Beschreibung
Zusammenfassung:	A multigrade engine oil comprising:a) a first base oil, comprising: at least about 55 wt % of the molecules have paraffinic functionality, at least about 25 wt % of the molecules have cycloparaffinic functionality, a ratio of weight percent molecules with paraffinic functionality to weight percent of molecules with cycloparaffinic functionality of about 2, a boiling range between about 359 to 490° C, a VI between about 96 to 106, a flash point between about 190 to 228° C, a kinematic viscosity between about 3.0 to 7.0 cSt at 100° C, and a kinematic viscosity between about 24 to 34 cSt at 40° C; b) a second base oil; and c) an additive package, and wherein, the multigrade engine oil comprises between about 30 to 50 wt % of the first base oil and about 10 to 30 wt % of the second base oil.
