Hi,
Many years ago I had an interesting discussion with an oil man who advised oil takes in water so even low mileage oil should really be changed. Filter should be ok but drain out old oil.
I do my own servicing and, irrespective of mileage, cover everything in an annual service plus interim inspections.
Some points to consider.....
Did KH change the brake and clutch fluid? If unsure then change it.
Anti freeze.....test
Spark plugs......untighten then retighten (to correct torque) just to ensure a lack of removal doesn’t get them stuck tight.
Hope this helps.
