Castrol Alpha SP 100 is a mineral-oil-based industrial extreme-pressure (EP) gear lubricant in the Castrol Alpha SP range. The product is formulated for enclosed industrial gear units, providing wear protection, oxidation stability, and protection against corrosion and micropitting.
The ISO VG 100 viscosity grade is positioned for lighter-duty general-purpose industrial gearboxes — typical applications include small to medium enclosed gear units running at moderate speeds.
Approvals and performance levels are positioned within the DIN 51517 Part 3 (CLP) industrial EP gear oil specification.
Castrol Alpha SP 100 is also available in a 208-litre drum (PRD00001355) for workshop bulk supply.
The 20-litre pack format is suited to single-machine top-up and small workshop service. Store sealed in the original packaging, in a clean, dry area away from extremes of temperature, to preserve product performance over its shelf life.
Refer to the manufacturer technical datasheet for the full performance specification and approved service intervals.
The Castrol Alpha™ SP gear oil range of high quality lubricants are based upon highly refined mineral oil, enhanced with an extreme pressure additive technology providing good thermal stability and high load carrying capacity. The extreme pressure additive system not only provides high load carrying capacity, but was designed to provide microscopic wear protection. Microscopic wear protection, also known as micropitting protection, is critical in preventing destructive wear at the micro level therefore extending gear life and meeting the evolving demands of smaller and higher output gear boxes. Application The Alpha SP range is recommended for the lubrication of industrial gear boxes using forced circulation or splash and oil bath lubrication. They may be used for the lubrication of spur and helical gears and in some lightly loaded worm type gear applications. They have very good viscosity characteristics to ensure starting torques are not excessively high in cold operating conditions. The additives are compatible with the ferrous and non-ferrous metals used in industrial gear units. The Alpha SP range is compatible with the most common types of seal materials.

A. Castrol Alpha SP 100 is for enclosed industrial gear units in lighter-duty general-purpose service — typically small to medium gearboxes running at moderate speeds where ISO VG 100 industrial EP gear oil is specified.
A. Castrol Alpha SP 100 is ISO VG 100 — a lighter industrial gear oil viscosity for lighter-duty general-purpose service.
A. Castrol Alpha SP 100 is positioned within the DIN 51517 Part 3 (CLP) industrial EP gear oil specification.
A. Both are Castrol Alpha SP industrial EP gear oils in the same range and meeting DIN 51517 Part 3 (CLP). They differ only in viscosity grade: Alpha SP 100 (this product) is ISO VG 100 for lighter-duty general service; Alpha SP 150 is ISO VG 150 for slightly heavier-duty service.
A. Castrol - Alpha SP 100 Gear Oil - 20 Litre is a mineral oil — formulated with conventional petroleum base stocks for standard drain intervals and service in equipment specifying mineral-grade lubricants.
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. 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.
