    Mobil Delvac Range FAQs

    It’s true that Mobil Delvac can help to extend the life of your commercial vehicle engine.

    However, the actual life of an engine prior to overhaul depends on many variables from oil-drain intervals and maintenance practices to your driving habits and the load carried.

    But using Mobil Delvac engine oils will certainly help keep the engine-life odds in your favour.

    Both in the engine and driveline, it can.

    So you have two things to consider: A multigrade product tends to provide better fuel economy than a monograde (e.g., a 5W-40 is better than a 40 grade) and lower viscosity products tend to provide better fuel economy than higher viscosity products (e.g., a 5W-30 provides better fuel economy than both a 10W-30 and a 15W-40).

    As equipment ages, deposits and wear accumulate, resulting in a decrease in equipment efficiency. Mobil Delvac™ lubricants are able to protect the engine against deposit formation and wear, and resist soot-induced and oxidative viscosity thickening, allowing the equipment to maintain fuel economy throughout its life, making Mobil Delvac a great choice for diesel engine oil.

    Many truck engines idle for very prolonged periods during cold winter temperature conditions to allow for warm-up and to keep the cab warm.

    Prolonged idling will reduce engine life and also waste fuel. Engines operate cooler while idling, and during long idle periods in winter's cold temperatures, moisture in the intake air can condense in the engine crankcase and produce corrosive sulphuric acid, which can attack soft bearing alloys.

    Long idling also contributes to increased soot and combustion contaminants, which will shorten the engine oil's life prematurely and can lead to excessive piston deposits, sludge formation and detrimental viscosity effects.
