Our Tenacious Oil is used for ultimate protection and durability for components that have movement with metal-to-metal contact. Our base oil has been produced for us by the same independent California refinery since 1971. The final blending of rust inhibitors and extreme wear additives happens at our facility before the product is bottled and shipped.
