HiTEC® 12208 is a high-performance additive package from Afton Chemical designed for formulating high-quality heavy-duty diesel engine oils, particularly for applications requiring API CF-4, CF, and CD level performance. It is optimized for use in older diesel engines, off-road machinery, and stationary engines operating under moderate to severe conditions.
Formulated primarily for use with Group I base oils, HiTEC® 12208 delivers robust wear protection, good piston cleanliness, and dependable oxidation resistance. It is a cost-effective solution for regions where mid-tier diesel oil performance is sufficient or preferred, especially in agricultural, construction, or mining fleets where API CF-4 level oils remain in active use.
