Engine oils need to be able to constantly respond to the ever-changing environments in your engine. Every second of the drive your engine oil needs to be able to react to the needs of different metal-to-metal contact points in your engine each with different demands, pressures and temperatures. Castrol EDGE provides the highest level of protection for critical engine parts helping your car to perform at its maximum. A new oil technology from Castrol, Fluid Titanium Technology, doubles the strength of Castrol EDGE.* It's now three times stronger against viscosity breakdown than conventional oil (Mobil 1 EP).** The unique titanium technology physically changes the way oil behaves under extreme pressures. In industry standard tests, Castrol EDGE with Fluid Titanium has doubled its film strength, preventing oil from breaking down and reducing friction to maximize engine performance.
*Based on the ASTM HFRR Friction Test
**Tested in 5W-30 versus all major conventional brands in Kurt Orbahn Test
*** Compared with industry IIIG WPD (high temperature deposit) requirements.
**** Based on ACEA A/B specification. Castrol EDGE 5W-30 meets Europe's ACEA A/B specification while Pennzoil Platinum 5W-30 and Valvoline SynPower 5W-30 do not.
Engine oils need to be able to constantly respond to the ever-changing environments in your engine. Every second of the drive your engine oil needs to be able to react to the needs of different metal-to-metal contact points in your engine each with different demands, pressures and temperatures. Castrol EDGE Extended Performance with Titanium FST provides unsurpassed protection for critical engine parts, ensuring optimal performance - with the strength to enable an extended drain interval of up to 15,000 miles. Independent testing has proven EDGE Extended Performance stronger than Mobil 1 Extended Performance against viscosity breakdown - the ultimate test of strength.*
* Castrol EDGE Extended Performance 5W-30 was proven stronger against viscosity breakdown based on ASTM 6278 and CEC-L-14 independent testing
** If your vehicle is under warranty, follow the oil change interval recommended by your manufacturer. Extended service is not recommended in severe service applications such as racing, frequent towing or hauling, commercial use, extremely dirty/dusty conditions or excessive idling.
Trishield™ is a unique triple-action technology that attracts, captures and disperses particles that can build up in engines and causes sludge build-up. TriShield stops small particles from becoming big problems, and protects the car you rely on. This innovative technology uses a polymer that contains two chemical hooks that attract and capture both sludge and soot in a single molecule, helping to prevent particles from building up. With TriShield Technology, Castrol has improved the potency and protection that GTX provides.
Conventional oils may not do enough to protect high-mileage vehicles. As the miles add up, Castrol GTX High Mileage helps extend engine life by addressing the key problems that may impact your vehicle. As an engine gets older, gaskets become brittle, seals deteriorate and oil burns faster. Castrol GTX High Mileage with Trishield Technology helps extend engine life by providing superior protection against sludge build up.*

Castrol GTX SynBlend is a premium synthetic blend motor oil specially engineered with Trishield Technology to provide maximum wear protection. Trishield actively protects against particles that build up in car engines with the most advanced sludge-fighting ingredients.
Modern engine technology is focused on getting more power out of smaller engines. This results in more heat and stress on key engine components, which can make newer engines more vulnerable to sludge and wear. GTX SynBlend cools critical engine parts providing a superior level of protection against wear and oil burn-off.
 In Sequence IVA wear test and Sequence VG test.
 In 5W-30 grade only. Dexos is a trademark of the General Motors Co.
