CHAPTER ONE
1.0 INTRODUCTION
1.1 Preamble
From time immemorial, liquids, including water, have been used as lubricants to reduce
friction and wear and remove heat between two surfaces in contact. At present, lubricating oil also called lube oil is the most commonly used lubricant because it has found a wide range of application in the field of engineering.
A lubricant, sometimes called lube, is a substance (often a liquid) which is introduced between two surfaces in contact moving relative to each order to keep them separate under all loads, temperatures and speed thus minimizing friction and wear. The substance may act as cooling fluid removing heat from the system and also protect surfaces from the attack of aggressive products formed during the operation. Lubricants may also perform the function of dissolving and transporting foreign particles (http://www.Weareoil

Majorly, there are solid and liquid lubricants. Air and other gas based lubricants are there, but for the purpose of this research work, consideration is limited to liquid lubricants. Examples of liquid lubricants are: mineral oils, vegetable oils and synthetic oils.
The most common liquid lubricants are the mineral oils. This is because of the supply of crude oil. The term mineral oil is used here to mean lubricating base oil derived from crude oil that is refined from naturally occurring petroleum. Since they are commonly used, important information about their properties is now available.

ABSRACT - [ Total Page(s): 1 ]The performance of the oils selected in this work was tested for considering Viscosity, Viscosity Index, Density, Flash Point, Pour Point, and Carbon Residue. The most important of all the properties which makes the oil protect against wear is viscosity that helps to reduce friction between moving parts in the engine. The Viscosities of the oils; Oando SAE 20W50, Total SAE 20W50, Mobil 1 SAE 0W40, Total SAE 40, and AZ SAE 20W50 at 24.8°C (room temperature) and 100°C (maximum test temperatu ... Continue reading---
