Every blending company like Caltex, Total, Shell, ZIC, etc. sale their products through main dealers/investors who buy fluids in thousands of liters from them.
Example. The company PEL, Dawlence, Haier, etc. don’t have their direct sales centers. But there are investors who buy their products from them in thousands and supply to their distribution centers.
Here in Lahore, we have all those main dealers sitting in Badami Bagh like Pakistan Oil Store, Kasur Oil Store, Butt Brothers, etc. You can walk in there and can buy any lube with eye close because they sell 101% authentic products. So there must be similar distributors in Karachi too sitting somewhere in main auto markets. I am surprised that why no one has idea about them in Karachi.
