oil change intervall - never ending story
the mileage between two changes depends on
- the way one uses a haya
and
- the maintenance sheet in the manual.
if one uses the haya only for short runs to the bakery and back home even 2500 miles can be to much
if the haya gets really warm, means oil temp at 90°C and hogher, the intervall can be enlarged up to 5500 miles.
the best way to control the temp is to install a temp-gauge eg from "koso" in combi with a m14x1.5 feeler in the oil-galery left side, in the hight of middle of the oil hose.
plugbolt (#38 in the fiche below) out and feeler + new seal in + 17 Nm.

the type of the oil has to follow the prescription in the manual
very 1st change after 600 mi from mineralic to half / full synthetic oil is a need
and lateron the half / full synthetic oil is prescribed.
the oil must imperatively be pruduced for oil-bath-clutches (all other oils cause clutch sliding)
the name of the manufacturer (more or less) never matters.
