I get you're referring to 'faff' in terms of ensuring the oil level is on its full mark, however when it comes to checking levels in general I don't find it a faff at all.Do you honestly think that the "Full" mark is so accurate, that your days of faffing (to hit it, spot on) make any material difference?
Lift bonnet, quick visual check of coolant, brake and windscreen washer levels. Pull dipstick, wipe, reinsert, pull, visual check, reinsert.
Assuming all's okay, the check from bonnet up to bonnet down takes around 2 minutes. I get there are sensors etc checking these things when the car's 'on', however I prefer being able to check them and if required refill levels myself between servicing.
Of course the garages (especially main dealers) would be cock-a-hoop if you booked your car in every time you wanted something checked beyond what the dash is telling you.
