Hi, I am looking for oil recommendation for 2008 Mazda 3 S with 2.3 engine and 5 speed automatic transmission. The car has 98k miles, I bought the car with 93000 miles and changed the oil right away with Castrol Edge 5w-20 (it was on sale) and WIX filter. I have been thinking about Mobil 1 0w-20 or 30 since I've had good results with it in the past in my 2000 Miata. Thanks!
