Phil Wood Tenacious Oil is used for ultimate protection and durability for components that have movement with metal-to-metal contact.

Phil Wood's base oil has been produced for us by the same independent California refinery since 1971. Final blending of rust inhibitor and extreme wear addititves happen at their facility before the product is bottled and shipped.

Tenacious Oil is offered in a 4 oz. bottle.
