Phosphorus is a key anti-wear component in motor oil and is usually found in motor oil in the form of zinc dithiophosphate (ZDDP). Each new API category has placed successively lower phosphorus and zinc limits, and thus has created a controversial issue of obsolescent oils needed for older engines, especially engines with sliding (flat/cleave ...
Several owners of high performance model cars have adopted its use due to its high heat tolerance and its resistance to shearing. Rotella T6 is a Non Energy Conserving Oil, and does not meet GF-5 Oil specifications. When Rotella T6 was revised for the API specification (for use in spark ignition engines), its zinc levels were effectively reduced.
The grades with a W designation are considered Winter-grades, and denote an engine oil's low-temperature properties, while non-winter grades denote an engine oil's properties at the operating temperature of an engine. [5] The SAE 8 through SAE 16 viscosity grades describe oils that can improve fuel economy through reduced hydrodynamic friction ...
zinc dialkyl dithio phosphate (ZDDP), probably the most widely used [2] in formulated engine oils, also acts as a corrosion inhibitor and antioxidant; Tricresyl phosphate (TCP), used for high-temperature operation, often used as an AW and EP additive in turbine engine lubricants, and also in some crankcase oils and hydraulic fluids
Oil-soluble organophosphates, with or without zinc, have excellent high-pressure and antiwear properties, and provide corrosion protection especially in presence of chlorinated hydrocarbons. Zinc dialkyldithiophosphates (ZDDP) start decomposing at 130-170 °C, while the activation temperature of tricresyl phosphate (TCP) typically exceeds 200 ...
Although PTFE has been called "the slickest substance known to man", [15] [16] it would hardly do any good if it remains in the oil filter. Some mass-market engine oil additives, notably the ones containing PTFE/Teflon (e.g. Slick 50) [17] and chlorinated paraffins (e.g. Dura Lube), [18] caused a major backlash by consumers; the U.S. Federal ...
