Oil and filter change video
 

First oil change, done. Easy peasy, dare I say fun, like my LR4 was. I put together a video:

Thank you so much Umberto, this is fantastic! I agree with your choice of oil. We were all confident in using Mobil 1 in the LR4 (Ford) engine, but we don't know what to expect from the new Ingenium engines.

Moderator - please move this very helpful thread to the sticky section.

Great video, Thank you!

Umberto, how many miles on your Defender when you did the first oil change? I was thinking an oil change every 7000 miles is the way to go.

8300 miles. I tried for 7500 which has always been my schedule in the past (with the LR4), but sourcing the correct oil and filter this first time turned out to be more challenging than I thought. Won't happen again. :)

Here's what I got from Castrol today. Look like we can use Castrol Edge 0w20 Synthetic. The one that come in the black bottle.

Castrol EDGE Professional EC 0W-20 replaces Castrol EDGE Professional E 0W-20.
​
Castrol EDGE Professional EC 0W-20 combines the cold climate performance of Castrol EDGE Professional E 0W-20 (STJLR.51.5122 oil spec) and the fuel economy of Castrol EDGE Professional E C5 0W-20 (STJLR.03.5006 oil spec) into one product.
Currently Castrol EDGE Professional EC 0W-20 is only available for purchase through Jaguar and Land Rover dealership locations.
​

Castrol EDGE 0W-20 EC (replaces Castrol EDGE 0W-20 E) sold retail in a 1 quart bottle size is also available covering Land Rover STJLR.51.5122 and STJLR.03.5006 oil specifications.

Whats the oil filter spec?

As mentioned in the video, the OEM oil filter is part # LR133455, available from a variety of sources (I found it on eBay and purchased a few.) I am not aware of aftermarket versions of it quite yet, although I am sure they are in the pipeline.

As a JLR newbie (my order is built and shipping soon) is there an "old school" method of gravity draining the oil from an oil pan under the motor rather than using a vacuum system?

Sure, there is still a drain plug down there. You'll have to remove the fairly substantial skid plate to get to it.
