Hi,
I'm in a similar boat to you, car is now 3 years old and only 17k.
I have an oil service regardless every 12months but it will be 2 years on 9th August since my TLC first oil change so I'm now expecting (after reading your posts) I should be asking my dealership to perform the Inspection 1 at this point.
If it was the case that the TLC is purely mileage dependent I'd quite possibly not get my Inspection 1 or 2nd Oil Change
Cheers, Geoff.
