A lubricating oil comprising a base oil of specified carbon types, less than 5 wt % hydrocarbon solvent, and a detergent/dispersant additive package, wherein the lubricating oil has a blend kinematic viscosity at 100° C. of 6.5 mm2/s or greater, good low temperature fluidity, and a high exhaust smoke index. Also, similar lubricating oils made using a base oil made from a waxy feed, or comprising a base oil with a low Noack volatility and a pour point reducing blend component, or a base oil with a high viscosity index. Additionally, lubricating base oils meeting the requirements for two-cycle gasoline engine lubricants.
