Castrol Carelube HTG
Castrol Carelube HTG is formulated from natural vegetable oils to be more environmentally acceptable than traditional mineral–based hydraulic fluids. Since hydraulic systems are prone to leakage due to high pressures, Castrol Carelube HTG is an excellent hydraulic fluid in applications where leakage could cause water or soil contamination. It can be counted on for the following performance benefits:
Formulated from natural vegetable oils, Castrol Carelube HTG is more than 99 percent biodegradable as measured in the CEC L–33–T–82 tests. Tests indicate that it is capable of being decomposed by biological agents within 120 hours, unlike mineral oil, which may remain intact for much longer, polluting water and soil. Castrol Carelube HTG is recommended for outdoor applications where leakage could result in soil or ground water contamination and substantial fines or claims for damage on the responsible operator. (Spills, however, must be handled the same as for mineral–based fluids.)
Low Toxicity
In addition to its biodegradability, Castrol Carelube HTG has a very low toxicity before, during and after breakdown. This reduces the threat to bacteria, fish and humans coming in contact with contaminated water.Stay–in–Grade Performance
Castrol Carelube HTG has a very high viscosity index (VI) of 200. Standard mineral hydraulic oils have VIs of around 100. This extra high VI means that Castrol Carelube HTG experiences little change in viscosity during its recommended operating range of 0°F to 175°F. Castrol Carelube HTG is also very shear stable which means that it resists breakdown during high shear applications.Anti–wear Performance and High Lubricity
Due to its special formulation, Castrol Carelube HTG is inherently a better lubricant than standard mineral–based counterparts. This high lubricity accounts for reduced wear and less fuel consumption due to more efficient operations. Castrol Carelube HTG also contains an anti–wear package that increases its load–carrying abilities.Spills, Clean–Up and Disposal
Although biodegradable, Castrol Carelube HTG must still be cleaned up when spilled. Spill prevention and clean up efforts are the same for Castrol Carelube HTG as for other mineral hydraulic fluids. All oil spills are reportable to the National Response Center and/or state and local government agencies. From a disposal standpoint, it is advisable to segregate waste Castrol Carelube HTG from other waste oils, which if mixed with Castrol Carelube HTG, could render it hazardous and eliminate less costly disposal options.
