About Castrol Alpha SP 320
Castrol Alpha SP 320 is the ISO VG 320 grade of the Alpha SP mineral EP gear-oil range, which Castrol lists against AGMA 250.04, US Steel 224 and DIN 51517 Part 3.
Before you switch
If the gearbox OEM mandates DIN 51517-3 (CLP) or micropitting protection, IOCL lists Servomesh Plus (DIN 51517 CLP, AGMA 9005-D95, Flender AG, US Steel 224, David Brown S1.53.101). Ask us for the Plus grade in the same viscosity.
Changeover checklist
- Confirm viscosity and the gearbox OEM's performance class (e.g. DIN 51517-3 CLP, AGMA EP, micropitting requirement).
- Drain warm, flush heavily sludged boxes, and inspect gear flanks and breathers.
- Mineral EP gear oils are normally compatible. Never mix mineral with PAG synthetics.
- Refill to the sight-glass mark. Check temperature and noise after the first shift.
