Kinematic viscosity of single walled carbon nanotubes (SWCNTs)/ lube oil cuts nanofluids containing 0.01-0.2 wt% single walled carbon nanotube (SWCNTs) was investigated at 25°C-100°C. The nanotube diameter was ~ 2nm and lengths ranging from 10 to 15μm. Kinematic viscosity of nanofluids increases with increasing particle weight fraction and decreasing temperature. The viscosity index of oil-based SWCNT nanofluids is increased up to 32.94% at a weight fraction of 0.2%.
