I am a little confused. At Premium 30K, there are a number of 'Replace' items on the list. For example, 'Replace differential oil'. I am going to follow Schedule 1 but I only see 'Inspect differential oil'. If I follow Sch 1 thru 112,500, there is no mention of Replace. Does this fluid need to be replaced or just topped off?

 

I asked my dealer the saem, the answer I got is that they will check IF it needs to be replaced and then make a decission ....

 

I replaced my differential fluid a while ago. It is my understanding that this fluid needs to be replaced every 30K miles or 2 years, whichever comes first.
