I have a 2016 Model Beta 30 with the shallow sump. I just changed the oil for winter storage, and when I re-fill I only add about 4 liters of oil before the dipstick indicates full (at the top hole in the stick). This is after I have started the motor to let the filter fill. The manual indicates 5 liters is the capacity. The engine is not at an extreme angle.
I never really checked the capacity before, so I am now wondering if I have not added enough oil?
The oil pressure light is operating as expected (on when in heat position, then off when running)
I don't want to over fill, but also don't want too little oil.
