My Mazda dealer did "synthetic" for $60 with tax and fees. This dealer I believe only offers synthetic oil. I don't know what kind. (Tampa, FL)
At Tires Plus I pay $70 for full synthetic with free tire rotation. This is where I normally go. They also offer lifetime alignment vs the dealer that wanted $180 for one alignment.
Mazda dealer also wanted $25 per wiper blade! They would not sell me just the inserts. So I just replaced the full wipers with this off Amazon: https://www.amazon.com/gp/product/B07DRP8MS4
