Upon Release of CK-4 API Licensing (Dec/2016) FORD issued a statement stating ″Ford testing has shown some CK-4 type formulations have shown inadequate wear protection compared to CJ-4 formulations developed and licensed before 2016″ [6] Similarly, Stellantis also issued a TSB citing Oil requirements that eliminated CK-4 Rotella from being ...
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 ...
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 °C.

It stipulates the lubricating oil requirements for 2-stroke gasoline engines, such as those used in motorcycles, general-purpose machines, and outboard motors, [1] and was established in 1994. [2] For 2-stroke oil, lubricity, cleanliness, exhaust smoke, and exhaust system blockage are evaluated using the test methods specified in JASO M 340, M ...
The company is currently run by the Barkett family. The Barketts entered the motor oil business by buying Petroleum Packers, a company in Port Tampa Bay, in 1977. In 1997 the Barketts acquired Amalie Oil from Sun Oil Company and merged Petroleum Packers into Amalie. [3] The combined company has been headquartered in Tampa, Florida, since 1998. [5]
The oil is dyed blue to make it easier to recognize in the gasoline. It appears black in this bottle because it is not diluted. Two-stroke oil (also referred to as two-cycle oil, 2-cycle oil, 2T oil, or 2-stroke oil) is a special type of motor oil intended for use in crankcase compression two-stroke engines, typical of small gasoline-powered ...
