Q1: How will new Mobil Delvac oils compare with previous CJ-4 versions? Cigala: In extensive testing, our new Mobil Delvac CK-4 and FA-4 engine oils have outperformed previous CJ-4 oils against the API requirements in many key areas, including: • 80 percent improvement in high temperature viscosity control, helping to protect engines from severe operating conditions;* • 50 percent improvement in oxidation resistance, helping to enhance engine life by reducing deposit formation of sludge and varnish;* and • 20 percent improvement in wear protection, which can help enhance engine durability and keep engines running more efficiently for longer periods.** These outstanding results can be credited to the extensive testing and research we have done to support the development of these oils. To date, we have conducted more than 30 million miles of on-road testing with leading fleets and equipment manufacturers. While both CK-4 and FA-4 oils provide these improvements, the FA-4 oils, designed for engines model year 2017 and newer, will provide additional potential for fuel economy benefits. Ultimately, these Mobil Delvac™ oils will provide balanced performance between the improvements in wear protection and fuel economy. Q2: What steps should fleets take as they switch to the new CK-4 and/or FA-4 oils? Cigala: It's important for fleets to know that PC-11 will NOT change many of the best practices that help drive their success. And, the only change that most fleets will see is how advanced CK-4 or FA-4 oils can deliver better performance than a previous CJ-4 counterpart. As they transition to CK-4 or FA-4 oils, fleets should work closely with their lubricant supplier to ensure they choose the right lubricant based on specific engines and common operating conditions. Q3: Will the new oils produce different oil analysis results? And how much data is needed before a fleet tries to optimize drain intervals? Cigala: There will be some slight variations in oil analysis results between CJ-4 and CK-4/FA-4 oils, such as additive levels. But, the biggest testing results fleets will see is various improvements in oxidation stability and enhanced viscosity control. Before considering oil drain optimization programs, we'd suggest that fleets take advantage of our Mobil Serv Lubricant Analysis and have at least two or three oil drains using the OEM recommended intervals. This will help set an appropriate baseline to evaluate engine performance with the new oils and determine if an optimized oil drain interval program can be started.

Mobil Delvac TM 1300 Super diesel engine oil has the ability to extend oil drain intervals by up to 50 percent beyond OEM recommendations. This means trucks can stay on the road and be productive for longer periods of time.* *Results may vary based on vehicle/engine condition, driving and environmental conditions.
