Motor Oil for 2012 Mazda 3 (skyactiv)

Mazda recommends a synthetic 0-20 weight oil for this Mazda 3. Love this car's mileage and good handling. Oil changes
will now cost about $75 every 5,000 miles, according to the dealership's service department. Is there a 0-20 weight, quality
conventional oil or are there other alternatives to using this higher priced lubricant? Dealership says this lubricant and skyactiv
technology in the engine (higher compression ratio) contribute to the high gas mileage (about 40 mpg on hwy and 33.5 mpg combined
city and hwy driving). Anyone have some thoughts on this? Thanks.
