Description
- The present invention relates to the field of vehicles. More particularly, the invention relates to a method and apparatus for protecting a vehicle from worn engine oil.
- Engine oil is used for lubricating internal combustion engines. In addition to lubricating moving parts, the engine oil also cleans, inhibits corrosion, improves sealing, and cools the engine by carrying heat away from moving parts.
- Engine oil is essentially classified by the viscosity thereof. The viscosity is a function of the temperature. The main parameter is the viscosity of the oil at the working temperature. The other parameter is the viscosity at the cold temperature, which is when the engine is not at work.
- Oil engine is characterized by the Society of Automotive
- Engineers (SAE) as described by way of the following examples. The viscosity of oil engine characterized by SAE 50 is between 16.3 and 21.9 centiStokes (cSt) at 100 deg. C, which is a typical working temperature. The viscosity of oil engine characterized by SAE 20 is between 5.6 and 9.3 centiStokes at 100 deg. C. Accordingly, the viscosity of oil engine characterized by 20W-50 (W stands for winter grade) is 5.6 centiStokes at cold temperature, and between 16.3 and 21.9 centiStokes at 100 deg. C.
- Engine oil, must be changed from time to time. Vehicle manuals provide schedules to determine how often, estimated by time and distance intervals, to change the oil.
- However, these schedules only estimate when the oil is worn out, and thus the oil is not sufficiently utilized. Also, users often forget to change the oil.
