Can someone post what the US manual says about what weight oil to use in the car? (recommended and alternate viscosities)
I run 15w-40 Delvac diesel oil in my turbo Cordia, mainly for the higher zinc content and the ability to handle the older style turbo (TD05-16G) since it is an older engine.
I have been using 5w-20 synthetic Mobile 1 (recommended) in my Outlander since new and it has 96000 miles on it with no issues.
