Since this is the MPG topic, I've moved the posts about buying a 2004 RX-8 to the general Mazda RX-8 topic. Just click the link to continue.

20 mile commute - 10 freeway, 10 city.
Was getting 16 to 17.5 (if staying in the right lane etc.)
Post Sep 08 reflash - dropped to 14.8 to 15.5 tops.
Agree, when you run this thing it drinks.
#92 of 96 RX-8 MPG vs Prius MPG!!!!! WHAT???
Feb 12, 2010 (7:53 am)
Ok, folks I know I'm entering the realm of fantasy, but please hear me out before any profanity leaves your lips.
So I'm in an argument with a Prius guy at work over the famous Top Gear BMW M3 vs Prius MPG episode where the Beamer got 19 MPG and the Prius got 17 MPG going around racing track.
My point to my friend at work is that my RX-8 AT, when driven at 85-95MPH in hard Boston Mass Pike commuter traffic where lots of paddle shifting and lane changing is required to stay moving, I've been achieving 20 MPG.
My friend contends that his Prius beats my 20MPG, but he can't produce any data from anywhere other than straight cruise control drives at high speed that show 25MPG over the 85-95MPH.
I'm pointing at the Top Gear shows results of 17MPG that the Prius got, as evidence that when you drive a Prius close to it's performance limits, that MPG drops below 20MPG.
Anyone got any racing or hard driving commuter data to point to? My MPG experience with my 2005 RX-8 AT is definitely a solid 20MPG when doing the fast hard driving 40 mile run from my place in western Mass into Boston, which takes me down 495 and then east onto the Mass Pike. Traffic moves out during my typical segments of the run. I go through two tolls where it's a freak'n drag race off the line most times and I get off at exit 17 before reaching the heaviest Boston traffic.

i think you could take any economy car with an automatic and demonstrate that, when flogged, it will get similar or worse mileage to a manual sports car keeping up with it in the highest gears possible.
#94 of 96 Horrible gas mileage
Jun 03, 2011 (12:10 pm)
I live in Canada and I own a 2004 Mazda six speed. I drive to kelowna twice a week which is around 120km (62 miles). My gas mileage is horrible, I am getting 19 liters (just over 5 galons) to 100km (74.5 miles) or 350km (218.5) to a tank. I dont think the car should be this bad on gas. What do you guys think? Plus when i go up hills the car smells terrible, not like suffer but like oil and gas mix. My engine light turned on for a week but turned off. Any suggestions

It sounds to me as if your catalytic convertor is failing, and I would suspect that your ignition coils may well be shot too. The mileage you are reporting sound like stop and go mileage, so if you are not doing a lot of idling whilst stuck in traffic, then I think you should definitely assume something is wrong. The fact that your CEL came on says something bad has happened and you need to know what error code was logged before you attempt any further diagnostics.
