Anyone else think that this is the case, because I'd been getting barely 17 for the entire summer and the last two weeks (driving w/ AC off 80% of the time), it now is a little over 18? (12v fwd, manual). I'm in Houston, and really have only been driving in the morning to work (cool still) or in the evening (no sun)--this is about as early in the year that AC can be turned off here.

Three things happening:<p>Engine now has 6700 mi....may be broken in better.<p>A/C being used MUCH less<p>Switched from Texaco premium to Shell premium at 5000mi...dunno if this was a factor.<p>I really like the extra 3mpg so I am not going to be picky & fool around to find what did what...I'll just enjoy my newfound "economy!" :)<br>steve

In Fact, haven't tried it without the A/C.<p>Doug

Steve,<p>Luxury and Sport if you want it to be........the only combo that would beat that is the (hopefully) coming V8 A6. That'll have more luxury AND it'll be quicker.<p>BTW, you simply have to get an ECU chip for your car! With the FWD Tip, the chip makes me as fast, if not faster than a manual from 0-60. On the highway, there are very few sports sedans (except the BMW 540i and the M3) that can overtake me.<p>Rick<br>
