What is the question?
So technically the oil and filter are about 18 months old approximately, but the car has likely less than 1000km on it in that time (625 miles) on the oil. It is still golden colored and looks almost new. Would you change the oil now or as the car will likely do the same or maybe slightly more km's this summer leave it in and run it for the summer and do a change before putting it away before winter?
In the time I have owned this car it has managed about 12,000 miles and had annual oil changes with a filter every year since 2012.
Now this is not because I am a cheapskate 50% Scot by birth
