It serves as the primary base stock for hydraulic fluids, gear oils, engine oils and metalworking lubricants — delivering reliable performance at significantly lower cost than synthetics. As an experienced Base Oil SN 350 supplier, we deliver this grade in drums, flexitanks and ISO tanks worldwide. Explore our full base oil product range.
Why SN 350 Is the Most Widely Specified Base Oil Grade
SN 350 occupies the sweet spot between viscosity, cost and performance — making it the default choice for lubricant blenders worldwide.
Balanced viscosity profile
At 67–70 cSt, SN 350 provides sufficient film strength for gear and hydraulic applications while maintaining good low-temperature flow characteristics.
Best cost-performance ratio
Delivers approximately 85–90% of synthetic base oil performance at 40–60% lower cost per ton, making it ideal for high-volume lubricant production.
Superior additive compatibility
Accepts 15–25% additive treat rates without solubility issues. Compatible with ZDDP, detergents, dispersants and all major additive packages.
Global supply availability
As the most traded solvent-neutral grade, SN 350 benefits from established supply chains, multiple packaging formats and competitive export pricing.
What Is Base Oil SN 350?
Base Oil SN 350 is a light-to-medium viscosity lubricant base stock produced through solvent extraction and dewaxing of vacuum distillates. The "SN" designation stands for Solvent Neutral, referring to the refining process that removes aromatic compounds, polar impurities and wax to yield a high-purity paraffinic oil. The number "350" indicates its approximate viscosity of 350 Saybolt Universal Seconds (SUS) at 100°F, which corresponds to 67–70 cSt at 40°C.
According to API base oil classification, SN 350 falls under Group I (when sulfur exceeds 0.03% and saturations are below 90%) or Group II (when sulfur is below 0.03% with saturations above 90%, achieved through hydrocracking or hydrotreatment). This dual-classification versatility makes it one of the most widely traded base oil grades in global petroleum markets.
As a leading Base Oil SN 350 supplier, we deliver this premium paraffinic base stock with consistent batch-to-batch quality, ensuring reliable blending results for lubricant manufacturers and blenders across Asia, Africa, the Middle East and beyond.

SN 150 vs SN 350 vs SN 500 — How to Choose the Right Grade
When evaluating a Base Oil SN 350 supplier, understanding how SN 350 compares to adjacent grades ensures you source the right viscosity for your formulations.
| Performance Characteristic | SN 150 (Light) | SN 350 (Medium) | SN 500 (Heavy) |
|---|---|---|---|
| Viscosity @ 40°C | 28–32 cSt | 67–70 cSt | 95–110 cSt |
| Viscosity @ 100°C | 5.0–5.5 cSt | 7.5–9.0 cSt | 10.5–11.5 cSt |
| Typical Applications | Spindle oils, light hydraulics, low-viscosity engine oils | General hydraulics, gear oils, engine oils, metalworking fluids | Heavy-duty gear oils, marine engines, industrial lubricants |
| Low-Temperature Flow | Excellent | Very Good | Moderate |
| Additive Response | Good solubility | Superior compatibility | Good high-treat-rate stability |
| Film Strength | Light load protection | Moderate to heavy load | Maximum EP protection |
| Cost Position | Most economical per liter | Best cost-performance ratio | Premium mineral grade pricing |
SN 350 vs Group III & Synthetic Base Oils
Understanding where SN 350 delivers value — and where it reaches its limits — is essential for cost-optimized lubricant formulation.
Where SN 350 Excels
- Delivers 85–90% of synthetic performance at 40–60% lower cost per ton
- Extended equipment life through stable lubricating films under normal conditions
- Oxidation resistance supports standard-duty drain intervals
- Accepts 15–25% additive treat rates without haze or separation
- Compatible with all major additive packages including ZDDP
- Predictable viscosity blending for custom ISO VG formulations
- Lower internal friction reduces power consumption in hydraulics
When to Consider Group III / PAO
- Continuous operating temperatures exceeding 120°C
- Extended drain intervals beyond 10,000 hours required
- Extreme cold-start conditions below –20°C ambient
- OEM specifications mandating synthetic base stocks
- Applications requiring VI above 120 for wide temperature range
- Food-grade or pharmaceutical-grade lubricant requirements
Practical approach: Many lubricant manufacturers blend SN 350 with a percentage of Group III or PAO to achieve a cost-effective balance between performance and price.
