Hi all. I just purchased a 2009 Mazda 6 2.5l 6 speed manual transmission with 115,267 miles. The car runs great and the engine is so quiet. I am looking for advice on what would be the best motor oil, coolant and tranny fluid to use. I work at a CDJR and Mitsu dealer so I have techs to help me out. The car was a trade in at work. They had already done the LOF, exhaust, and Front brakes and rotors, before I purchased the car. Looking at a coolant flush to be done and the tranny fluid changed. Thank you for taking the time to read and respond.
