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.
