Abstract
The viscosities of groundnut oil samples in Katsina-Ala metropolis were obtained and measured using the Ostwald Viscometer. The viscometer was calibrated prior to using 40% sucrose solution and the cell constant of 6.0222 x 10-6 pakg-1-m3was obtained. This value was used to evaluate the viscosities of eleven oil samples which include; KCMGOS A, KCMGOS B, KCMGOS C, KCMGOS D, KCMGOS E, PGOSHQ, PGOSAI, PGOSCW, PGOSM, PGOSI, and SEGOS. The selection was done using hat and draw method to avoid being biased in selecting samples. The results showed that at low temperatures the viscosities of the oil samples were high. However, there was a rapid decrease in the viscosity value as temperature increased gradually from 298k to 313k. There was consistency in the viscosity values of the oil samples exception of an oil .L. sample with high deviation in the viscosity value (KCMGOS-D). This high deviation occurred because the oil was adulterated or contaminated.
