A. HyperDrive KX+ 80W-90 GL-5 is for hypoid final-drive gears — spiral-bevel axles, steering gearboxes and other applications where API GL-5 and MIL-L-2105D performance is required.
A. API and ACEA are the universal lubricant performance standards every reputable oil meets. They are your baseline check — match the code your handbook specifies (e.g., API CI-4 or ACEA E7 for heavy-duty diesel) and the oil is technically suitable for your machine. Every oil on our site lists its API and ACEA classifications.
A. HyperDrive KX+ 80W-90 GL-5 meets API GL-5; and MIL-L-2105D.
A. An OEM Specification is the lubricant requirement set by a vehicle or equipment manufacturer (e.g., MB 228.3, VW 504.00). When an oil lists the code, the oil manufacturer has developed and tested it to meet the criteria the equipment manufacturer requires. Match the code in your handbook and you have a lubricant engineered for your machine.
A. An OEM Approval means the oil has been formally tested and signed off by the equipment manufacturer and listed on their official approved-products register (e.g., MB-Approval 228.3). An Approval confirms the oil is recognised by the equipment manufacturer for service use in their machines.
A. HyperDrive KX+ 80W-90 GL-5 carries MAN M341; and David Brown ET1 industrial spiral-bevel gearbox specification.
A. MIL-L-2105D is a US military specification for automotive hypoid axle gear oils — historically the reference specification that API GL-5 is based on. Some equipment specifications still reference MIL-L-2105D directly.
A. Both are HyperDrive API GL-5 hypoid axle oils. KX+ 80W-90 (this product) is the mineral SAE 80W-90 multigrade for general-service automotive axles. KXR 75W-90 is the fully synthetic SAE 75W-90 multigrade for highly stressed powertrains and improved cold-start performance.
