Is it another myth?
I read somewhere that unlike other cars, the mileage for an RX-8 is the same whether driving at 55mph or 85 mph. Is this true? There are so many myths out there that it makes me think this one is. After all, I have met folks with over 80K on their original engine who have never used pre-mix or the fancy oil and filter brands recommended on this list, never "redline each day" or ever redlined there cars and are happy as hell. They like the handling and they like the looks and can afford the low mileage around 16 that they get.

red line a day is fact
5w20 is garbage is also fact
they don't feel there is a problem cuz either they are retarded, or its just degrading slowly. I didn't know my engine failed compression if I never ask for it. does that mean it works? sure. ideal? far from it
people who has cancer usually feel fine and seems happy until one day they just fall down. hope that example gives ya a better idea

How do you average 20+? I can only do that when I am drafting behind a truck or SUV. At a steady 70mph, highway only, I get 20-21 and in pure city driving each day 2-3 miles one way, I get 13+ and in combination, 50/50 about 16+. I have a 2009 GT.

I would rather feel fine and one day, when I am 90 just fall down than to be told I have cancer, get radiation and chemo, go broke paying medical bills and still die young. All the folks do is get to spend a lot of money for no reason.

My replacement engine has averaged almost 21 mpg over 10,000 miles. Same commute, same driving style. It gets 24 on highway trips.
So I'm guessing it's not ALL driving style, different engines act differently too.

My daily commute is 75 mph round trip, 90% hwy. I cruise at 65 mph and I get 22-23. It is attainable, just use cruise control more

nah...correct me if I'm wrong but the most common reason for engine failure is low compression not abnormal bearing wear (which is what 5w20 would be responsible for)
I think what people mean with statements like that is that the RX-8 has poor fuel across the board regardless.
So you might as well drive the car hard since driving like a granny doesn't seem to save much gas anyway.

the interesting one was my 79 Rx7, we drove it to sevenstock twice, which is a 1000 mile round trip, and that car gets it best mileage between 3500-4000rpms, in 4th this is 60-65mphish, and in 5th its about 75-80mph. if you run it over 4000, mileage drops quite a bit. under 3500 mileage also drops, not by a lot, but it does. the sevenstock trips it was doing 23-24mpg.
i agree, it seems like the people with the most engine trouble are on this forum. my friend bought one of the first Rx8's, and its been nearly trouble free this whole time. its got something like 85k on it, factory engine, coils, etc etc. its due for some work, but what other car can you drive 90,000 miles without even doing the services?
i don't think you need to redline the engine each day, but i do think its a good idea to run it high enough so that all the valves in the intake operate. 5w-20 oil is fine for a street car. its too thin on the racetrack, but that's not where we are.
the handling is the best part of the car, its an amazing chassis. its so natural, has no vices, and it rides well too.
i just bought one, and i'm still pinching myself, its an amazing car.

and it's known fact it's very , I mean VERY EASY to mess up a "supposed to be easy" Rotary Engine rebuild.
people who decided their RX8 need to be driven at high RPM with pre-mix and expensive oils and more and then the old librarian where I work is at 81K (lots of folks redlined and lost their engines), still delighted with her RX8.
and location, quality of gas, driving habits, LUCK, etc. ALL matters.

it does effect engine life, try to run an engine with worn out bearings, and you will know.

when they really got the car other than rx8, they still get the 13mpg that they said "rx8" gets, but hey, they just gonna say they are lucky they got that car cuz in Rx8 they will probably get 8 mpg, makes them feel they made the "wise" investment.

the mileage really doesn't seem to vary much between 55 and 70 (i've never tried faster). i've had a ton of different Rx7's, and those exhibit the same behavior, i think you can attribute this to the good aero, the low friction of the engine, and then the engine is geared to be in its efficiency range right in the 55-70 area.

230 mile round trip to my mothers. Cruise control on at 60, 21 mpg. On the way back cruise control set to 80 (speed limit 75) 20 mpg. This is based on refilling the tank until it stops and with the help of fuelly. Filled up when I left and filled up before I left on the return trip. So go figure. Every other car I own as speed increases mpg decrease.

In general, I agree with you. However I can't use that as justification for closing it.
Mileage is indeed a mythical beast. Some are in full belief of what is possible, others are in full believe of what is impossible, and the only people that are willing to swing from one to the other are usually not doing their research. I will avoid using the term 'gullible'.
