Are you noticing performance loss or noises?
Sounds like you are maintaining vehicle and not getting codes or performance loss.
As for infrequent driving, oil that only goes 1000km and sits in the pan, for 9-10 months of year is not ideal. A lot of acid and water builds up and is not dissipated without high heat and regular Oil change interval.
This type of neglect can lead to sludge build up and other unwanted by-products of combustion. Even with Synthetic.
Car has to be driven, and/or oil changed more frequently.
Catch cans will alleviate some issues, but irregular operations require different mindset.
No different if you track your car. It requires a different maintenance schedule than a DD.
