    Plus for some people saving $10 is important.

    Well, what're they doing buying a new car, then :confuse: ;) .

    Dealerships here are often (perhaps with a coupon) less expensive than independents or chains for oil changes.

    How un-American, jeffy!!! Credit is what makes this country great. :)

    Plus we wouldn't have forums like "I owe more then my car is worth....." on Edmunds if people listened to this advice. And that would just ruin all my fun.

    My Honda dealer charges me $10 to change the oil and filter. I provide the Mobil 1 oil and filter to the dealer. Oil is best changed hot and i'm not going to hurt myself for $10. " I love me some me." T.O.
  • What do you save by changing your own oil? Maybe $10 per change? I'd rather avoid the risk of a hassle, should a problem occur, and let the dealer do the changes.

    Sometimes it isn't about the money. I get personal satisfaction out of changing my own oil and filter. I know someone who's car recently threw a rod because the technician who changed the oil shorted the engine by several quarts.

    The old adage "If you want it done right, do it yourself" has some truth to it...as does "to each his own"

    Happy motoring, and "Zoom, zoom"!
  • After doing the rounds with Mazda and getting nowhere I fixed the car myself. It ended up being 2 spun rod bearings. The total fix cost me $75 and 3 hours work. Then I traded the pile of junk in. Even swap on a Dodge work truck with a lifetime powertrain warranty.

    I guess one more reason NOT to change the oil myself....

    I would have to sue myself in this scenario :sick:
  • I have a 2007 MAZDA 6 I bought new last spring. I have changed the oil 3 times since new and have 11,000 miles on the car. My 7th and last MAZDA. The engine went bad. Bad knocking. Without even looking at the inside of the engine Mazda refuses to honor the warranty because, GET THIS CRAP, they require the VIN number and milage to be on the Auto Zone receipts from when I bought the oil and filters! Who has that? I will send anyone who wants a copy of the letter of rejection from MAZDA NORTH AMERICA Inc.,
  • jeffyscottjeffyscott Posts: 3,855
    That stinks.

    I always use the dealer for oil changes during warranty, just to avoid any potential hassle in case of a problem, such as you are experiencing. For $20-25 per oil change, it is cheap "insurance".

    I haven't read the fine print in the manual but do you know if it says anything about doing that? If not, not how they expect you to document an oil change like that since it's over and above what the average person does when they get their oil changes. Most quick lubes put the license plate number on the reciept. Wouldn't that suffice?

    I would consider talking to a lawyer for an opinion, then checking out your states small claims process. Some states go up to $5000 for small claims which should more than cover a new engine.
  • Hi,

    I am in Quebec, and i scrap my engine because my filter cracked ouside. Mazda don't want to honnor my warany because i missed 2 the 2 last oil change.

    Is your situation as benn solved.

    do you have a copy of this letter of rejection.
  • I just bought a 2007 Mazda 6 5sp on July 30, 2007. I had 1 oil change at 5000 per the dealership. I had the dealership change the oil. At about 7000 heard a slight noice but I wasn't concerned. At 8500 it got loud as if I had bearings loose. The dealership told me told that the engine is bad (like your Mazda) and it is the 3rd engine they've seen so far w/this problem. They are concerned that this is turning into a epidemic and they are going to call Mazda. I don't know if this is going to help you but maybe this problem may be turning into a recall on their engines. They are going to replace my engine because it is under warranty and because I had my oil change done at the dealership.
  • jeffyscottjeffyscott Posts: 3,855
    Which engine is it, the V6 or the I4?
  • Thank you so much. I'll keep this for my suit.
  • You're welcome. Good luck. When I get my car back (hopefully this Friday) I'll let you know if I find anything else out.
  • I found out what happen to the engine today when I picked up my car...according to the dealership. They said the engine was down 3 quarts of oil, bits of metal in the oil BUT there wasn't any leaks or anything else wrong with the motor from what they can tell at the dealership. My oil light did not go on either to let me know I was low on oil and I was not due for oil change for another 2000 miles (they recommend every 5000 I go every 4000). They can't explain why this happened and they talked to Mazda and Mazda has no explanation for this either. The two previous Mazda that they replaced the motors on were Mazda 6's with the same motor as mine, I4, but they were automatics. One had 37k and one had 3500. When I was picking mine up they were in the process of replacing another motor in another Mazda (I don't know what type of Mazda I just saw in the shop and the service manager mentioned it to me). I hope this helps.
  • Greetings,

    I am sorry to hear about the engine problems here--hope you can resolve them satisfactorily.

    I have a 2006 Mazda6 S (V6) sedan, which I bought used about a year ago. With the recent cold weather, I have noticed a "burning" odor when using the HVAC to keep the car warm for periods of 45 minutes or more. The odor reminds me of burning oil, but there is no smoke and it doesn't appear that I am losing oil. The smell seems to come through the HVAC vents when the fan is on.

