my oils been running thin lately and everytime i get an oil change its the same thing b.c i go to ford and they only use motorcraft so i was thinking about switching to royal purple but it goes 10w30 and up so does anyone have any ideas???
only use the oil your manual says to which is 5W30 or 10W30....i know Ford revised it, but if youve always used 5W30...the switch to 10W30 is not gonna be noticable.
