1、This diesel engine oil additive contains quality detergent additives and soot dispersant, which significantly improves detergency at high temperatures.
2、A thoughtful combination of high-temperature antioxidants and anti-oxidation and anti-corrosion additives ensures precise control of the engine oil base number (TBN): acidic combustion products are effectively neutralized, and the engine is reliably protected from corrosion.
3、The product is suitable for formulations of heavy diesel oils of classes CI-4 and below: the oil base number (TBN) reserve is maintained sufficiently, the antioxidant and anti-wear properties remain at a high level, and the oil change interval is extended.
T3259 is an additive package for heavy diesel motor oils, designed specifically for oils of the CI-4, CH-4 and CF-4 classes. It contains high-quality detergent additives, soot dispersant, anti-oxidation-anti-corrosion and high-temperature anti-oxidation components. As an effective diesel engine oil additive, the product helps the blender maintain engine oil Base Number (TBN) consistently even as base oil TBN fluctuates between batches.
The finished oil produced using it maintains the oil base number (TBN) in the optimal range, provides excellent soot dispersion and high-temperature cleanliness, effectively protecting engine parts.

The biggest concern when compounding heavy diesel oils is the instability of the oil base number (TBN) in the finished product, caused by variations between base oil lots. If the ability of the oil to neutralize acids does not reach the required level, the finished product does not meet the quality standards, and end consumers experience corrosion and wear of engine parts, even leading to complaints.
The T3259 compound is built on a scientifically proven combination of several quality detergent additives, soot dispersant and high temperature antioxidants. As a high-quality diesel engine oil additive, it not only provides excellent soot dispersion, but also helps the customer optimize and stabilize the engine oil Base Number (TBN) during the compounding process. At the recommended dosage, the finished oil consistently achieves the required oil base number (TBN).
T3259 Series products are used primarily in the production of CI-4, CH-4 and CF-4 diesel engine oils using API I, II and III base oils.
