Sinopec Tulux 15W-40 Diesel Engine Oil is a premium quality, heavy duty diesel engine oil formulated with fully synthetic base oils and an additive package containing advanced dispersants and detergents. It is suitable for use in high speed, four-stroke cycle diesel engines fitted with exhaust gas aftertreatment systems designed to meet all exhaust emissions standards.


Sinopec Tulux Diesel Engine oil is suitable for use in:

Heavy duty diesel engines fitted with modern exhaust gas aftertreatment systems, e.g. exhaust gas recirculation (EGR),diesel particulate filters (DPF) or selective catalytic reduction (SCR).

Heavy duty diesel engines without exhaust gas aftertreatment systems.

High speed, four-stroke cycle diesel engines adopting other new technologies and meeting Euro IV (ADR 80/02) and Euro V (ADR 80/03) emissions standards.

Heavy duty diesel engines requiring an API CJ-4 quality oil.

Gasoline engines requiring an API SM quality oil.

  • Excellent dispersant/detergent properties protect the oil from soot-related viscosity increase, prevent the formation of sludge and piston deposits, and reduce valve-train and soot-related wear, keeping the engine clean and reducing energy loss due to frictional wear.

  • Outstanding shear stability protects the oil from viscosity loss due to shear in highly-rated diesel engines, keeping the oil in grade and extending oil life, and ensuring optimum oil film thickness on moving engine parts.

  • High-TBN formulation, together with anti-corrosion properties, neutralises acidic combustion products and protects engine bearings from corrosion and wear also enables longer oil-drain intervals and so reduces maintenance costs.

Very low oil evaporation loss reduces oil consumption and exhaust emissions.

High viscosity index base oil and effective antioxidant system protect the engine at high temperatures and prolong engine service life.

Fully compatible with common elastomers used in engine seals, so reduces oil leakage.

Meets a wide range of industry and OEM specifications, so useful in mixed-fleet operation where it can reduce inventory costs.
