A synthetic zeolite, designated zeolite GZS-11, is made having a molar composition expressed by the formula: [x M.sub.2/n O+(1.0.+-.0.2-x)R.sub.2/n O]:Y.sub.2 O.sub.3 :y XO.sub.2 :w H.sub.2 O where M is an inorganic cation of valance n, R is an organic cation of valence n, "x" has a value of less than 1.0, Y is one or more of +3 valence elements, such as aluminum, boron, gallium, iron, chromium, vanadium, molybdenum, or manganese, X is one or more of +4 valence elements, such as silicon, germanium, or titanium, "y" has a value of between 6 to 25, "w" has a value of up to 4 depending upon the degree of hydration of the zeolite, and having an X-ray diffraction pattern of the as-synthesized zeolite substantially as in Table 1. The method for making the low ratio of XO.sub.2 /Y.sub.2 O.sub.3 such as SiO.sub.2 /Al.sub.2 O.sub.3 is achieved by adjusting the synthesis mixture composition during the aging stage through the addition of one or more of the solutions containing the reactive sources of zeolitic components.
