Replacing the engine oil, engine oil filter and gearbox oil. The engine oil service was according to schedule, however according to the Haynes manual gearbox oil it is not needed to be replaced. Since I am taking of the IRD (see other post) I might as well put new oil in it. Getting the oil out is easy, but geting new oil in is a little trickier.
To fill up the gearbox I used a (clean!) garden hose and stuck it in the filler hole.
