I just took a long early morning trip and turned around and came back with the a/c on most of the time. I had the cruse control on 55mph most of the time and the fuel lite came on at 398 miles. I pulled into a gas-station, I was pleasently shocked $2.95, best price I've seen in months. It took 13.5 gal so my new best is 29.5mpg, bettered all previous seven rotarys and more HP too.

You can't measure MPG by tank full.
Must be a lot of Math flinkies on this site.

People who give "I regularly do XXX miles per tank" are giving useless info (we need MPG info, people!), but someone like oldrotor who gives miles on a tank AND gallons consumed is helpful.
Nearly 400mi on 13.5gals? THAT is impressive.

Car is in the garage now with 200.8 miles on trip and just below the 1/2 way mark. So theroretically I could get 200 more miles but not likely.

On a side note, how far can you generally drive once the warning light comes on. Or for you science guys, how many gallons are left once the light comes on?
That's about 20.9mpg, btw, on your 309mi tank.

^^yeah what he said...the fact that my car in everyday driving does 13mpg and in pure highway driving at 70mph can do nearly 24mpg just says something about my driving style...i have fun with my toys.

Riddle me this. I am in an '04 6spd, and I am getting nowhere near 310 miles to a tank. Possibly because of traffic while going to work, but I try to avoid it at all cost and keep it in 6th most of the time. I am using synthetic oil and 93 octane. Any ideas on why I am getting 230-240 miles to the tank? Fill me in PLEASE!!!

Dammit, these "XXX miles per tank" isn't helping here, people. We don't all fill up at exactly the same point. Keep your receipts and write down your mileage. Takes just a few seconds.
FWIW, on my last fillup I did 14mpg more or less on the nose. That is ALL "around town" stuff, never turning a wheel on a road with a speed limit over 45mph (though maybe did a little more than 45mph on occasion, har har har). 183mi, 13.1gals. Filled up a li'l early 'cuz I was going on a highway trip.
But there's my point about miles per tank. I can say "hey, I only got 180 miles on my last tank! Jeez!", but that doesn't tell anyone whether I tanked up with 13gals or 15 gals. That makes a big difference in terms of the actual MPG... I actually did 14 (poor), where at 15gals it'd be 12.2 (really poor), or at 15.5gals it'd be 11.8 (really, REALLY poor).
The difference between around-town and steady highway speed is quite remarkable. On the highway I'm getting 70% better mileage than in-town, which is a greater spread than I would've imagined. I can get the EPA number on the highway, but not even close in town.

I would go even further and say that any "xx percent city, yy percent highway", or "mostly highway", etc. is all but useless as well. Everyone's city and definition of city driving is different. The RX-8 sucks fuel at idle. Variations in actual "city driving" conditions will make a big difference.
You want a benchmark to compare mileage, try a highway run with little or no traffic, cruise control, at the speed limit, without significant wind or elevation changes. Anything else introduces too many variables and subjective interpretation, unless you've got a dyno set up with the EPA test routines.

I just returned from a several day trip through Northcentral New Mexico and Westcentral Colorado where I got 27.43 mpg on the first tank. Speed for this tank were 65-68. Later, on the return to New Mexico via the Interstate where speed was 75-80, average was 24.07. A/C was used about 50% of the time for all travel. Lowest mileage experienced, during a day of mostly highway but some city driving in Colorado Springs, was 23.65.
