DeLaval Oil Can

This DeLaval oil must be very special.  The can claims that the oil is “produced from the most carefully selected and refined oil stocks which are further subjected to the special DeLaval refining process of centrifugal clarification and filtration”.   It claims to remove oil, grit and wax,  “the elimination of which is possible in no other way”.   It sounds like a great product to have around the farm!
