Your proof that what you ordered is what arrived. On one invoice, petrol read 727.300 and diesel 820.500 — never the same. The figure is corrected to fifteen degrees before it is printed. Fuel swells in the heat and shrinks in the cold. That is why. When the tanker lands: read the invoice, take your reading, write both. This is about running a pump, not about the app. Made to be forwarded.
