I bought this for a small electric 4-cycle Honda generator for emergency electrical backup.  Because the generator is something that I use VERY infrequently it is essential that I remove the fluids (oil/gas) with each use.  I needed something small(for convenience of space) and reliable, as I don't want flammable liquids falling in the wrong place on an electric generator.  (Bad combination).  I also use this for my 4-cycle 150cc scooter for regular oil changes.
