Castrol Optigear Synthetic™ 1710/320 is a high-performance extreme pressure gear oil (ISO VG 320) formulated with Castrol’s Tribol Gear Oil Additive (TGOA) Plastic Deformation (PD) additive and high-quality mineral base oils and synthetic polyalphaolefins to help tackle wear-related problems in heavily loaded industrial gears and bearings.
- Pack size: 20 L canister
- Also available in: 208 L drum
Applications
- Spur, helical, herringbone, bevel and planetary gears; geared couplings; rolling and sliding bearings; gear drive circulating systems
- Usable temperature range (application dependent): −30 °C to +95 °C (−22 °F to 203 °F)

Approvals & Specifications
- Classification: CLP-HC (DIN 51502); exceeds DIN 51517 T.3
- Compatibility: compatible with most mineral oil, ester and synthetic-based products (up to ~3% residual without issues); not compatible with polyglycols
Features
- TGOA PD enables micro-smoothing of surface roughness under activation energy, delivering very low friction and optimum wear protection
- Protects against scuffing and shock loading; high load-carrying capacity
- Can help prevent progression of micro-pitting in pre-damaged gears
- Lower operating temperature and noise; extended service life of gears and bearings
- High viscosity index: easier cold start-up and sufficient film at high temperatures
- Running-in pitting is prevented or stopped; lapping often unnecessary; previous pitting/damage can be halted or visibly reduced

Application notes
- For mixed fills, small residuals (~≤3%) of previous mineral/ester/synthetic oils are acceptable; performance benefits of TGOA PD may be reduced when mixed.
- Not compatible with polyglycols. After draining a polyglycol fill, flush thoroughly with mineral oil or flushing oil before filling.
- Observe the recommended operating temperature range and OEM specifications.
