Simple question asked..."is your Havoline Synthetic 5w-30 a group III or group IV/V base stock motor oil?"
Response;
"Thank you for contacting ChevronTexaco. We do not release proprietary formula information. Please be aware that the ultimate performance of a synthetic motor oil rests with a carefully balanced blend of the synthetic base stock and the additive package used. Chevron Supreme Synthetic Motor Oils and Havoline Synthetic Motor Oils are both blended with additive packages that will provide premium performance."
Is being a G III or G IV really a mission critical formulation secret? Evidently yes.
