E8018-G is general low alloy steel electrode means no fixed chemical composition requirements for all the alloying elements until or unless agreed between the supplier and purchaser. You should not be using this in place of E8018-C1 or E8018-W2.
Like E8018-C1 requires at least 2% Ni versus only 0.5% min. specified in E8018-G.
(attached find the chemical requirements of E8018-C1 and E8018-W2)
