Castrol Aircol LPT 68 is an ISO VG 68 naphthenic mineral refrigeration compressor oil in the Castrol Aircol LPT range. Castrol positions the range for refrigeration compressors using traditional refrigerants, particularly ammonia and CFC/HCFC refrigerants. The supplied product photographs show both a 20 L pack and a 208 L drum.
This product page is for maintenance and procurement teams replacing a documented Aircol LPT 68 charge or sourcing a specified naphthenic refrigeration oil. The compressor manual and current lubricant document remain the final source for model-specific oil approval.
| Item | Available Information | Buyer Check |
|---|---|---|
| Brand / Product | Castrol Aircol LPT 68 | Match the complete product name on the current container or compressor-service record. |
| Former naming | BP Energol LPT 68 | Use the former name only as a cross-reference clue; confirm the current manufacturer documentation before substituting. |
| Oil family | Naphthenic mineral refrigeration compressor oil | Confirm the required chemistry; do not select by viscosity alone. |
| ISO viscosity grade | ISO VG 68 | Confirm the required grade and reference temperature in the compressor documentation. |
| Reference packages | 20 L pack and 208 L drum shown in supplied images | Confirm current availability, pack count and freight details before order release. |
| Traditional refrigerants | Castrol identifies the Aircol LPT range as suitable for ammonia and CFC/HCFC refrigeration applications. | Verify the exact compressor model, materials and operating conditions. |
The following values are taken from the supplied working reference file. They are useful for quotation comparison and incoming-document checks, but are not stated here as a batch guarantee. Use the current Castrol TDS and any required certificate for the final purchase decision.
| Property | Reference Value | Test Method / Buyer Meaning |
|---|---|---|
| Base oil type | Highly refined naphthenic mineral oil | Oil-family check before replacement or top-up |
| ISO viscosity grade | ISO VG 68 | Viscosity-class reference |
| Kinematic viscosity at 40°C | 69.0 mm²/s | ISO 3104 / ASTM D445 reference |
| Kinematic viscosity at 100°C | 7.3 mm²/s | High-temperature viscosity comparison |
| Pour point | -36°C | ISO 3016 / ASTM D97 reference |
| Density at 15°C | 900 kg/m³ | ISO 3675 / ASTM D1298 reference |
| Flash point, COC | 185°C | ISO 2592 / ASTM D92 reference |
| Total acid number | 0.01 mg KOH/g | ISO 6618 / ASTM D974 fresh-oil reference |
| System context | Screening direction | What must be confirmed |
|---|---|---|
| Ammonia / R717 refrigeration | Castrol describes the Aircol LPT range as particularly suitable for traditional refrigerants including ammonia. | Compressor model, oil-separator arrangement, required viscosity, temperatures and OEM oil requirement. |
| CFC / HCFC refrigeration | Castrol describes the range as suitable for traditional CFC/HCFC applications. | Identify the precise refrigerant, compressor and any conversion or service history. |
| Legacy R22 systems | May be evaluated only where the equipment specification calls for an appropriate mineral refrigeration oil. | Original oil, retrofit history, approved grade and compressor documentation. |
| HFC / HFO systems | Do not assume this mineral-oil product is the correct fit simply because it is a refrigeration oil. | Use the compressor and refrigerant documentation to identify the required oil family, often a specific synthetic oil where specified. |
| Unknown or mixed-oil history | Not suitable for a brand-name-only top-up decision. | Identify the oil already in service and obtain a documented changeover procedure. |
| Reference package | Typical use | Control point |
|---|---|---|
| 20 L pack | Planned service work, contractor stock or smaller maintenance requirements. | Check that the volume covers the approved service procedure and handling loss. |
| 208 L drum | Plant maintenance inventory, distributor stock or larger shutdown planning. | Confirm lifting, storage, traceability, dispensing equipment and delivery conditions. |

Castrol Aircol LPT 68 is an ISO VG 68 naphthenic mineral refrigeration compressor oil in the Aircol LPT range. It is used where the compressor and refrigerant documentation calls for this oil type and grade.
BP Energol LPT 68 is a former reference name associated with the Aircol LPT range. Use it as a cross-reference cue, then verify the current Castrol documentation and product label before placing an order.
Castrol describes the Aircol LPT range as particularly suitable for traditional refrigerants including ammonia. The exact compressor model, operating conditions and OEM requirement still control the final decision.
It may be evaluated for legacy R22 equipment where an appropriate mineral refrigeration oil is specified. Check the compressor manual, current oil and retrofit history before purchase.
Do not select this mineral refrigeration oil from refrigerant name alone for an HFC or HFO system. Confirm the specified oil family and grade in the compressor and refrigerant documentation.
The supplied product images show a 20 L pack and a 208 L drum. Actual supply, labeling and freight details should be confirmed in the quotation.
Request the current TDS, SDS, package label and any required batch or certificate documentation, together with a response tied to the compressor model and application.
First-party supply evidence: the three supplied product images support visible packaging and product-name claims. Supplied technical reference: the property table is a working reference only and must be checked against current manufacturer documents. Final approval: the compressor/OEM documentation governs the exact lubricant choice.
