 If they give you an option between synthetic or just a standard oil, a lot of them are requiring synthetic now with the turbos, especially the small four cylinders like that because all the heat generated and things in the bearings. But, yeah, I would definitely want to narrow that down. And the reason for that is the small oil passages, the big ones are fine on the bearings and things. But when you get into the small oil passages, they just can't oil the timing chains. They get damaged.
