the new SN maxlife is not resource conserving and is still a synthetic blend. This is what valvoline says
Thank you for your question. All products that were updated with the new ILSAC GF-5 specifications are still the same products, such as base oils, additives, etc., there have only been some alterations in the additives to help with deposit control and fuel economy. The original MaxLife products you are accustomed to using, will still perform perfectly fine and supercede the older GF-4 specifications.
