RE: Recommended Oil for CX-7
the manual says its 5W30.. Not sure about synthetics though, there is a thread regarding using synthetics in another CX7 forum www.mycx7.com

Best advice, IMO, is to not second guess the engine builders. Use what the manual says and change it religiously. They designed and built the engine and chose its components. They know best.

i would like to see this in ANY mazda service/owners manual. synthetic oil is WAAAY better for turbos than conventional.
