Description
Castrol GTX Ultraclean motor oil features TriShield for superior sludge protection. TriShield is a unique triple-action technology that attracts, captures, and disperses particles that can build up in engines and causes sludge buildup. It 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.
