Synthetic Thermally Stable Biodegradable Hydraulic Oil
(ISO 32/46, SAE 5W-20)
AMSOIL TBI hydraulic oil is a premium lubricant designed to biodegrade to its natural state when subjected to sunlight, water and microbial activity. TBI has a very low toxicity level because the oil is formulated with ashless additives that do not contain heavy metals. TBI incorporates very high quality synthetic base oils that provide thermal stability, even though they are biodegradable. This oil also contains antiwear additives that have been thoroughly tested and qualified against stringent hydraulic oil standards.

Package sizes include:

5-Gallon Pail
55-Gallon Drum

PRODUCT DESCRIPTION
AMSOIL TBI hydraulic oil is a premium lubricant designed to biodegrade to its natural state when subjected to sunlight, water and microbial activity. TBI has a very low toxicity level because the oil is formulated with ashless additives that do not contain heavy metals.

AMSOIL TBI incorporates very high quality synthetic base oils that provide thermal stability, even though they are biodegradable. This oil also contains antiwear additives that have been thoroughly tested and qualified against stringent hydraulic oil standards including Denison HF0, HF1, HF2, Vickers M-2950-S, I-286-S, and Cincinnati Milacron P-68 and P-70. TBI provides optimum protection for your hydraulics because it prevents wear of the pump and prevents rust of critical components. TBI contains antioxidants that increase the life of the oil and it contains foam inhibitors that quickly release air from the oil.

TBI outperforms vegetable oil-type, biodegradable hydraulic oils because it is based on high-quality, synthetic oil chemistry that lasts longer and withstands heat better. This ensures problem-free operation.

• Prevents Rust and Foam
• -51°F Pour Point For Cold Temperature Performance
• Outperforms Vegetable Type Bio-Hydraulic Oils

APPLICATION RECOMMENDATION
AMSOIL TBI is recommended for gear, vane and piston stationary and mobile hydraulic systems. TBI is a multi-viscosity, SAE 5W-20 oil and is recommended for use in place of either ISO-32 or ISO-46 hydraulic oils.

TBI is essentially compatible with typical hydraulic oils and small amounts of contamination (lines, residue) is acceptable. However, it is recommended that systems be drained prior to installing TBI. Excessive system contamination will minimize its biodegradability effectiveness. 

TBI is especially well suited for applications where environmental contamination due to leaking or blown hydraulic lines presents an environmental hazard.

TBI has been tested and found compatible with Nitrile (Buna-N), Poly Acrylate, Flourocarbon (Viton) and Silicone seals which are commonly found in hydraulic systems. Consult your AMSOIL sales representative or AMSOIL INC. when dealing with systems containing seals not listed.

The ability of TBI to extend drain intervals and excel in performance is subject to operating conditions and maintenance practices. Monitoring by oil analysis is recommended.
