Castrol EDGE with SYNTEC Power Technology was pitted against the leading synthetic oil manufacturers in an extreme test of maximum torque. To no one's surprise, Castrol emerged victorious, proving that when it comes to synthetic oil, it's far and ahead of the competition.

So what makes Castrol EDGE a lot better? Well, for starters, this special oil has a unique formula that reduces volatility and provides superior protection for critical engine parts helping your vehicle operate efficiently at maximum power.

On top of that, the Castrol EDGE with SYNTEC Power Technology also delivers 42% better rating on fighting power-robbing deposits, superior engine protection against corrosive particles ans superior performance on deposit, wear and oxidation.

It also neutralizes those acids in the engine that can cause rust and corrosion on vital parts, including the cylinders, bearings and hydraulic valve lifters. The oil also improves stability and endurance under extreme conditions (heat, load, speed). But the best part? The EDGE can be used with confidence in every gasoline-engine passenger car, new or old, regardless of oil previously used.
