SUNOCO ULTRA SYNTHETIC dexos1™ Gen 3 SP/GF-6A ENGINE OILS are the latest iteration in advanced protection for your gasoline-fueled GM vehicles. These premium synthetic motor oils are specifically designed to inhibit LSPI (low speed pre-ignition), an engine event which can cause premature engine wear or catastrophic engine failure in GDI (gas direct injected) and turbo-boosted engines. Their proprietary formulas of high-performance synthetic base stocks and advanced additive system are specifically engineered for turbocharged direct-injected gasoline vehicles operating in low-speed and high-load driving conditions. SUNOCO ULTRA SYNTHETIC dexos1™ Gen 3 SP/GF-6A ENGINE OILS are licensed and approved by General Motors. These lubricants are designed to perform under extreme conditions, have excellent cold temperature properties, resist thermal breakdown, and exceed the performance requirements of API SP and ILSAC GF-6A licensing categories and are now recommended against Ford Motor Company's LSPI specifications Ford WSS-M2C962-A1 and Ford WSS-M2C961-A1.
SUNOCO ULTRA SYNTHETIC dexos1™ Gen 3 SP/GF-6A ENGINE OILS are formulated to protect against LSPI events and are scientifically proven to provide superior engine protection longer than standard SP GF-6A products. These oils are exceptionally shear stable, have extremely low volatility resulting in less oil burn off at high temperatures, and contain robust anti-oxidation technology and detergency. The advanced additive system in SUNOCO ULTRA SYNTHETIC dexos1™ Gen 3 SP/GF-6A ENGINE OILS ensures excellent protection against sludge and varnish, makes them highly resistant to foaming, corrosion, and thermal breakdown, while improving overall oil film strength for greater wear protection and a lower coefficient of friction to improve fuel economy.
