Mobilgard ADL Series oils (ADL 30 and ADL 40) are designed for high Brake Mean Effective Pressure (BMEP) medium- and high-speed diesel engines operating on distillate fuels. Their balanced formulation combats lacquer formation and deposits in severe service applications, and superior load-carrying properties minimise piston ring and liner wear while also suiting marine gearing applications. The series is intended for high-BMEP and severe duty engines where fuel and service conditions demand greater detergency/dispersancy and liner lacquer control than most diesel engine lubricants offer. It has demonstrated superior performance in engines from MAN Energy Solutions (Everllence) Augsburg, Caterpillar (3600 and C280 Series), Deutz and Wärtsilä, delivering dramatically reduced oil consumption, significantly reduced liner lacquering and extended periods between overhauls in extensive field testing, alongside excellent water separation and rust/corrosion resistance. Approvals and recommendations span Anglo Belgian Corporation dual-fuel and distillate engines, Caterpillar/MaK 4-stroke medium speed diesel engines, Everllence 28/33D engines, GE Transportation GE16V250, MTU Oil Category 2, Ortlinghaus-Werke ON 9.2.10, Wärtsilä 4-stroke medium speed and Vasa engines, and ZF TE-ML 04B, plus ACEA E2, Allison C-4, API CF/SF and MAN 270, depending on grade. Key benefits include superior wear protection, enhanced detergency/dispersancy, stay-in-grade shear stability, high TBN levels, and broad applicability as a single severe-service lubricant across shipboard engines.
