Amsoil announces the reformulation of its Extended Life XL Synthetic Motor Oils, now available in four different viscosities with a bold new packaging design. The new XL oils contain Extended Drain Boost for longer service life in keeping with the lengthening oil change intervals of newer cars. XL has been formulated to meet the more stringent ILSAC GF-5 and API SN service categories and offers better engine protection for reduced maintenance costs in gasoline engines. Amsoil XL Synthetic Motor Oils employ an extra treatment of alkaline additives added to premium synthetic base stocks to neutralize acids. The extra additive package effectively raises the total base number (TBN) and resists shear to provide superior performance throughout the entire drain interval of up to 10,000 miles or six months, whichever comes first.
