A medium-heavy viscosity oil that is well suited for horns with older or otherwise cranky valves. New and improved, Berp BioOil is made from sustainably grown sugarcane. The oil is plant-based, non-toxic, petroleum free and contains essential oil that cleans as it lubricates. The oil is clear and will not thicken or become gummy or sticky with age. This oil has a viscosity (cSt rating) of 5.6, which places it at the same thickness as the original BioOil. 8 oz studio bottle. Made in USA.
Refill for No 8 Rotor Valve Linkage, and No 11 Key oils.
