BRITON BTP 304 – BTP 404

BRITON BTP 304 – BTP 404 is a range of trunk piston engine oils developed for use in medium speed diesel engines burning residual fuels. BRITON BTP 304 – BTP 404 combines an exclusive formulation of latest additive technologies and a highly refined base oil to provide a substantial safety margin to cope with the higher stress levels even with the latest and future designs of diesel engines.

Product Description

APPLICATIONS

  • Highly rated medium speed diesel engines used in marine and stationary power generation applications, burning heavy fuel oil with various qualities and Sulphur contents.
  • Particularly suitable for low or very low oil consumption engines operating with a poor quality residual fuel.
  • Bearings and stern-tubes.
  • Reduction gear lubrication.

PROPERTIES

  • Reduced build-up heavy deposits in the engine leading to a reduction in maintenance costs.
  • Excellent resistance to the negative effects of contamination with residual fuel.
  • Excellent thermal resistance and high temperature oxidation resistance.
  • Excellent control of viscosity increase leading to reduced top-ups.
  • Very good water resistance to maintain the engine performance and to remove the water rapidly after water ingress.
  • Very good wear protection and very good oil film strength at extreme pressures.
