Have only done this once myself Paul,
Not really for the Nano IMHO unless someone brings ramps, axle stands, or Trolley jacks, Oil Spill Granules and a T4 to monitor temperature for fluid change,
but if you have the correct bits and someone likes lying on their back for a while........perfect.
There are of course differences of opinion in way to drain, when, and if T4 should be used, but above just following the MGR method.
