Fuel consumption (Audi 80 B3)

Oil consumption in internal combustion engines means oil consumption as a result of its combustion and in no case its leakage from the oil bath, cylinder head, etc. due to depressurization.

Normal oil consumption occurs in small quantities in the cylinders; when removing combustion and friction products. In addition, the oil wears out under the influence of high temperatures and pressures to which it is subjected during engine operation.

Among other things, consumption is affected by operating conditions, driving style, and manufacturing tolerances of parts. The maximum oil consumption should be 1.5 liters per 1000 km.

Oil must be added when the level reaches the "Nachfule" (Top Up) mark.
