К-481: for engine oil (API SL/CF-4)
Application
K-481 is an oil additive package for the main types of mobile engines, specially developed in order to provide highest technical parameters and optimal concentrations. K-481 may also be applied for manufacturing of the products, covering the whole range of viscosity grades under API including those from SL/CF-4 to SG/CD.
Dosage
K-481 additive package is developed to provide economical concentrations for production of oils from API SL/CF-4 to SG/CD levels.
