2 points. First, since the highway speed limit is often 65 mph I don't understand why driving a tankful at 65mph comes off as a "stunt". I'm not trying to be self-righteous about it; I go plenty fast sometimes but let's put it in perspective. Not only is it a legitimate test it could also be very useful information the day you hit that "Next Gas 110 miles" sign.
Second, the hype of the Renesis powerplant and part of the reason it won "International Engine of the Year Award", was due to the leap in efficiency projected over the previous rotaries. Weren't they claiming something like low-to-mid 30's highway mileage? So I think some people that started following the RX-8 story early on are legitimately wondering why the mileage is turning out to be half of projections. From an engineering viewpoint falling short that much is astounding.
I can live with the mileage but on a long trip I'd be just as happy cruising at a speed that gives significantly better mileage (if there is such a speed). People tend to overestimate the time savings they get from speeding. Also factor in the reduced frequency of fuel stops and how long it takes to deal with a speeding citation :p

Viking, thanks for reminding me. I really appreciate it. You've made everything so clear for me. Now, during my 2250 mile (one-way) long-distance trip, instead of cruising at 60 to 75 mph, I will accelerate and decelerate in WOT fashion. This will allow me to do brake testing as well as those 0 to 60 to 0 tests that some magazines do. The RX8 was truly made for a 2250 mile stop-and-go trip. I hope I won't get tired out in the first 1000 miles from this. Do you think playing Linkin Park and Limp Bizkit will get me pumped up for the physical and psychological demands? I just hope to God that I don't get an aneurysm going through west Texas. Don't worry. Whenever I feel like I can't take anymore of it, I'll remind myself that this is the way the RX8 was meant to be driven.

NO PEENISFELLOFF, Thanks for reminding me. I learned alot from you. I will be sure to make all my shifts at 3krpms or less, and NEVER drive more then 60-65mph down highway. DO YOU THINK PLAYING THE CARPENTERS OR POSSIBLY BARRY MANILOW WILL HELP ME DRIVE LIKE GRANDMA AND TRY AND SAVE GAS? And don't you worry, when some 75 year old in a plymouth horizon passes me, I'll remind myself that I am saving gas, and that I bought the right car for slow cruising. As long as I drive this car slow, and keep the rpms down, I'll believe I bought myself a decent gas mileage sports car. Whenever I get that feeling like I want to step on gas and accelerate fast, I'll just tell myself that YOU WILL NOT GET GOOD GAS MILEAGE IF YOU DO THAT, and I'll then slow down, crank up the carpenters and go back to my 60mph bliss.

I always hate ******** driving like morons reving in massive rush hour traffic. Driving like an *** up to my car then slamming on the brakes. Then they flash the lights, even tho there is no where to go and a thousand cars in front of me.

You lie again, steve. If you read that thread, you would have posted in that thread, not this one.
You have to find that thread first. Search "mileage long distance cruising." It is result #11 out of 12.
Oh and try not to lie anymore.

As a 3+ year owner of an RX-8, I think you can count me in the category of most owners; I don't stress out too much about the MPG.
Having said that, I would like to throw a little curve ball into the MPG discussion. I've noticed that the speedometer on my 8 is about 3 miles per hour optimistic at highway speeds. That's an inaccuracy of about 4 percent. Now, I haven't checked the accuracy of the odometer, but it's probably safe to assume that it is also optimistic by a similar amount.
So, when I think I'm getting 20 MPG, it's probably closer to 19 MPG. Not a huge difference, but in the wrong direction unfortunately. But again, I'm not going to stress out about it.

I'm totally down for seeing how long i can drive 55 without stopping for gas. I've done some very unscientific studies and found slowing from 70 to 55 makes a pretty significant difference.
Provided someone else pays for wasting 15 gallons of gas puttering along the highway.
