I have a CX-7 w/2.3l turbo and just started using M1 0W30. It seems to work great with the turbo. Almost 3K on oil and has not used a drop. I will go to 6k OCI. I have used M1 on various vehicles for over 15 years and am very satisfied with it. I'm sure most top name oils are good, but M1 is usually the best price in my area so I will stick with it.
