had a woman come into work once witha little tap, checked her oil, none on the stick. asked when she had last had a service. she answers
Her- 'what do you mean, its a new car!'.
Me- 'well, its not anymore, its 4 years old. they still need servicing'
Her- 'Really?'...'oh'

Honda civic, 57k on the clock. Original oil from new. amazingly, still going!
