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

  • ACEA E4, E7-12 

  • MB 228.5

  • MAN M3277, 3377


  • MTU TYPE 3 

  • Cummins CES 20077/78


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.