    Is this normal? Any recommendations to get the odor to go away?

    Thanks much!

  • sounds like a just a really lousy local dealer. I have been working for mazda as a tech for over 20 years and I have never heard of such a thing. My particular dealer I work for at present is too generous IMO. They give away engines like nobody's business. We have a car in the shop right now that has a cold air/aftermarket intake setup that sucked up water during recent rainstorm. The configuration of the intake was very low and made it easy for the water to get in. Physics took care of the rest.....
    Dont take NO for an answer- keep calling mazda. I have seen a few 2.3's launch for no apparent reason too.
  • Racefan and Femlawone, I own a '07 Mazda 6 and had a strikingly identical problem with my engine.

    In a nutshell: Days prior to taking the vehicle into the dealership to find out the source of the rattling noise, they (the dealership) had changed the oil and completed a routine general inspection of the vehicle without any issues. Two weeks later the rattling noise appeared. I took it into the dealership immediately to have the issue inspected. When I picked it up, they said they weren't sure what the source of the problem was. They told me they replaced a piece and that the warranty covered it. The problem seemed to dissapear, until somewhere between 3-5 thousand miles later the rattling noise came back. Ironically enough, a couple of days after the noise came back and I was on my way to the dealership to get an oil change and get the rattling noise looked into, the engine busted in the middle of the freeway! After it was towed away and inspected by a dealership, they told me it was missing oil. The service dept. said it was my fault, not theirs and that they would not cover the cost for an engine replacement. Mazda also disclaimed any fault.

    I am becoming aware of several other Mazda 6 owners who have had the same experience. Racefan, what are you currently doing to resolve your situation?

    I had no luck with the dealer or factory rep. I took it upon myself to fix the rod bearings that were damaged so that I could trade the car in and buy another vehicle. Total cost for the repair was around $70 And 4 hours labor. Hopefully this might be an option for you if the engine still runs.
  • jbahjbah Posts: 23
    Just to re-cap my situation. I did get a new engine out of mazda b/c 2 cylinders were showing a depreciation in compression. This was less than 40k miles. They wanted proof of my oil changes. Also, the clutch is making a strange noise again. This is after they replaced the clutch at 20k miles. I certainly wouldn't buy a mazda that is built in the US b/c the Japan versions didn't have these problems. I still feel like they should fix the clutch but I'm out of warranty and they already refused to honor anything else. They also had to fix the tranny mount and leaky axle seal after the engine swap. I don't know what to say really, other than MAZDA SUCKS. Thank G*($ though they honored repairs but why should you have to take in your brand new car five times a year for four years?!!?!?! :mad:
  • racefanf1racefanf1 Posts: 35
    I found a used motor (10k miles) for $1250.00 and paid a guy $1250.00 to install it. It cam out of an automatic and required a bit of conversion. All is fine now. I've had 7 Mazdas and no other problems ever. Mazda will never see my face again. No one should but a Mazda!!!!!!!

    Hi. Just curious. Is anyone involved in or aware of or planning on being involved in a suit against Mazda Corporation regarding the Mazda Speed 6? This corporation apparently honors nothing under the supposed warranty and they keep making us pay for the same repeatedly breaking part even though that part comes under warranty. I am very interested in suing Mazda and wanted to know if anyone is involved in a class action suit? Thanks!
  • racefanf1racefanf1 Posts: 35
    Hi, I do plan to sue Mazda as soon as I get all my information together. As-far-as a Class Action suit goes, I was involved in 2 of those before. One for $17 million against Coleco and one for $8 million against CitiCorp. I received $8.47 on the Coleco one and $1.52 on the Citi one. The lawyers got the rest. I would however be interested in all of us putting one letter of solidarity together to Mazda to see if that would help before I sue.
  • Mazda6owner:

    Make sure you keep detailed notes and dates of everything you did, who u spoke with, and what was done. I do every time I go into the dealership. I keep a log/diary on my computer, how many miles I drove between problems (as I had to bring mine back after the new engine was installed as they did a bad install, oil was leaking everywhere the next day) and keep every piece of paper the dealership gives me because if you go to court you can use it to refresh your memory.
  • i have a used 2003 mazda6. it was running great for the first month (i changes the oil then). but after three weeks the engine was making a knocking/rattling noise. i checked to see what it was and the oil was low. after changing the oil again the problem seemed to just get worse and now i have no car. i still dont know what is wrong but everyone is guessing the oxygen sensor is bad or the engine is going to die soon. any ideas on what the hecks going on with my car?
  • mz6greyghostmz6greyghost Posts: 1,230
    If it was the Oxygen sensor, fuel consumption usually goes up, not oil.

    My guess that it's a bad PCV valve. It's a common issue with the 3.0L V6.
