Mobil Delvac Legend 1330 is an SAE 30 monograde diesel engine oil from the Mobil Delvac Legend 1300 Series, formulated from advanced-technology base oils and a balanced additive system for intercooled, turbo-charged engines operating under severe on- and off-highway conditions. It is used where a monograde lubricant is recommended. ExxonMobil recommends the series for naturally aspirated and turbo-charged diesel-powered equipment in light, medium and heavy-duty trucking, as well as construction, mining, quarrying and agriculture. Key benefits include excellent protection against oil thickening, high-temperature deposits and sludge build-up for prolonged engine life and reduced wear, along with an extended TBN reserve that controls acid formation when using higher-sulphur fuels and protects against ring sticking. Mobil Delvac Legend 1330 is recommended for applications requiring API CF, API SF and Allison C-4. Typical properties include a viscosity index of 99, sulfated ash of 1.1 mass%, TBN of 10 mgKOH/g and a pour point of -27°C.
