Eiffel Sahara Silver CF-4 series are diesel engine oils formulated with high quality base stocks and selected additives to ensure optimum performance and protection for diesel engines requiring an API CF-4 specification.  

Good oxidation & thermal stability reduces sludge build up and keeps the engine cleaner.
Optimum wear protection to extend engine efficiency and service life.
Improved fuel economy, due to high fluidity at low temperatures.
Reduced oil consumption at high operating engine temperatures.
Improved resistance to deposit formation keeps engine clean to give your vehicle maximum power under extreme operating conditions.
Optimum TBN reserves provide improved acid neutralization and corrosion protection, especially in old heavy duty diesel engines.


Suitable for diesel engines for both turbocharged and normally aspirated engines operating under severe service conditions in all seasons.
