Home : PRODUCTS : Diesel Engine Oils : ULTRA 1 SAE 40 API: CC/SC


  • Ultra 1 HD 40 are low dispersant oils and allow the suspended matter to drop harmlessly into sump.
  • Ultra 1 HD 40 also have enhanced anti-foam properties ensuring optimized performance in diesel engines.
  • High viscosity prevents oil from leaking.
  • Minimizes engine noise.
  • Provides outstanding anti-wear/anti-scuffing protection for engines operating under mild service condition.
  • Excellent option for vintage car lubricant and air cooled application where a mono-grade viscosity is preferred.
  • Reduce internal friction while maintaining their strong lubricating film protection even under the most demanding torque and extreme temperature conditions.
