Drive Longer with Pure Mack Engine Oil

Regular oil changes are probably the most important preventive maintenance (PM) check you can perform on your Mack® truck. That’s because dirty oil can clog your engine, leading to reduced fuel efficiency, premature wear and unplanned downtime.

But it’s not uncommon for fleets to let oil change intervals slide a little past OEM recommendations. Sometimes it’s a conscious business decision to help stretch the budget, while other times, logistical challenges come into play. Either way, delaying a scheduled oil change can put your truck at risk for an unexpected breakdown.

Typical maintenance standards call for oil and filter changes every 25,000 to 45,000 miles, depending on application and duty cycle. But now it’s possible to lengthen those intervals by up to 10,000 miles with new Mack EOS-4.5 Premium Plus Engine Oil.

Designed to extend maintenance intervals for Mack MP7, MP8 and MP 10 engines, new Mack EOS-4.5 oil delivers enhanced protection against oil oxidation and oil aeration control. And that can help reduce the formation of sludge and deposits, and guard against inefficient heat transfer.

New Mack EOS-4.5 also offers:

• A lower-viscosity 10W-30 formulation that improves fuel economy, even under high loads and high ambient temperatures
• Extended drain interval recommendations of 30,000 miles for severe duty, 40,000 miles for heavy duty and 55,000 miles for normal duty
• Protection above and beyond the new American Petroleum Institute (API) CK-4 specification
• Compatibility with older, previous emissions-level engines

But longer service intervals don’t just mean more time between oil changes. They also translate to fewer oil changes overall. In fact, the extended protection of Mack EOS-4.5 means you can skip between four and 16 oil drains over the life of your vehicle. And that can save hundreds of dollars per year for each truck in your fleet. In fact, new Mack EOS-4.5 oil is so effective, we’ve made it our new factory fill oil.

So be sure to ask about new Mack EOS-4.5 Premium Plus Engine Oil during your next PM check. And don’t forget – it’s also available now through the SELECT Part Store™. Sign up today to take advantage of 24/7 online ordering, quick delivery and exclusive discounts.
