Mobil SHC 629 alternative
- Lubri-Loy
- Industrial EP Synthetic Gear Oil ISO 150
- Package
- 5 gal pail
If you buy Mobil SHC 629 in a 5 gallon pail, there is a straight swap on Lubri-Loy's interchange list: GOS-150-640, our Industrial EP Synthetic Gear Oil in ISO viscosity grade 150. It is a PAO (polyalphaolefin) synthetic built for enclosed gear drives that call for an AGMA EP or AGMA S gear oil, and you can order it direct from Lubri-Loy.
This page lays out what the two oils have in common, where the published numbers differ, and what to check before you switch. We only use figures from Lubri-Loy's own catalog and from the manufacturer's public data, and we mark anything we could not verify.

Check before you switch
Mobil says SHC 629 is approved by Siemens AG for use in Flender gearboxes. If your gearbox maker requires a named approval, or your warranty depends on one, confirm what the OEM specifies before you switch.
Mobil's published viscosity index (166) and pour point (-48°C) are better than the Lubri-Loy catalog values shown above, so compare against the operating temperatures in your application. If you are changing oils in a running gearbox, follow your OEM's drain and flush guidance, and do not mix synthetic gear oils from different makers in one sump without confirming compatibility.
