5w20
I just got my Overland back from the dealer after 10K service. They used 5W40 synthetic oil.
I asked why not 5W20 and they said they use 5W40 on all the Jeeps and that it was better anyway.
My question is this...I am sure I read that the MDS very specifically needs 5W20. How true is this and does anybody know of a specific instruction from Jeep to ONLY use this?
How do I convince them? Write to Jeep in the US and get them to send me something in writing maybe?
I don't even want to think about what they will use in the diff's, TC and transmission.
