First oil change!

Took it to Countryside Mazda fir its first oil change under my ownership. i bought the car with 500 miles and today it has 1082 The dealer i bought it from told me they changed the oil but i don’t know what they used so I’m having Mazda do fully synthetic 0-20W Yay! They also did a full inspection and everything checked out. I got a great deal on a great car!
