Usage:
This shop standard specification lists unigrade and multigrade lube oils for motorcar transmission units to DIN 51512 and assigns them to API classification GL 4 and/or GL 5. The selection of these lube oils is based, inter alia, on a defined, 'actual' viscosity (ISO viscosity) because the SAE viscosity parameter commonly applied to motorcar transmission units may appear in several ISO viscosity categories (see following diagram). It is to be noted that micro-pitting (frosting) test results are not yet available for these oils so that they must exclusively be used for L+S mobile gears.
NOTE: When selecting a HYP lubricant brand the viscosity specification on the nameplate and/or in the operating manual is to be compared and adapted to the lubricant specified included in the operating manual.
L+S Identification for a motorcar transmission oil of viscosity SAE 80W-90 HYP SAE 80W-90.
