Does anyone know what is the true oil change interval for a 2012 Mazda5? The reason I asked this is because according to my owners manual, I selected schedule 1 which says to have the oil change service every 7500 miles. Well as my car was approaching its 3000th mile, I got a call from the dealer that said I must have the oil change done or else the car will lose its warranty. I told them that I selected "schedule 1" but was told the manual was incorrect. After about 3 phone calls, I decided to take my car in for the service at about 7000 miles. Well, after I got the car back, the invoice stated that I got a "5000 mile oil service" and that my oil service should be done every 5000 miles. Is there something wrong with all the 2012 Mazda5 owners manuals? Is there something "fishy" about the dealer? What is the true oil change interval that you all use: 3000, 5000, or 7500 (which is schedule 1 that I use). Something is not right here...(dunno)
