For purposes of Oil Analysis Program (OAP) trend analysis, replacement, replenishment or drain and flush of lubricating fluids in excess of half an engine’s oil capacity (2.5 gallons or more) will be considered an Oil Change and the engine will be placed in code Charlie (C) for three flights to establish a new working trend.
SP specifies more stringent engine oil performance requirements for spark-ignited internal combustion engines. These include a chain wear test and a test for very low-viscosity engine oils. The standards also include a test designed to protect against a phenomenon experienced by some gasoline engines known as Low-Speed Pre-Ignition (LSPI). [12 ...
OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.
Moments before the deadly crash of a charter jet on a Florida highway, three warnings about oil pressure problems in its two engines sounded, the National Transportation Safety Board said in a ...
Spectrometric Oil Analysis Program (SOAP) is a method used by aircraft operators, including several Air Forces of the World, to test the health of aircraft engines by performing frequent laboratory testing of the engine oil. The tests reveal the chemical composition of any metal particles suspended in the oil samples. By comparing the results ...
Ferrography is a method of oil analysis used to inspect the severity and mechanisms of wear in machinery. This is achieved by separating ferrous debris from lubricating oil by use of a magnetic field with an instrument called a ferrograph, the result is then examined with microscopy. A trained analyst can then diagnose faults or predict failures.
Motor oil, engine oil, or engine lubricant is any one of various substances used for the lubrication of internal combustion engines. They typically consist of base oils enhanced with various additives, particularly antiwear additives , detergents, dispersants , and, for multi-grade oils, viscosity index improvers .
A plan to look and drill for oil in the Apalachicola River basin has drawn angry protests from Leon County’s delegation to the Florida Legislature and a pledge to seek stronger protection for ...
