Note 10 . Segment Reporting The Partnership engages in the purchasing, selling and logistics of transporting petroleum and related products, including domestic and Canadian crude oil, gasoline and gasoline blendstocks (such as ethanol and naphtha), distillates (such as home heating oil, diesel and kerosene), residual oil, renewable fuels, natural gas and propane.
