The engines of modern automobiles are constantly being improved. In recent years, automakers have focused on improving fuel economy by developing high-efficiency engines, often using turbochargers and gasoline direct injection. To provide proper lubrication for these engines with tighter tolerances and higher operating temperatures, lubricant manufacturers have developed advanced engine oils.
However, in modern economical and technologically advanced internal combustion engines, the problem of low-speed premature ignition (LSPI) arises.
Low-speed pre-ignition (LSPI) is the effect of auto-ignition of a fuel mixture during compression at low speeds and loads. This phenomenon occurs not only in turbocharged engines, but also zamIt is also inherent in modern turbocharged engines with direct injection (GDI) engines.
Studies on the effects of oil on LSPI formation have shown that engine oil composition can have a positive effect on the effectiveness of LSPI.
General Motors pioneered a solution to avoid LSPi by reengineering Dexos 1 as Dexos 1™™ Gen 2.
In 2020, an updated version of the API SP standard was published and the new standards of the International Lubricant Standardization and Certification Council, ILSAC GF-6A and ILSAC GF-6B, came into force.
The new oil formulation changed the proportions of detergent additives and selected the right combination of base oils to achieve the optimal balance of the use of additives containing zinc, phosphorus and molybdenum.
Other positive features of API SP and ILSAC GF-6A oils are, zamthe reduction of wear in the transmission chain, the reduction of friction losses and the reduction of fuel consumption.
