Long time lurker first time poster.
My wife's CX-9 needed yet another warranty repair(not engine related) and I happened to kill time by talking to the parts guy. He was asking me about the car. I brought up oil.
I ad mentioned that I use PP with a Pureone filter. He told me that it was a bad idea to change oil yourself under warranty. He told me that in the last 4 years theyve had 4 blown cx-7 engines that were under warranty. The first question Mazda asked the dealer was whether there was a Mazda filter on the car. If the answer was no, or if there was an oil change sticker on the windshield, it was an automatic warranty rejection. I would venture to say that the oil and filter I use are superior to a Mazda filter and Dino but now im nervous that if something goes wrong with the motor id be sunk. Your thoughts are appreciated.
