A. Shell Corena S2 P 100 is for reciprocating (piston) air compressors in higher-duty service where ISO VG 100 mineral compressor oil is specified.
A. Shell Corena S2 P 100 is ISO VG 100 — the heavier mineral compressor oil viscosity for higher-duty reciprocating compressor service.
A. Shell Corena S2 P 100 meets ISO 6743-3 (compressor oil classification); DIN 51506 (industrial compressor oil specification); and DIN 51575.
A. All three are Shell Corena S2 P mineral reciprocating compressor oils. They differ only in viscosity grade: S2 P 68 is ISO VG 68 for standard service; S2 P 100 (this product) is ISO VG 100 for higher-duty service; S2 P 150 is ISO VG 150 for high-duty service with elevated discharge temperatures.
A. No — Shell Corena S2 P is specifically positioned for reciprocating (piston) compressors. Rotary screw compressors require Corena R variants (such as Corena S3 R or S4 R) with formulation suited to continuous-rotation duty.
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.
