摘要
A process for preparing Fischer-Tropsch derived lubricating base oils by blending a Fischer-Tropsch distillate fraction having a viscosity of 2 or greater but less than 3 cSt at 100 degrees C. with a Fischer-Tropsch derived bottoms fraction; lubricating base oil compositions having a viscosity between about 3 and about 10 cSt at 100 degrees C. and a TGA Noack volatility of less than about 45 weight percent; and finished lubricants using the aforesaid lubricating base oils.
