My 2012 is still covered by the warranty,and to maintain the warranty Mazda wants me to change the oil every 8000km or EVERY 4 MONTHS !!! 3 times a year use it or not !!! Thats ridiculous, imagine my cars will get an oil change tomorrow and I will put it in the garage until the month of april, or maybe May. Tell me do I have to change the brand new oil ? I'm not cheap but throwing 30.00 down the drain ...you know what I mean. Do you think that Mazda can seriously think that they can deny warranty coverage if I decide to ignore the time limit and if I go with milleage only or 1 year interval ? before you ask this car doesn't make many short trip in summer, its usually 3/4 hrs ride.
