|In many locations, high sulfur distillate type fuels are common and this creates severe operating conditions. Fuel sulphur corrosion can promote excessive wear of cylinder liners, piston rings, valve guides, bearing, cams and tappets, etc. Gulf Dieselmotive are formulated to provide a high level of alkalinity, thus effectively nuetralizing the acids formed under these operating conditions. Gulf Dieselmotive 473, a fourth generation oil, has a TBN of 13 and can be used with fuels containing upto 1 % by wt. of sulfur. Excellent TBN retention properties enable this alkalinity to be maintained over extensive service intervals.|
|Gulf Dieselmotive oils may be used in a wide range of applications including drilling rigs, locomotives and stationary engines used for power generation, compressors, pumps, etc. These oils are also suitable for a wide range of marine applications, including tugboats and workboats. They provide superior deposit and wear control in EMD, General Electric, Bombardier, Caterpillar and other medium speed diesel engines. Gulf Dieselmotive 473 is also approved for Detroit Diesel 2 stroke diesel engines having valve distress problems.|
