Like tax, servicing does not have to be taxing.
Don a pair of disposable gloves and equip the garage with some simple tools and to lie on the floor, is all it takes.
By this means I am able to service the 4/4 more frequently and know the job is done to my satisfaction.
Magnetic drain plugs assist in keeping the engine and gearbox oil cleaner for longer, but I will change it well before it gets to the dirty black stage..
The first service was paid for by the first owner, not me by the way.
