3. The lubricating oil molecules can be divided into three broad groupings:
 Paraffinic
 Naphthenic.
 Aromatic:

6. •The need to conserve crude reserves.
•Minimizing unemployment through the building of used lube oil recycling plant.
•The elimination environment pollution source of used lubricant.
IMPORTANTS AND BENEFITS OF RE-REFINING
•Reduce dependence on base oil imports saving foreign exchange.
•Prevent ground water contamination and pollution.
•Preserve natural resources such as coal and crude oil.
•Reduce sewage treatment costs.
•Eliminate improper burning of waste oil as fuel, which generate toxic fumes and air pollution.

Pure mineral oil has good lubricating properties , but it is the additives in the oil that gives it
is characteristics and enhances its lubricating properties enable it to meet the modern
requirements . List of additives that are added in lube oil are-

20. •Used oil is pollutant and by re-refining, the pollution is reduced. Hence it
should get a status of eco-friendly technology and get grants and incentives
from the ministry of environment.
•The quality of thoroughly re-refined oil is comparable with nascent base oil.
Hence it should be evaluation awarded import-substitute status.
•While making fresh lubricating oils blending with 5-10% of re-refined base oils
should be done for viscosity correction.
•All such blended oils should be stamped with green lable to make the public
aware about the concept of re-refining.
•The eco-conscious customer would buy the product with green labels.
Since re-refining leads to oil conservation the concept of re-refining should be strongly
supported by the petroleum conservation research association
