What are the differences between the oil products (GTX, SYNTEC, Edge….)?
Castrol GTX, with its unique shear stable viscosity improvers, exceeds demanding U.S. high shear and stay-in-grade requirements for viscosity breakdown protection. Rapid acceleration, sudden stops and highrevving all push your engine to work harder and run hotter. The extreme stress and searing heat generated from this hard driving can shear and volatilize oil, leading to viscosity and thermal breakdown.
The highest North American standard of protection against viscosity breakdown. Advanced anti-wear additives to help extend engine life. Superior detergency action to help prevent deposits.
Castrol GTX exceeds passenger car and light truck manufacturers’ warranty requirements for the protection of gasoline and turbocharged engines where API SM, SL, SJ or SH is recommended. GTX grades are formulated to exceed the engine protection requirements of Ford ESE-M2C153-G and F, GM 6085M, Chrysler MS-6395M.
SYNTEC provides superior protection against deposits. Corrosive particles such as acid, soot and oxidized fuel fragments can cause costly damage to critical engine parts. SYNTEC contains a Powerful Additive Package that neutralizes corrosive particles, preventing them from grouping together and forming sludge. Neutralizes acids in your engine that can cause rust and corrosion on vital engine parts such as cylinders, bearings and hydraulic valve lifters. SYNTEC meets the world’s toughest gasoline engine protection requirements. SYNTEC provides Stability & Endurance under extreme conditions (heat, load, speed) that can cause conventional oils to break down. SYNTEC delivers the ultimate performance under high-temperature conditions: unsurpassed protection against volatility burn-off and viscosity increase. SYNTEC can be used with confidence in every gasoline engine passenger car, new or old, regardless of oil previously used. SYNTEC is fully compatible with all conventional and SYNTEC offers a level of protection that Outperforms All Leading Conventional Oils, passing severe industry torture tests.
Edge is a completely different formula from SYNTEC that contains a different mix of base oils and additives. Edge meets the GM4718M specification and offers guaranteed protections for up to 15,000 miles, or one year, whichever comes first.* Finally, Edge provides unsurpassed engine wear protection that no leading synthetic oil, not even Mobil 1, can beat. This has been proven in industry tests conducted at an independent testing facility.**
*Guarantee excludes severe service applications such as frequent towing and hauling, racing dirty conditions and extreme idling. If your vehicle is covered by a warranty, follow your car manufacturer’s recommended oil change/service intervals, which can be found in your owner’s manual.
**Results based on Sequence IVA wear test.
