Valvoline Inc. says it has developed a new motor oil formulation that helps protect gasoline engines from low-speed pre-ignition (LSPI) issues that can affect turbocharged and gasoline-direct-injection engines.
The blend will be used in all Valvoline motor oils for gasoline engines in North America. Valvoline says the formulation is the first to meet proposed standards approved by the American Petroleum Institute.
LSPI is an abnormal combustion event caused by the higher in-cylinder pressures common in engines with turbocharged and/or gasoline direct-injection engines during low-speed, high-torque operations. In addition to engine noise and rough idling, LSPI can cause catastrophic damage that results in engine failure, Valvoline says.
The supplier claims its new formulations also can protect against excessive timing-chain wear and other potential problems.
