Increased by extending the oil change intervalPlus income
Without affecting the wear protection of the components, extending the oil change or maintenance intervals is the best way to help you directly increase your profits. TranSynd is an effective powerhouse when extended drain intervals are reached. TranSynd has excellent oxidation resistance and shear stability during use, reducing the possibility of sludge formation, paint film build-up and viscosity loss. The extended oil change interval award directly saves your product and filter costs, and indirectly saves equipment downtime, labor, oil storage and waste oil disposal costs.
