The downstream oil sector includes oil refineries and the selling and distribution of natural gas and products derived from crude oil. Such products include liquefied petroleum gas (LPG), gasoline or petrol, jet fuel, diesel oil, heating oil, lubricants, asphalt and petroleum coke.

LabWare provide analysis for the distribution network for diesel, gasoline and jet fuel in many locations worldwide. Products are delivered to distribution points across regions, where samples are then analysed to check that there has been no contamination during transportation.

The storage facilities at the distribution centres are checked for settling of the products and then the road tankers that are used to ship the products to the filling stations are checked as they are loaded - with tankers being checked randomly as they leave the distribution facility. Testing at the centres is fully automated and includes distillation, flash point, RON, MON and density.
