Although the Jaguar service schedule states 64,000 miles or 48 months (whichever comes first), I will be having the rear diff oil changed every 25,000 miles or 48 months (whichever comes first) instead.
At the moment, I’m only doing around 6,000 miles per year so it doesn’t make much difference to me.
The reason for renewing the diff oil more frequently is to help ensure the diff doesn’t break down, as this forum suggests that many F-Types suffer with differential failures due to oil contamination etc.
Try using the link below to see if your Jaguar service schedule includes the diff oil change.
Input your vehicle identification number (VIN), click on 'servicing information' then 'service type' dropdown arrow and select 64,000 miles / 48 months service.
