What is Base Oil SN 350? Base Oil SN 350 is a Solvent Neutral paraffinic mineral base stock with kinematic viscosity of 67–70 cSt at 40°C, classified as Group I or Group II under API base oil categories. The "350" designation refers to its approximate viscosity of 350 Saybolt Universal Seconds at 100°F. It is produced through solvent extraction, dewaxing and hydrotreatment, yielding a high-purity oil used as the backbone for hydraulic fluids, gear lubricants, engine oils, metalworking fluids and industrial lubricant formulations. Compare with adjacent grades: SN 150 (lighter) and SN 500 (heavier).

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.

Material Overview

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.

Cost Analysis

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.

Frequently Asked Questions

Base Oil SN 350 FAQ

What is Base Oil SN 350 used for?
Base Oil SN 350 is used as a base stock for manufacturing hydraulic fluids, gear oils, engine oils, compressor oils, metalworking fluids, cutting emulsions, transformer insulating oils, and rubber extender oils. Its balanced viscosity of 67–70 cSt at 40°C makes it suitable for both industrial and automotive lubricant formulations.
What is the viscosity of Base Oil SN 350 at 40°C?
The kinematic viscosity of Base Oil SN 350 ranges from 67 to 70 cSt at 40°C, measured according to ASTM D-445. At 100°C, the viscosity is between 7.5 and 9 cSt. The Viscosity Index falls between 90 and 100 per ASTM D-2270.
Is SN 350 a Group I or Group II base oil?
Base Oil SN 350 is available in both Group I and Group II classifications according to API base oil categories. Group II variants feature sulfur content below 0.03% and higher saturation levels achieved through hydrocracking or hydrotreatment refining processes.
What is the difference between SN 350 and SN 500?
The primary difference is viscosity: SN 350 has 67–70 cSt at 40°C while SN 500 has 95–110 cSt at 40°C. SN 350 offers better low-temperature flow and is ideal for general-purpose hydraulic fluids, gear oils and engine oil formulations. SN 500 provides thicker film strength for heavy-duty gear oils, marine engines and applications where maximum load protection is required.
How is Base Oil SN 350 packaged for export?
Base Oil SN 350 is available in 208L new steel drums (80 drums per 20ft container, 14.4 MT total), 1000kg IBC totes (18 per 20ft container, 18 MT), flexitanks (20–24 MT per 20ft container), ISO tank containers (20–25 MT), and bulk road tankers (30–35 MT). All containers are nitrogen-blanketed to ensure product integrity during international shipment.
What is the flash point of Base Oil SN 350?
The flash point of Base Oil SN 350 is 220–230°C per ASTM D-92 (Cleveland Open Cup method). This classifies it as a combustible liquid with safe handling characteristics for standard industrial applications.
What is the shelf life of Base Oil SN 350?
When stored in sealed containers below 50°C in a cool, dry location away from direct sunlight, Base Oil SN 350 maintains its specifications for 24 months. Proper FIFO (first-in, first-out) inventory rotation and monthly visual checks for water contamination or sediment are recommended for bulk storage tanks.
Can Base Oil SN 350 be used for engine oil production?
Yes, SN 350 is commonly used as a base stock for standard-duty gasoline and diesel engine oils, particularly in API SN and lower performance categories. It provides good solubility for detergent-dispersant and anti-wear additive packages. For high-performance or extended-drain applications requiring API SP or higher, Group III or synthetic base oils are typically recommended.
What is the pour point of Base Oil SN 350?
The pour point of Base Oil SN 350 is 0°C per ASTM D-97. This indicates adequate low-temperature flow characteristics for moderate climate applications. For arctic or sub-zero operating environments, pour point depressant additives can be blended, or a lighter grade such as SN 150 may be more appropriate.
How much does Base Oil SN 350 cost per ton for bulk export?
Base Oil SN 350 pricing varies based on order volume, packaging type, destination port and current crude oil market conditions. Bulk flexitank and ISO tank shipments typically offer the lowest per-ton delivered cost. Contract pricing with fixed or floating terms is available for regular volume buyers. Contact a Base Oil SN 350 supplier directly for a competitive quote tailored to your specific requirements and logistics.
