F.3 Engine oil specification
Engine oil classification
Operating range:
The operating range of an engine oil is determined by SAE class. "SAE" is for the union of American engineers
(Society of Automotives Engineers). The SAE class of an engine oil only informs over the viscosity of the oil (lar-
ger number = more viscous, lower number = more highly liquidly) e.g. to 0W, 10W, 15W, 20, 30, 40. The first num-
ber shows the liquid of cold weather, the second number refers to the fluidity with heat. Complete yearly oils have
usually SAE 10W-40, SAE 15W-40 etc.
Quality of oil:
The quality of an engine oil is specified by the API standard ("American Petroleum Institutes"). The API designa-
tion is to be found on each engine oil bundle. The first letter is always a C.
API C for diesel engines
The second letter is for the quality of the oil. The more highly the letter in the alphabet, the better the C für Diesel-
motoren.
Examples for diesel engine oil:
API CG Engine oil for highest demands, turbo-tested
Engine oil types
above 25°C SAE30 or SAE10W-30, SAE10W-40
0°C to 25°C SAE20 or SAE10W-30, SAE10W-40
below 0°C SAE10W or SAE10W-30, SAE10W-40
