ABSTRACT

The evaluation of friction and wear characteristic in lubrication is investigated by

formulating a bio lubricant. The formulated bio lubricant is needed to acts as an alternative to

reduce the usage of mineral oil that facing a depletion problem and also have a potential to

bring harm to the human and environment. Cooking palm oil that act as a new source is used

to reduce the dependence on mineral oil that commonly used in conventional lubricant. A

portion of 10% to 40% of cooking palm oil ratio is blended with the base SAE 40 lubricant to

produce a bio-lubricant and its properties data recorded. Four-ball tribo testing machine is

used to conduct the friction and wear experiment to examine the formulated lubricants.

Cooking palm oil also can represent as lubricant additive due to its ability to reduce friction

very well. The addition of 30% cooking palm oil into the conventional lubricant shows the

best result in every aspect.
