From incoming raw materials to finished batches, US Global Petroleum combines on-site testing, retained samples, and published approvals to support consistent lubricant quality.
Test requirements vary by product and specification. The latest Product Data Sheet and applicable approval document remain the product-specific reference.

Key Checks Listed
Laboratory Testing
The current quality-control information identifies ten key checks covering fluid behavior, thermal characteristics, formulation chemistry, contamination, and product identity.
Fluid Behavior
These checks help confirm how the lubricant flows at defined temperatures and whether its measured viscosity aligns with the intended grade or formulation target.
What It Supports
Grade confirmation and expected flow behavior across temperature conditions.
Customer Reference
Review the product's viscosity grade and typical values in the current PDS.
A viscosity result is one part of product evaluation; it does not replace the full performance specification.
Verification & Evidence
Review the management-system documents, product licenses, approvals, test records, and technical files that support a purchase decision.
The current resource library publishes management-system certificates and API licensing documentation for review.
The current site provides product-specific evidence across API field tests, OEM or licensing records, and independent comparison reports.
Product Data Sheets explain applications, performance levels, and typical properties. Safety Data Sheets cover handling, storage, exposure, and emergency-response information.
Approval, license, and performance claim are different.
A statement that a product meets a performance level does not automatically mean every listed organization has issued a formal approval. Check the specific product, grade, license, approval document, and revision before making a specification decision.
Use Technical Resources to locate the current PDS, SDS, approval, certificate, or test report.
