A Mazda 6 is a regular consumer car. Usually the only thing you need to do every 6 months is change the oil and filter and check fluids. Per https://www.mazdausa.com/siteassets/pdf/owners-optimized/2018/mzd6/2018-mazda6-scheduled-maintenance.pdf https://www.mazdausa.com/siteassets/pdf/owners-optimized/201... , the only thing you need to do every 6 months is change the oil and filter and check fluids, and lubricate the locks. Google says you can use conventional oil in a Mazda 6. Please elaborate what you mean by expensive six monthly service. Did your regular service visits include additional items? What and why? And how much did they cost? I am curious what makes Mazda 6 regular service more than other ICE cars.
