Mack Anthem Maintenance Guide: What Owners Need to Know
Mack Anthem maintenance follows a **25,000-mile PM interval** for major services, with oil changes every **15,000 miles** using 15W-40 diesel oil. The Anthem requires **40 quarts** of oil and uses a **Mack 57MD316P oil filter**. Most shops charge **$350-$450** for a standard oil change and **$1,200-$2,500** for a complete PM service depending on what needs replacement.
Mack Anthem Oil Change Intervals and Specifications
The **MP8 engine** in your Mack Anthem holds **40 quarts** of 15W-40 diesel engine oil. Mack recommends oil changes every **15,000 miles** under normal conditions, but if you're running heavy loads or in extreme temperatures, drop that to **12,000 miles**.
Use the **Mack 57MD316P oil filter** - don't substitute with aftermarket filters that look similar. The bypass valve pressure is calibrated specifically for the MP8 engine. We see oil pressure problems when owners use the wrong filter.
Oil capacity: 40 quarts with filter change
Filter part number: Mack 57MD316P
Oil grade: 15W-40 API CK-4 or CJ-4
What's Included in Mack Anthem 25,000 Mile Service?
Every **25,000 miles**, your Anthem needs a complete PM service. This isn't just an oil change - it's a comprehensive inspection that catches problems before they leave you stranded.
The service includes oil and filter change, fuel filter replacement, air filter inspection, coolant system check, brake adjustment, and a **72-point DOT inspection**. We also check the brake system for proper adjustment and air leaks.
**Fuel filters** get replaced every PM. The Anthem uses two filters - a primary and secondary. The primary filter part number is **Mack 25014231** and the secondary is **Mack 25014232**. Don't skip the fuel filters - we've seen $8,000 injector failures from dirty fuel.
If your Anthem is due for PM service or showing any warning lights, call Skyliner Truck Center at (570) 655-2805. We'll get you in and out fast so you're not losing money sitting in the shop.
Common Mack Anthem Problems We See in Our Shop
**EGR" target="_blank" rel="noopener">EGR valve failures** are the biggest problem we see on Anthems with **150,000+ miles**. The valve gets clogged with soot and throws **SPN 1436** or **SPN 1437** fault codes. Replacement costs **$1,200-$1,800** including labor.
**DEF system problems** show up around **200,000 miles**. The DEF pump fails and you'll see **SPN 5394** codes. Don't ignore these - the truck will derate to **5 mph** if the system stays faulted. Pump replacement runs **$800-$1,200**.
**Air compressor failures** happen between **300,000-400,000 miles**. You'll notice longer air buildup times and oil in the air tanks. A rebuilt compressor costs **$1,500-$2,200** installed.
Mack Anthem Transmission and Drivetrain Maintenance
Most Anthems come with the **Mack mDRIVE automated transmission**. The transmission fluid should be changed every **500,000 miles** or **5 years**, whichever comes first. Use only **Mack Transmission Fluid** - part number **Mack 20098630**.
The **differential** needs service every **100,000 miles**. Rear differentials hold **3.5 gallons** of 80W-90 gear oil. Check for leaks at every PM - a leaking pinion seal will destroy the differential if it runs dry.
**U-joints** typically last **200,000-300,000 miles** depending on your routes. If you feel vibration at highway speeds or hear clicking during turns, get them checked. A failed u-joint can destroy the transmission or differential.
Mack Anthem Brake System Maintenance
**Brake adjustments** should happen every **25,000 miles** during PM service. The Anthem uses **S-cam brakes** with automatic slack adjusters. If the adjusters aren't working properly, you'll get brake fade and excessive lining wear.
**Brake linings** typically last **100,000-150,000 miles** on the steer axle and **80,000-120,000 miles** on the drive axles. Replace when lining thickness drops below **1/4 inch**. A complete brake job on an Anthem costs **$2,500-$4,000** depending on which axles need work.
Check DOT brake requirements before your annual inspection. Out-of-adjustment brakes are the most common DOT violation we see.
