Syntech 15W40 / 10W30 API  SL/CI-4

SYNTECH API CI-4 are premium quality engine oils series for turbocharged diesel engines running under severe conditions with extended drain intervals according to the manufacture’s recommendations. It is designed for highly rated diesel engines meeting Euro I, II, III, IV and Euro V emission requirements.

SYNTECH API CI-4 are formulated using highly refined mineral and synthetic base stocks and advanced additive technology of foreign production. These oils are providing effective control with respect to piston cleanliness and bore polishing. It further provides excellent wear control, soot handling and lubricant stability.

SYNTECH API CI-4 SAE 15W40 / 10W-30 viscosity grades are semi synthetic oils made from Hydrocracked base stocks providing cold start-up performance.


SYNTECH API CI-4 recommended for use in natural aspirated and turbocharged heavy-duty four-stroke engines operating under a variety of conditions where extended drain periods are required. It is suitable for most modern engines fitted with EGR and SCR NOx reduction systems.

SYNTECH API CI-4 series meets API CI-4 service category requirements and applicable for diesel engines where API CI-4, CH-4 and CG-4 oils are recommended.

SYNTECH  API CI-4 oils are recommended for highly rated diesel engines meeting

Euro III, IV, V emission requirements and running under severe conditions, e.g. extended oil drain intervals according to the manufacturer’s recommendations. It is suitable for engines without particulate filters, and for most EGR engines and most engines fitted with SCR NOx reduction systems.

SYNTECH  API CI-4 oils are also intended for use in high performance gasoline engines and car & light van direct-injection diesel engines as year-round lubricating oils.
