TRISHIELD™ TECHNOLOGY FOR SUPERIOR SLUDGE PROTECTIONTriShield™ 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.
