I will make this post very short and to the point.
Sticker milage states 25city and 30hwy as this car is an automatic. The car currently has 20K miles on it and has gotten poor mileage from the get-go. The city mileage ranges from 19mpg-20.5mpg on average and the highway mileage ranges from 22.5mpg-24.5mpg. Gem Mazda in Tallahassee has tried to tell me the mileage values on the sticker are not generated by Mazda, but by the EPA and may not reflect what we should be getting. However, if you go to
FUELECONOMY.GOV
it clearly states the numbers are generated by Mazda on pre-production prototypes and the EPA only reverify's 10% of all models. I then called Mazda Custom Service at 12K miles in an attempt to get this issue fixed. I was told my local dealer would contact me to make an appointment. That never happened, but what did happen was Gem Mazda in Tallahassee closed out my service request from Mazda Customer Service stating they examined my car and found nothing to be wrong. That is funny, you examined my car without calling me and without my car being at your dealership. Yes folks, Gem Mazda of Tallahassee lied to Mazda Corporate regarding my car. Mazda Customer service then set up an appointment for me to actually take my car to Gem Mazda Tallahassee to have it evaluated. Before taking the car in I took several high-resolution pictures of the spark plugs which were all carbon'd and all showed signs of pinging and detonation. The pics are below. You will notice the excessive carbon buildup, but more importantly the little metal specs everywhere and the peppering on the porcelain which are all signs the car is pinging and detonating at some point within the engine map. So after the car is diagnosed they can find nothing wrong, yet they agree to replace my spark plugs. When I pick up the car I ask to see the plugs and guess what? There are no signs of any pinging or detonation on the plugs. Wow, Mazda now buys self cleaning plugs. I then produce the high resolution pictures of the plugs 8miles previous and they cannot explain why there is a difference. Guess what, 30 miles on the new plugs has generated the same excessive carbon buildup. Without getting into all the details they top it off by stating this on my invoice, "FRONT TIRES WEAR POSSIBLE AGRESSIVE DRIVING." The tires have 20K miles on them of course they have wear. BTW, they are worn more on the inside of the tire which suggest a possible need to adjust the camber. This is my wife's car who drives around my 2yr old daughter and 2month old son. I will never buy a Mazda again at this point! Buy hey, ZOOM ZOOM ZOOM!

I understand what you meant and yes we change our oil at the proper intervals. I have never met Bubba, but I typically purchase BP or Chevron. This car has never exceeded 25mpg on the highway and that is with the cruise control on. As far as our plugs looking the same, the carbon buildup may be a common denominator as most cars start rich to light the cat(emmissions) and then quickly run lean for economy, but their is no excuse to see signs of pinging or detonation on the plugs. Since the plug change I filled up with 89 octane and will record the city mileage come next fillup. As stated previously the car belongs to my wife and the answer to #1 and #2 is no and I checked the filter last week and it was not excessively dirty. However, I will change it to something less restrictive such as the K&N. I greatly appreciate everyones response and I will keep you updated. I am happy to see atleast someone is getting decent gas mileage with this car.
