I too am disgusted with my gas mileage. I have a std 2004 and I'm getting 11.5-14mpg on mine. I've tried driving in different rpm ranges, with little or no change. I have had the car back to the dealership for service and received a flash upgrade on the computer and the new hot plugs, but no change. I also have oil that looks like yogurt! I've had them look at this as well and I was told it is normal, but that Mazda has recently come up with a "fix" just so owners won't be driven crazy by seeing foamy oil on the dipstick. It is some sort of tube that fits into the engine somewhere, somehow...I plan on being there to see this installed! If I can't find some owners who are getting at least 17mpg, I'm thinking of finding an attorney who will file a class-action suit.

What are your damages? A couple of gallons a gas per week? $4 a week maybe? Is it not really more of an annoyance than something that requires a huge lawsuit?
Will an attorney actually take a class action suit from the seven people in the country who bought a rotary without realizing that they get bad mileage? The last RX7 was not known for its reliability or fuel mileage. In fact, rotary mileage has always been pretty miserable. Poor reliability and fuel mileage almost did in the rotary back in the 70s. The reliability has gotten better, but not the fuel mileage. How much of an increase in fuel economy do you expect out of that dirty little power keg of an engine as its output has nearly tripled over the years?
Not to be mean, but maybe you should just suck it up and buy a Civic and get 30mpg. Or you could just realize you have a really cool car and enjoy it.

The class-action suit would have to be against the EPA, since they are the ones who came up with the estimated mileage numbers on the car's window sticker. And all I can say is "good luck suing them." Of course, if you read that sticker, they have already covered themselves by stating that your real-world results may differ from those estimates.

"Thanks" for your replies, guys. I did further reading of the postings on this site...actually got thru the first ten pages last night, I'll withdraw my comments about a class-action suit, however, you cannot tell me 11.5 mpg vs. 18 is just a few gallons per week. As a matter-of-fact, it adds up to $20 per week! Don't get me wrong, I do love the car, I read the complaints about mileage on RX sites before buying, but 11.5! The reason I posted to this site was because I have spoken with, and seen postings on this site of owners claiming 18-21mpg. All I want to know is why not me? Is there something wrong with my car. If there is, I want it fixed, or one that works properly, I don't want to go buy a Civic! Many of the postings on this site are helpful, and that is what I was looking for, but comments like, "go buy a Civic" are just stupid. enuff on that subject.
ALSO, can anyone give some insight into the Yogurt on the dipstick issue? I'm assuming that could be part of the mileage issue. I have 2400 miles on the car in 9 weeks, and I'm not talking air bubbles in the oil, I'm talking YO-GURT! Anyone know anything about the "fix" i mentioned being told by my tech? I appreciate any HELPFUL responses. Sorry if I hit a sensitive nerve with rotary-engine buffs and the gas mileage thing! - Rick
#680 of 1414 11.5 is the worst I have heard of

I drove an automatic for about a month and averaged a little over 14 mpg. It is my father-in-law's car. He says the mileage has improved over time. He gets around 17 mpg now.
Maybe the engine has to loosen up a little.

I have had three RX8's they all averaged between 17 and 20 mpg. Not great but I can live with it. Of course if I push it or get stuck in bumper to bumper traffic mileage does drop like a stone. 11.5 certainly sounds unreasonable. Try turning off the traction control after you start and see what happens. I noticed an increase in mileage doing this. I am curious on the yogurt dipstick comments. Condensation causes the dip stick to get foamy but it usually does not impact the viscosity of the oil. Are you telling me if you drained the oil it would be thick like yogurt? I am curious. Also I saw someone mention a fix to the foamy dipstick issue. If anyone knows of the tech issuance that covers it, I would appreciate a post. Good luck with your problems. Let me know the answer on the yogurt thing.

my best suggestion is to try a different dealer. You will most likely get a different response. If it is as bad as you are stating (both mileage and the yogurt comment), I would have to think something is wrong.

Everyone on this board is whining abut their RX8's gas mileage, but for a dose of reality, read the following news item from MSNBC:
See? EVERYONE is complaining about the EPA's testing method. For instance a BMW Z4 has a sticker mileage of 21/29 and a real-world mileage of 14. My suggestion is that you enjoy the car and leave your calculator at home when you go to the gas station!
#685 of 1414 RX8 Starting Problems
Mar 10, 2005 (5:02 am)
I have a six month old RX8 in the UK that has now been back to the garage 4 times with the same problems. The car from time to time refuses to start. This is not exclusively in cold weather. Mazda say they have run all the tests they can and find nothing wrong with the car. It has had all the upgrades currently avaliable. They also give me the impression that no one else has had this issue and I must be pumping gasm which i am not. Has anyone else encountered this issues? Thanks
