Question

Parafins crudes generally give a lower yield of lubricating oils than naphthenic crudes.

(a) True

(b) False

I got this question at a job interview.

Question is taken from Types of Lubricants topic in section Engine Friction and Lubrication of IC Engine

Answer 1

The correct answer is:

(a) True

Paraffin-based crudes generally yield a lower quantity of lubricating oils compared to naphthenic crudes. Naphthenic crudes are often preferred for producing lubricants because they have a higher proportion of base oils that are more suitable for lubricant production, especially in terms of low-temperature performance and stability. In contrast, paraffin-based crudes typically result in oils with higher pour points and less desirable characteristics for lubrication.
