Study Notes

Function and Importance of Lubricating Oil

Lubricating oil forms a separating film between moving parts, minimizing direct contact and friction.
Reduces frictional heat and wear, protecting engine components.
Transfers heat through conduction, utilizing airflow from the oil pan and oil cooler.
In recirculating oil pumps, the positive crankcase ventilation (PCV) system aids in heat transfer.
Modern recirculating pumps are standard in passenger cars; total-loss oiling is more common in small engines.
Motor oil cleans the engine by removing sludge and varnish using dispersants and detergents.
Neutralizes acids from fuel and oxidation, improves piston ring sealing, and aids in engine cooling.

Managing Used Oil

One oil change can contaminate one million gallons of fresh water, impacting 50 people's supply.
Used motor oil is insoluble, persistent, toxic, and slow to degrade, posing significant environmental risks.
Care should be taken to avoid spills when collecting used oil; use leak-proof containers.
About four million individuals recycle or reuse motor oil each year, highlighting community engagement.
Used oil filters should be properly drained and recycled at designated centers.

Benefits of Recycling Used Oil

Recycling prevents soil and water pollution, reducing environmental impact.
Used motor oil can be re-refined into new oil or converted into fuel oils, serving as a resource for the petroleum industry.
Used oil is efficient for energy production; it burns better with lower carbon emissions.
Recycling processes require less energy compared to crude oil extraction.
Encourages less environmental strain by decreasing the demand for crude oil extraction.

Pro’s of Reusing and Recycling Oil

Used oil can serve alternative purposes, such as lubricants for household items and equipment.
Reduces landfill waste and the need for extensive waste management resources.
Offers cost savings by providing a cheaper and effective energy source.
Minimizes the use of harmful chemicals needed for cleanup operations.

Community Education and Disposal Programs

Los Angeles promotes proper used oil disposal through educational and ordinance programs targeting DIY oil changers.
Public outreach includes mass media campaigns, school programs, and community engagement to raise awareness.
Key elements for effective used oil collection include providing free collection containers and making disposal convenient.
Strong penalties for improper disposal aim to deter illegal dumping and encourage recycling.

Strategies for Effective Oil Disposal

Retail clerks should inform customers about proper disposal and provide free collection containers at the point of sale.
Suggest curbside collection options alongside retail drop-off for used oil.
Implement fines for illegal dumping, with a system for public reporting to enhance accountability.
Conduct pilot studies to evaluate the efficacy of different disposal strategies on community participation and compliance.
