The remote greasing kit mentioned by Robbie is good and as said above, is very useful when on a touring holiday.
Before I fitted the kit (it is quite easy to fit), we did a trip to the South of France meaning I had to get the greasing done halfway through the trip. Took the Mog to a village Renault garage and they did the greasing and I think they charged 8 euro. They were very interested in the car and spent some time looking over it and asking questions.
