Talking specifically about such non-exotic vehicles as long distance semi-trucks, city buses etc., what is the today's de-facto standard with regard to availability of Automatic Lubrication Systems on such vehicles? Do they usually come equipped with ALS from the factory as standard equipment? Or is it optional equipment? Or, maybe, it is usually installed as aftermarket equipment?
Also, is the support/acceptance of ALS different in different parts of the world, like, say, between US and European truck manufacturers?
