GREENSBORO, N.C. — Mack Trucks has released extended engine oil drain intervals for customers using its newly formulated genuine Mack Engine Oil EOS-4.5.
Depending on the application, oil drain intervals have been extended by up to 15,000 miles compared with previous formulations, helping reduce customer maintenance costs.
Introduced as the factory fill in Mack’s 2017 engines, genuine Mack Engine Oil EOS-4.5 also extends drain intervals for all 2011 and newer Mack engines.
“There is a misconception that Mack Engine Oil EOS-4.5 is simply a rebranded version of the other engine oils on the shelf, and nothing could be further from the truth,” said Scott Barraclough, Mack technology product manager. “Mack Engine Oil EOS-4.5 is a proprietary formula that is tested and approved with Mack equipment, which allows us to extend drain intervals.”
With Mack Engine Oil EOS-4.5, drain intervals have been extended to 60,000, 50,000 and 40,000 miles for long-haul, regional-haul and heavy-haul applications respectively, Barraclough said.
During the life of a Mack truck, these extensions allow customers to skip between four and 16 oil drains, helping save hundreds of dollars per year per truck, he said.
Mack Engine Oil EOS-4.5 is available in 10W30 and 15W40 weights and meets Mack’s stringent EOS-4.5 engine oil standard, which offers protection above and beyond the new American Petroleum Institute (API) CK-4 specification by requiring enhanced performance for oil oxidation and oil aeration control. It is also formulated with a lower viscosity, helping improve fuel efficiency, even under high loads and high ambient temperatures.
Mack Engine Oil EOS-4.5 can be used anywhere API CK-4 oils are recommended and is also fully backward compatible with all API CJ-4 applications.
