               Regular oil changes are essential for maintaining motor vehicle engine performance and longevity. The regular changes of oil/fluid are considered as the preventive maintenance service of the vehicle specifically the oil/fluid of engine, manual transmission, automatic transmission and differential. 
             However, traditional methods for oil and fluid removal involve manually draining used oil through the engine’s, transmission’s, and differential’s drain plug, a process that is often labor-intensive, time-consuming, and prone to environmental contamination due to oil spillage (Boyd, Lee, & Patel, 2018).

           In common, the traditional oil/fluid change procedure poses several hazards: lifting the entire vehicle, crawling or working underneath it, splashes of hot or dirty oil onto the body or floor, bumping one's head on vehicle parts, the risk of damaging the oil pan threads from frequent loosening and tightening, and environmental risks from improper disposal of used oil. These issues endanger students and technicians and raise concerns about safety, hygiene, and ecological impact (Fernandez, 2025).

           Also, the improper disposal of used motor oil/fluid during the removal and refilling of oil/fluid presents a significant environmental hazard. The U.S. Environmental Protection Agency (EPA) highlights that a single gallon of used motor oil can contaminate up to one million gallons of fresh water, emphasizing the urgent need for improved oil/fluid change methods that reduce environmental risks (EPA, 2021). Furthermore, current oil/fluid change practices frequently involve specialized tools or adapters that lack universal compatibility, limiting their use across different vehicle models and increasing maintenance complexity and costs (Smith & Jones, 2019).
          Shortcomings of the existing process of removing and refilling oil/fluid of vehicles, led the researcher to conceptualize a simplified and safer method for performing standard oil changes—both environmentally friendly and user-centric. The goal is to innovate a process that reduces physical risks while enhancing efficiency and sustainability in automotive servicing. This study will introduce a semi-automated oil-changing machine powered by a 12V battery sustained by solar energy. This innovation merges electrical and mechanical systems to efficiently and safely drain and refill engine oil, transmission fluid and differential fluid, which will surely present a significant improvement over traditional oil/fluid-changing practices. The machine will feature a compact, user-friendly, and cost-effective design. It will offer dual functionality, allowing it to extract used oil/fluid and refill/replenish fresh oil/fluid without lifting the vehicle or going underneath the vehicle just to remove the oil/fluid drain plug. This makes the process safer, environmentally friendly, and more inclusive, as it can be easily operated by any driver or technician, regardless of gender or physical strength. Most importantly, the machine reduces the time needed for an oil change, offering technicians and car owners convenience and help in the preservation of the mother earth.

The study has possible various output base on 6Ps such as:
