United Eco-Elite (LSPI) is a fully synthetic passenger car motor oil with technology designed to provide an upgrade in performance to meet the latest requirements for GM specifications. United Eco-Elite (LSPI) is formulated to meet the severe performance demands of the latest turbocharged gasoline direct injection (TGDI) engine technology including new test requirements to prevent turbocharger failure, control the potential issues associated with oil aeration and to reduce the potential for engine damage due to pre-ignition. This new specification is introduced by GM in advance of the new ILSAC GF-6 category and also includes more severe demands in terms of oil oxidation performance and oil volatility. Although the specifications are listed with difference viscosity grades, it has the provision for the future inclusion of SAE 0W-16 grades, the main viscosity grades recommended by GM will be SAE 5W-30 and 0W-20.
