About the Book

'The correct lubricant' is suitable for plant and fleet personnel at all levels, from artisans to engineers and managers, as well as for oil industry representatives and field engineers.

The book covers basic practical information about lubrication and lubricants.

Viscosity, the most important lubricant characteristic in both oils and greases, is covered first, together with viscosity index. Then some other important characteristics, followed by base oils including some synthetics, and finally the critical performance requirements for various applications.

The second part of the workshop deals with applications, starting with engine oils, then automotive gear and transmission oils, greases, industrial gear oils, circulating oils, compressor oils, hydraulic fluids, fire-resistant fluids, machine tool oils, oil cleanliness, storage and storage stability, finally briefly rust preventives and cutting fluids.

In addition to the essential requirements in each application, this part focuses on the difficult question: When is it advisable, or even necessary, to use synthetic lubricants?

The last part is included for people who use the book as a textbook.  They will be challenged to find the correct lubricants to solve various practical problems. If they manage to complete this task, they will show that they have learned a great deal about lubricants.

To help the learners remember important aspects of each chapter, there are many questions and also three revisions in the text. The answers are at the end of the book and on our web page.
