Premium Motor Spirit truck-out volume, monthly

Monthly truck-out volume of Premium Motor Spirit (PMS, petrol/gasoline) in Nigeria, January 2018 to December 2022, in litres. Source: NBS Annual Abstract of Statistics 2023, Table 244; data provider Nigerian Midstream and Downstream Petroleum Regulatory Authority. Truck-out volume is product loaded out of depots into road tankers — a downstream DISTRIBUTION measure, not production, imports or consumption. ⚠ PRISM HAS ADDED THE WORDS "PREMIUM MOTOR SPIRIT"; THE SOURCE CAPTION NAMES NO PRODUCT. Table 244 is printed as "Monthly Distribution of Truck-Out Volume, 2018-2022" with no product named anywhere on the page, which invites reading it as all petroleum products. It is PMS only. Proof, three independent checks: (1) Table 244's 2019 annual TOTAL is 20,584,964,536 litres and Table 243's PREMIUM MOTOR SPIRIT column total for 2019 is 20,584,964,536 litres — identical to the digit, eleven significant figures; (2) Table 243's six zonal PMS volumes (3,679,186,315 + 1,400,981,849 + 3,657,426,578 + 2,304,126,397 + 3,294,944,574 + 6,248,298,823) sum to exactly 20,584,964,536, so that column is internally sound and is genuinely the PMS figure; (3) the all-product 2019 truck-out total from Table 243 is 27,146,843,990 litres (PMS 20,584,964,536 + AGO 5,158,861,275 + HHK 270,215,589 + ATK 1,048,271,112 + LPFO 84,531,478), which Table 244 does NOT report. Serving this table under its printed caption would understate Nigeria's total product truck-out by 24.2%. The printed caption is preserved verbatim in the dataset's data_provider_note. Table 244's twelve monthly values sum to its own printed annual TOTAL exactly in all five years. Period follows Prism's monthly convention: period = YYYY-MM with `year` and `month` populated. The printed annual TOTAL row is not a member of this series; it is served as nbs-mfg-pms-truck-out-volume-nga. 60 monthly points — the only genuine time series in this chapter.
