KLÜBER to Mobil Compressor Oil Cross-Reference Table
| KLÜBER Product | Equivalent Product | Compatibility & Notes |
| Klubersynth RA 4-46 | Mobil Rarus SHC 1026 | Both PAO synthetic compressor oils. Klubersynth RA 4 series for rotary screw compressors. |
| Klubersynth RA 4-68 | Mobil Rarus SHC 1028 | Synthetic compressor oils for higher-temperature operation. Verify OEM-approved lubricant list. |
| Klubersynth RA 4-100 | Mobil Rarus SHC 1030 | Higher viscosity synthetic for demanding compressor applications. |

⚠ Important Disclaimer
This cross-reference is provided for informational purposes only. Equivalent does not mean identical — differences in thickener type, base oil viscosity, additive packages, and NLGI grade can affect performance. Always verify technical compatibility by consulting both manufacturers' datasheets and obtaining OEM approval before substituting lubricants. Contact KOEED for verified KLÜBER product recommendations matched to your specific application requirements.
> Tip
When cross-referencing, always verify: (1) thickener compatibility — mixing incompatible thickeners can cause grease to soften or harden, (2) base oil viscosity at operating temperature, (3) NLGI grade for proper consistency, (4) certification status (NSF H1, ISO 21469) for food-grade applications. If in doubt, contact KOEED for a verified recommendation.
Frequently Asked Questions
Q: How often should synthetic compressor oil be changed?
PAO synthetic compressor oils like Klubersynth RA and Mobil Rarus SHC typically support oil drain intervals of 6,000-8,000+ hours (vs 2,000-3,000 hours for mineral compressor oils). However, the actual interval should be determined by oil analysis — monitor acid number (TAN), viscosity, and oxidation levels to optimize the drain interval for your specific operating conditions.
