Phil Wood 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. Final blending of rust inhibitors and extreme wear additives happen at our facility before the product is bottled and shipped.
Every shop should have a bottle of Phil's Tenacious Oil, whether you're a pro or have a home shop.
American made in USA.
