SN500 Mineral Base Oil
SN500 is a mineral base oil grade with a generally higher viscosity profile than SN350. It may be evaluated as a raw-material component for selected gear oil, grease, marine lubricant and industrial oil formulations, subject to buyer specifications and technical approval.

What is SN500 base oil?
SN500 is a base-stock grade, not a ready-to-use lubricant. Higher viscosity does not automatically mean better quality. The required base oil profile is determined by equipment operating conditions, target finished-oil viscosity, additive compatibility and applicable performance requirements.
Potential applications
Gear lubricants: Higher-viscosity base stocks may be evaluated for certain formulations; extreme-pressure and other performance properties depend on the completed formulation.
Grease manufacturing: Base-fluid viscosity is a relevant formulation input. Grease consistency is influenced independently by the thickener system, so using SN500 does not by itself define an NLGI grade.
Marine lubricants: Mineral base stocks are used in selected marine lubricant formulations. A particular SN500 batch must be qualified against the lubricant manufacturer's specification and any required finished-product approvals.
Industrial oils: May be assessed where a higher-viscosity base stock helps meet the planned formulation, subject to technical testing.
Technical assessment
Buyers commonly review viscosity at 40°C and 100°C, viscosity index, flash and pour points, density and other grade-specific properties:
| Technical parameter | Role in the purchasing assessment |
|---|---|
| Viscosity at 40°C and 100°C | Core inputs for reaching the formulation's target viscosity. |
| Viscosity index | Viscosity behaviour as operating temperature changes. |
| Flash and pour point | Process, safety and low-temperature requirements. |
| Density, colour, water and sulphur | Batch control and comparison with the buyer's specification. |
| Additive/formulation compatibility | Assessment of the finished lubricant's performance. |
Technical documentation: Only verified, approved commercial technical documentation should be used to publish batch values. The scope of available documents and sample arrangements is explained during discussion.

SN500 FAQ
- Is SN500 higher quality than SN350?
- Not by definition. These are different viscosity grades.
- Can SN500 be used directly as grease?
- No. Grease is formulated using base fluid, thickener and, where needed, additives.
- Can SN500 be used in marine lubricants?
- It may be assessed for suitable formulations; technical acceptance is required.
- Is there a published minimum order quantity?
- Commercial quantities are clarified in the quotation process, not assumed on the website.
- What should I include in my enquiry?
- Intended application, target specifications, quantity and delivery requirements.
