    Mazda3 HU Swap Help Requested

    Hi. I just purchased a used '07 Mazda3 Sport. It has the stock single-CD HU. I do not have Bose nor do I have the Trip Computer. I am thinking of upgrading to the 6-disk changer unit. Does anyone know if this is a plug-n-play swap? I also have found two part numbers for the 6-disk changer...

    2003 Mazda6 Checkup Suggestions

    Since the dealer couldn't even get the weight right, I am guessing they can't get the type right either. It is probably dino juice. If I get the car, I will probably update to the motorcraft, or go for Mobil 1 (assuming I can find the right weight). Now to get the thing to the (other) dealer for...

    2003 Mazda6 Checkup Suggestions

    Spoke to the dealer. Oil used is 5w-30. Not the recommended 5w-20, but still thin enought? Is it possible that is the problem, or can we rule that out now? -- Ian

    2003 Mazda6 Checkup Suggestions

    Oil changes done at dealer He has told me that all the oil changes were done at a local dealer (a different one from the one where I am going to have the checkup done). Do I need to check with them to ensure they used the right viscosity? Seems silly...

    Didn't I read the manual that it doesn't take premium? Or was that a mis-read? So it requires 92/93 octane?

    Roughness questions Now that is an interesting idea - you are scaring me. I don't have time for a UOA, but I have asked the current owner where he had his oil changes done and for the receipts. The roughness was not just a function of high RPM, but also while under load - which actually...

    Thanks for the link, crossbow. The car has been exclusively maintained at the dealer. I did not look at the oil viscosity that closely - I will check next chance I get. Is there a known issue with the computer on these cars? I certainly don't know if it has been reflashed, but as it is under...

    2003 Mazda6 Checkup Suggestions

    Good morning, all. I am looking at a 2003 Mazda6s (v6, sport package, 5-speed manual). Anything specific I should be looking for? Any known weak spots? Also - the car seems to have a little roughness through the upper rpm range under load. Is that normal? I drove a 2005 6s with automatic...

    Quick vid of my wife spinning out at an autocross..

    part of the reason I married my wife was when I told her about my hobbies (then SCCA ITB and autocross), she said "Who WOULDN'T like that?". Since then she is a multiple time regional AX champion (I had an AS car - I ran in SS locally and let her have the open AS class - which she won)...

    Mazda6 Autocross Info, Tips, Advice Needed

    Hey - is anyone out there autocrossing a Mazda6 in SCCA Autocrossing? I am about to purchase a 2003 Mazda6s (5-speed, of course), and am wondering if I am going to be the only one doing it. It is classed in GS against Mini Cooper S's, BMW 318i's and many others. I may not be competetive, but I...
