Starburst Symbol
Definition:
Oils that display the starburst symbol must meet the requirements of ILSAC GF-2 to display the mark. The requirements are:
- Oil must meet requirements for low-temperature pumping/cranking (essentially oil must be a l0W or lower W grade), gelation index (a measurement of the low-temperature gelation tendency of the oil), and contain a maximum level of phosphorus (to ensure catalyst durability);
- Oil must pass the fuel economy requirements of the Sequence VIA test. Passing this test also allows for energy conserving to be displayed within the API Donut symbol;
- Must pass engine test performance (deposit and wear control, rust control, shear stability, corrosion protection, oxidation control) as well as requirements for volatility, foaming tendency, homogeneity miscibility, high-temperature deposits and filterability.
