Description
Aztecs EMPROTEC Euro 10W-40 LA
The EMPROTEC EURO 10W-40 LA is a premium heavy-duty diesel engine oil engineered for optimum performance and protection in modern commercial and industrial diesel engines.
Built from superior quality synthetic base oils and enhanced with EMPROTEC's patented Adaptive Molecular Technology, this low-ash formulation delivers exceptional reliability, extended drain capability, and full compatibility with exhaust after-treatment systems.
Recommended Applications
- Ideal for truck, bus, coach, off-road and industrial diesel engines operating under extended drain intervals and heavy-load conditions
- Particularly suited for fleets requiring compatibility with after-treatment systems (DPF, EGR, SCR) thanks to its low-ash 'LA' formulation
- Also backward-compatible with older diesel platforms where 5W-30 synthetic low-ash oils are acceptable - giving fleet operators flexibility
- Recommended where OEM or specification requirements include: ACEA E6/E7/E9/E11, API CJ-4, MAN M3677/M3477, MB228.31/228.51, Volvo VDS-4.5/VDS-4, Deutz DQC IV-10 LA
Key Benefits
- Fuel-Efficient Formulation: The low viscosity 5W-30 grade improves cold-start flow and contributes to reduced fuel consumption in heavy-duty duty cycles
- After-Treatment System Friendly: The LA (Low Ask) version ensures compatibility with diesel particulate filters (DPF) and selective catalytic reduction (SCR) systems, preserving emission compliance
- Superior Protection Under High Stress: Excellent thermal and shear stability maintain film strength under high loads and temperatures, helping reduce wear and extend engine life
- Extended Drain Intervals: With high oxidative stability and low volatility, this oil supports longer service intervals, reducing downtime and service costs
- High Engine Cleanliness: Formulated to keep piston crowns, rings and injector nozzles clean, which supports efficient combustion and reduce emissions
