Organic Chemistry Petroleum Fractions

  1. Jun 27, 2011 #1
    1. The problem statement, all variables and given/known data
    Why is petrol suitable to be used as a fuel whereas lubricating oil is more suited to lubricate machine joints?

    2. Relevant equations

    3. The attempt at a solution
    Petrol has a low boiling point. It combusts more easily to provide energy to the car. However, lubricating oil does not combust easily due to its high boiling point and would remain in its liquid state to serve its purpose of lubricating.

    I jus began organic chemistry today and i am wondering if my following answer is correct. Do guide me along

    It isn't a question of combustion but of lubrication. How might viscosity affect lubricity?
