About Us

Peter Seibert retired in 1965, and his son, Howard Seibert partnered with William Avery to form the Avery Company. In 1968, Mr. Avery retired to the central coast and Howard Seibert renamed the Company to Seiberts' Oil Company. Seiberts' Oil then became a California Corporation in 1978.   

After Howard Seibert retired in 1981, his two sons, Craig and Douglas Seibert, acquired the stock of the corporation, making Craig Seibert company President, and Douglas Seibert Secretary and Treasurer.  We continue with a tradition of excellent service, providing petroleum fuels and motor oils to customers in the Central San Joaquin Valley, with our target market being commercial sales, agriculture, and retail stations.
