Castrol Aircol CM 68 is a high-quality mineral-oil-based air compressor lubricant in the Castrol Aircol CM range. The product is formulated for reciprocating air compressors, providing wear protection, oxidation stability and deposit control at compressor operating temperatures.
The ISO VG 68 viscosity grade is positioned for higher-temperature reciprocating air compressor service — typical applications include industrial reciprocating compressors operating at elevated discharge temperatures where ISO VG 68 mineral compressor oil is specified.
Approvals and performance levels include ISO 6743-3 (compressor oil classification); and DIN 51506 (industrial compressor oil specification). The product is tested to ASTM D4052 (density); ASTM D445 (kinematic viscosity); ASTM D2270 (viscosity index); ASTM D892 (foaming); ASTM D1401 (water separability); ASTM D665 (rust prevention); and ASTM D2272 (RPVOT oxidation stability).
Castrol Aircol CM 68 is also available in a 208-litre drum (PRD00002592) 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.
The Castrol Aircol™ CM Air compressor oil range, of high quality lubricants, is based upon highly refined mineral oil, enhanced with additive technology providing excellent thermal and oxidative stability and good load carrying capacity, compared to other products in the same class. Application Aircol CM grades are formulated without zinc additives (ashless oils), recommended for the lubrication of reciprocating and rotary screw air compressors. Aircol CM air compressor oils exhibit low carbon forming tendencies and meet the requirements of the DIN 51506 VDL classification for reciprocating air compressors having air discharge temperatures up to 220°C. For both oil flooded and oil injected rotary screw air compressors operating continuously at air discharge temperatures up to 90ºC, the product has been designed to meet service drain intervals of up to 4000 hours. For intermittent or continuous operation with air discharge temperatures above 90ºC, the manufacturers’ standard oil change periods should be used. The high FZG load carrying is designed also to meet geared air compressor units requirements. Selection of the required viscosity grade should be based upon the compressor manufacturers’ recommendation. However as a general guide, Aircol CM 32 and 46 are suitable for oil flooded rotary air compressors, whereas Aircol CM 68, CM 100 and 150 would be selected for lubricating the crankcase and cylinders of reciprocating air compressors. Aircol CM 150 is also recommended for sliding-vane air compressors, or for reciprocating units at high ambient temperatures. The Aircol CM range is fully compatible with Castrol Aircol PD and MR ranges. Aircol CM air compressor oil range is classified as follows: ISO 6743-3 Compressor Oils DAA and DAB for reciprocating (piston) and drip freed rotary air compressors DAG and DAH for oil-flooded rotary screw air compressors Specific grades within the Aircol CM air compressor oil range, meet the requirements of: Sauer Compressors, Hatlapa (Types L,V, VA and W), Yanmar, Sanwa, Matsubara, Tanabe, Teikuko, Dongwha Pnetec, Bumhan, Burckhardt (VSB 1001132 E01 02).

A. Castrol Aircol CM 68 is for reciprocating air compressors — industrial reciprocating compressors operating at elevated discharge temperatures where ISO VG 68 mineral compressor oil is specified.
A. Castrol Aircol CM 68 is ISO VG 68 — the heavier mineral compressor oil viscosity for higher-temperature reciprocating air compressor service.
A. Castrol Aircol CM 68 meets ISO 6743-3 (compressor oil classification); and DIN 51506 (industrial compressor oil specification).
A. DIN 51506 is the German industrial standard for lubricating oils for air compressors. It specifies the VBL, VCL and VDL performance classes, where VDL is the highest-tier specification for compressors with discharge temperatures up to around 220°C.
A. Both are Castrol Aircol CM mineral-oil air compressor lubricants in the same range and meeting ISO 6743-3 and DIN 51506. They differ only in viscosity grade: Aircol CM 46 is ISO VG 46 for lighter-duty general-service air compressors; Aircol CM 68 (this product) is ISO VG 68 for higher-temperature reciprocating compressor service.
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.
