resistance "cheaper" alternatives
*Front partial undertray has deformed under heat, which has dropped into the wind-stream.
*It says "Premium Fuel Required", but...

Investigation/Advice/Preventative
Ok, back to the title of the thread. We're running at 75K miles with a recent quick change of the transmission fluid. New tires are coming up and the undertray is what it is. Oil changes at required intervals, Seafoam cleansing regularly (crank, tank, and brake booster line -- the neighbors love that one).

What I don't get -- no tune-ups for "100K miles". Is this typically the case, for real? If so, should I replace the plugs and packs sooner?

Premium Fuel -- I've given-up on the argument and run either mid-grade or premium. 87-Octane seems to elicit pinging.

Any recommendations?

Thanks Folks...
