Anyone know what is the friction coefficient of oil/lubricant?
or anyone know where to search for the information?
i had been searching through everywhere but cant get the correct exact value of the coefficient
Thanks=)

It depends on the materials the lubricant is between as well as the specific lubricant istelf. You aren't going to find a exact value that represents all lubricants. THe best you are going to do with the information you provided is rough guidelines.

Thanks dknguyen, i guess i found my answer inside the webpage
thanks a lot =)

Get thee a copy of the "CRC Handbook of Chemistry and Physics". Libraries usually have a copy.
If you want to measure it yourself all you need is an adjustable inclined plane. Draw yourself a balance of forces diagram so you can see the normal force and the friction force and gravity. Now incline the plane slowly until the block starts to slide. From the balance for forces and the angle of the plane, you should be able to calculate the friction force which will give the coefficient of friction if you know the normal force.
