Update on my scenario.

Just installed a new set of tires (Turanza LS-Vs) in the 225/50 flavor (little wider than the stock 215s).

Same drive as before, but now my mileage has dipped to a little over 21mpg.

The EL42s I replaced were gone, so perhaps they helped the previous mileage I was seeing (closer to 23mpg).

The car definitely feels 'stuck' to the road now, whereas before it felt like I was riding on wagon wheels (fyi..EL42s are horrible tires compared to LS-Vs).

I have gotten more than 400 miles per tank on the highway! No big deal. We take a Florida trip from Texas every year. Drive from Houston to Destin. First fill up after Baton Rouge. Around 400 miles.

any updates you can provide? I'm in your same situation, actually I was getting an average of 17mpg, but every since my 60,000Km service (they've only changed the oil/filters and air filter, I've been getting low 16/high 15 mpg... I'm wondering maybe they've done something to my car cuz it is kinda odd... oh btw, in that same service, they've also changed the board that holds the defrost button on the consol...
