I dont know if this is all that correct...

For example it says that the engine holds 6.1qts of oil... ? (with filter).

Correct me if im wrong but I thought that the engine held 8 to 8.5 qts... ?

Oh, and by the way, do non supercharged xf's have map sensors? (it says on this manual but I havent been able to locate it in the engine... ?)
