The use of approved DIESEL OIL for the temperature ..... the regular changing of the oil and proper filters..

If you had a way..... the use of a preoiler like commercial engines use is very nice...makes sure your bearings have lubrication from rpm ONE and up.... as much of the wear on an engine happens in the time between start up and getting to working temperature.

I personally change to straight 40 wt oil after 100,000 miles on all my cars.. gas or diesel.... I am in a hot climate to I use a straight number.... those additives which make for multi viscosity ratings take away from the lubrication ability of the oil..... as evidenced by the fact that the worst running conditions.... a small gas air cooled engine... were always specified as needing STRAIGHT 30 wt oil.....
