Hercules LD 10W-40

Synthetic Technology Long Drain Diesel Engine Oil

BULWARK HERCULES oils are synthetic blend, long drain Super High-Performance Diesel engine oils (SHPD) designed to meet latest ACEA requirements and more challenging OEM specifications for Euro 4 & 5 compliant diesel vehicle equipped with EGR, SCR & NOx reduction systems. Not recommended for engines with diesel particulate filters (DPF).


BULWARK HERCULES LD 10W-40 oil is manufactured using optimized combination of synthetic and mineral base oil with premium additives to provide proven & reliable long drain interval and all year-round performance. Recommended for use in naturally aspirated and turbo-charged high speed 4-stroke diesel engines deployed in off-highway and on-highway applications including the mining & construction industry, where ACEA E4, E7 & API CI-4 oils are specified.   

Performance Level

  • API CI-4/SL

Key benefits

  • Lower maintenance costs from minimized piston crown deposits and prevents damage to bore.


  • SAE 10W-40 multi-grade viscosity ensures improved oil circulation and reduced friction at start-up and maximum lubricity at higher operating temperatures.


  • Excellent oxidation stability & BN reserves ensure negligible oil degradation and improves oil service life in turn providing Longer drain intervals.
  • Lower oil consumption due to high shear stable VI improvers and low volatile synthetic base fluids
