I just got my Raptor and the oil & filter to change the oil so this thread caught my attention. I read the manual a few times and it never does "clearly" say to pour oil directly into the crankcase.
The two are called Engine oil filler cap (The one with the dipstick) and Crankcase engine oil filler cap.
But I do notice they vary a little on the exact wording at times if you you read the steps carefully. So that may be where the confusion is.
12) Install the engine oil filler cap, and the tighten it to the specified torque.
(Notice it didn't say Crankcase engine oil filler cap)
13) It states "Pour only 1.37US qt of the specified amount of the recommended engine oil through the engine oil tank filler hole"
(Now since the tank is referenced it must mean the one with the dipstick attached)
