reason in high oil consumption are more like differential pressure after and before oil separator is much,oil separator collapsed,syphon tube inside oil separator is chocked or broken.

reason for oil thickening is accumulation of moisture in oil much,wrong selection of comressor oil,continouse running of boiler under high element temperature.

reason for burnt smell is caused due to exceed of running hours of compressor oil and you fail to replace with fresh oil before.
