  "text": "Drain and weigh procedure\n1.\nThe engine shall be filled with new oil. If a constant volume oil sump system (as described in ASTM standard D7156-09) is used, the oil pump shall be turned on while filling the engine. Enough oil charge shall be added to fill up both the engine and external sump.\n2.\nThe engine shall be started and operated over the desired test cycle (see points 2.2.15 and 2.4.4.8.3.1) for a minimum of 1 hour.\n3.\nOnce the cycle is complete, oil temperature shall be allowed to stabilise at a steady-state engine condition before shutting the engine down.\n4.\nA clean, empty oil drain pan shall be weighed.\n5.\nAny clean supplies that are to be used during the oil drain (e.g. rags) shall be weighed.\n6.\nThe oil shall be drained for 10 minutes with the external oil pump (if equipped) powered on followed by an additional ten minutes with the pump powered off. If a constant volume sump system is not used, the oil shall be drained from the engine for a total of 20 minutes.\n7.\nThe drained oil shall be weighed.\n8.\nThe weight determined in accordance with step 7 shall be subtracted from the weight determined in accordance with step 4. The difference corresponds to the total weight of the oil removed from the engine and collected in the drain pan.\n9.\nThe oil shall be carefully returned to the engine.\n10.\nThe empty drain pan shall be weighted.\n11.\nThe weight determined in accordance with step 10 shall be subtracted from the weight determined in accordance with step 4. The result corresponds to the weight of the residual oil in the drain pan that was not returned to the engine.\n12.\nAny dirty supplies which have previously been weighed pursuant to step 5 shall be weighed.\n13.\nThe weight determined in accordance with step 12 shall be subtracted from the weight determined in accordance with step 5. The result corresponds to the weight of the residual oil which remained on the dirty supplies that was not returned to the engine.\n14.\nThe residual oil weights calculated in accordance with steps 11 and 13 shall be subtracted from the total weight of the oil removed, calculated in accordance with step 8. The difference between those weights corresponds to the total weight of the oil returned to the engine.\n15.\nThe engine shall be operated under the desired test cycle(s) (see points 2.2.15 and 2.4.4.8.3.1).\n16.\nSteps 3-8 shall be repeated.\n17.\nThe weight of the oil drained pursuant to step 16 shall be subtracted from the weight obtained in accordance with step 14. The difference between those weights corresponds to the total weight of the oil consumed.\n18.\nThe total weight of the oil consumed calculated pursuant to step 14 shall be divided by the duration, in hours, of the test cycles carried out in accordance with step 15. The result is the lubricant consumption rate.",
