Mobil Delvac 1 full synthetic 5W-40 diesel engine . Shipped in a case of 4 one gallon containers. Simply the finest diesel engine oil, providing a full 40 weight oil thickness protection and a superior additive package capable of providing oil change intervals of up to 100,000 miles for over the road trucks! You will be amazed with the instantaneous starting with Delvac 1 and its overall performance! If your diesel is EGR valve equipped and/or exhaust particulate filtered, Delvac 1 ESP is your answer for long lasting, trouble free operation! Mineral based diesel oils create an almost resin like substance in as little as 25,000 miles, causing the EGR valve to stick. Delvac 1's 100% "real" synthetic base stock (as opposed to Group III wannabee synthetic base stocks) stands up to the grueling temps, providing trouble free EGR performance! Delvac 1 ESP meets/exceeds API service levels CJ-4, CI-4Plus, CI-4, CH-4, CF-4, SL and SJ.
