ExxonMobil has introduced a new lineup of Mobil Delvac 1 synthetic heavy-duty diesel engine oils, that includes three products that meet either API CK-4 or FA-4 specifications.

The new lineup includes:

• Mobil Delvac 1 ESP 5W-30, designed to deliver long and reliable service in the latest engine technologies.

• Mobil Delvac 1 Advanced Fuel Economy 5W-30, designed to meet the most stringent fuel saving objectives and for use in the latest low-emission engine technologies.

• Mobil Delvac 1 ESP 5W-40, offering smooth and reliable engine operation, including for off-highway equipment.

The company says that field performance and testing has demonstrated that the oils can help fleets minimize vehicle downtime and deliver increased fuel economy potential without reduced protection. The Mobil Delvac 1 5W-30 has shown through on-road testing that it can deliver high-temperature viscosity control, oxidation resistance and wear protection, even with oil drain intervals of up to 100,000 miles. This performance meets or exceeds requirements for even the most stringent manufacturer approvals, according to ExxonMobil.

Tests carried out by the Millbrook Group, a globally recognized independent vehicle test and validation provider, have shown that Mobil Delvac 1ESP 5W-30 oil helps improve fuel economy up to 2.6% in city driving conditions when compared against conventional mineral-based oils. These oils can also provide benefits for fleet owners focused on reducing waste. In lab testing, the Mobil Delvac 1 5W-30 oils showed a 37% improvement in oil consumption when compared to a comparable CJ-4 / MB 228.51 synthetic oil.

“Our new Mobil Delvac 1 oil technologies offer fleet managers a big opportunity to grow their business by taking advantage of only a small portion of their budget,” said Paul Cigala, commercial vehicle lubricants applications engineer at ExxonMobil. “Use of these oils translates into less money spent on fuel and maintenance and more money to invest in other areas of their business that will help drive growth.”
