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.

Product Features:
  • Unique TriShield technology actively protects against particles that build up in car engines with the most advanced sludge-fighting ingredients
  • Castrol GTX uses premium, custom-made additives and is the most advanced conventional oil available
  • Maximum protection against viscosity and thermal breakdown
  • Extreme detergency action helps prevent deposits
  • Exceeds API Service SM, SL, SJ and SH; ILSAC GF-4/GF-3/GF-2 for API Certified Gasoline Engine Oils; meets Energy Conserving Standards; GM6094M
  • Exceeds demanding US high-shear and stay-in-grade requirements for viscosity breakdown protection

              • Q:

                Is this compatable with a motorcycle using a wet clutch system. I have a Honda Pacific Coast (PC-800). The motor oil is also used in the wet clutch. Thanks in advance

                  A:

                  I'm glad to assist, Mike! Castrol does not recommend using passenger car motor oils in motorcycles. In 1996 the American Petroleum Institute (API) upgraded the performance standards of motor oil from SG to SJ (currently SN). This upgrade impacted the friction modifiers and zinc and phosphorus levels to address the fuel economy, catalytic converter and emissions issues of passenger cars. For motorcycles, the additional friction modifiers can affect wet clutch performance, and these engines typically require a higher level of the anti-wear additives (zinc and phosphorus). For an air cooled motorcycle, Castrol recommend a V-Twin formulation - Castrol Power RS V–Twin. For the liquid-cooled, either V-twin or 4 stroke would be appropriate, and your choice should be based on the viscosity requirements of the motorcycle - Castrol Actevo X–tra and Castrol Power RS Racing.
