Here it is folks...Castrol Syntec SAE 0W-30 motor oil. This is the European formula that is "Made in Germany" and is engineered to meet the Mercedes Benz 229.5 specification. The 0W-30 viscosity grade is ideal for winter conditions where low temperature pumpability is required. A unique, low-temperature formulation provides exceptional pumpability in cold weather and allows for unaided engine starts down to -40?F. Exceeds all car and light truck manufacturer's warranty requirements for the protection of gasoline, diesel and turbocharged engines where API SL, SJ, SH, CF or CD is recommended.

German Castrol has been completely analyzed in order to determine the nature of it's base oil. It uses an extremely exotic base oil which is 100% fully synthetic, extremely shear stable and uses no polymer viscosity index improvers. Under several lab oil analysis tests, this oil is superior to Mobil 5W-30 oil. It has been heard to increase oil pressure as well as reduce engine tick and piston slap in the LS1 engines. Castrol Syntec Delivers:

• An advanced package that neutralizes corrosive particles, preventing them from grouping together and forming power-robbing sludge.
• Stability and edurance under extreme conditions (heat, load, speed) that can cause conventional oils to break down.
• Superior engine protection that outperforms leading conventional and synthetic blend oils, passing severe industry torture tests.
