I don't know if I'd say EPA estimations are high, it varies a bit. I've driven a '94 Accord on a trip and it got 28mpg. I pulled 30mpg out of an '89 Delta 88 with a 3.8. It's all about the miles you drive. The Accord is taching almost 3 grand when the Delta 88 is around 2000 in overdrive. In the city the Accord would probably still be in the mid 20s and the Delta would drop to around 20. That's why C5's do so great on the highway, the .5 6th gear keeps them around 2000rpms at, what 75mph or so? That said, I drive mostly highway miles (sometimes 500-600 a week) and I got 29mpg on 3 straight tanks (shifting around 2500 most of the time) in my '82 ZX (n/a) this past fall. I've never got less than 23mpg, even layin rubber. I love the 21 gallon tank, I've topped 525 miles on a tank once, and over 500 another time.
