Mack MP10 Engine Oil — Spec, Capacity & Change Interval
The Mack MP10 is Mack's largest-displacement diesel — 16.1L, rated 505–605 hp and 1,860–2,060 lb-ft — built for heavy haul, tanker, and high-GCW vocational work where the MP8 doesn't have enough torque. It requires Mack EOS-4.5 approved oil, and like every MP-series engine, FA-4 is not approved.
Last reviewed: July 2026 · Based on AMSOIL technical data sheets and Mack service documentation
Primary spec: The Mack MP10 requires Mack EOS-4.5 approved oil — a CK-4 based specification, functionally parallel to Volvo VDS-4.5. Run 15W-40 as the primary grade. Service fill with filter runs approximately 52 quarts (13 gal / 49 L). FA-4 is not approved for the MP10.

What Oil Does the Mack MP10 Take?
The Mack MP10 requires oil meeting Mack EOS-4.5, a CK-4 based specification that runs functionally parallel to Volvo VDS-4.5 under shared Volvo Group engineering. Use 15W-40 as the primary grade. FA-4 is not approved for this engine — EOS-4.5 is built strictly on the CK-4 platform, not FA-4's lower-HTHS chemistry.
The MP10 is Mack's equivalent to the Volvo D16 — both share the same 16.1L displacement and core Volvo Group platform architecture. This is Mack's largest engine, spec'd for operations where the MP8 doesn't have the torque headroom: heavy haul, tanker, and high-GCW vocational work. It is not a standard linehaul engine.
- → Required spec: Mack EOS-4.5 (CK-4 based)
- → Primary grade: 15W-40
- → Applications: heavy haul, tanker, high-GCW vocational — not standard linehaul
- → FA-4: not approved for the MP10
- → EOS-4.5 and VDS-4.5 are functionally parallel — same Volvo Group engineering
⚠ AMSOIL Synthetic Heavy Duty Diesel & Marine Motor Oil (AME) is not an option for the MP10. AME is formulated for engines without exhaust aftertreatment and is explicitly not for use with DPF or SCR systems. Every on-highway MP10 runs a full aftertreatment package, which rules AME out — use Heavy-Duty Synthetic (ADP) or Signature Series Max-Duty (DME) instead.
Mack MP10 Oil Capacity
The Mack MP10 takes approximately 52 quarts (13 gallons / 49 litres) at a service fill with filter — noticeably larger than the MP7 or MP8's sump, consistent with its role as Mack's largest-displacement engine. Confirm the exact total against your engine's service label before a change, since pan configuration can vary between highway and vocational MP10 builds.
| Fill Type | Quarts | Litres | Gallons | Notes |
|---|---|---|---|---|
| Service Fill with Filter | ~52 qt | ~49 L | ~13 gal | Standard oil change, most MP10 applications |
⚠ Always verify capacity with your engine's service label or Mack Uptime documentation. Heavy haul and tanker builds can run different pan configurations than standard vocational trucks. Overfilling causes oil foaming and aeration; underfilling reduces pressure margin under sustained max-torque pulls.
Mack MP10 Oil Change Interval
Mack does not publish one universal mileage figure for the MP10 — extended drains are supported with EOS-4.5 approved synthetic oil, but the actual interval depends heavily on duty cycle. Heavy haul and high-GCW work put more sustained load on the oil than standard linehaul duty, so confirm any interval beyond the OEM baseline with oil analysis rather than mileage alone.
(24–32K km)
(120,000 km)
⚠ Don't apply a linehaul interval to heavy-haul MP10 duty. Sustained high-GCW pulls run higher sump temperatures and more soot loading than standard highway duty. An interval that's safe on an MP8 linehaul truck can be too long for an MP10 pulling permit loads — pull a sample before assuming the same mileage applies.
What Is Mack EOS-4.5?
Mack EOS-4.5 is Mack's proprietary oil specification for the MP-series engines, built on the API CK-4 platform and shared functionally with Volvo VDS-4.5 under the Volvo Group's common engineering. On the MP10 specifically, that spec has to hold up under sustained high-torque, high-GCW loads rather than steady-state highway cruising.
Soot & EGR Compatibility
Keeps EGR-generated soot suspended independently so it doesn't agglomerate into larger, wear-causing particles as it recirculates through the oil.
Extended Drain Capability
EOS-4.5 approval requires the oil to hold up over Mack's factory-extended service intervals, not just the base CK-4 minimum.
Shear & Oxidation Stability Under Load
Resists viscosity breakdown under the sustained high-torque, high-GCW cycles typical of heavy haul and tanker MP10 duty.
Backward Compatibility
EOS-4.5 oils are formulated to also carry the earlier Mack EO-O approval, so a single product covers both spec callouts.
| Spec | Basis | Volvo Equivalent | Also Carried by AMSOIL ADP |
|---|---|---|---|
| Mack EOS-4.5 | API CK-4 | Volvo VDS-4.5 | Explicit approval on label |
| Cummins CES 20086 | API CK-4 | — | Yes — relevant for mixed Mack/Cummins fleets |
| Allison TES-295 | Transmission fluid spec, not engine oil | — | Referenced on ADP's OEM approval list |

Not every truck or budget calls for the same product. AMSOIL makes three diesel oil tiers, and all three carry Mack EOS-4.5 approval for the MP10.
| Product | Protection Level | Drain Interval | Best For |
|---|---|---|---|
| Signature Series Max-Duty 15W-40 (DME) · 5W-40 (DEO) | 6× wear protection — top-tier full synthetic | Up to 75,000 mi with oil analysis | Heavy-haul operators maximizing protection and uptime |
| Heavy-Duty Synthetic 15W-40 (ADP) · 5W-40 (ADO) | 4× wear protection — full synthetic, explicit EOS-4.5 label approval | OEM interval; extendable with oil analysis | Primary recommendation — synthetic protection at OEM interval |
| Commercial-Grade 15W-40 (SBDF) | 2× wear protection — synthetic blend | OEM interval only | Fleets upgrading from conventional oil |
Always match the oil to the MP10's viscosity requirement and confirm EOS-4.5 approval on the product label before purchase. Use oil analysis when extending intervals beyond OEM recommendations, especially in heavy-haul and high-GCW duty.
Why MP10 Operators Should Run Oil Analysis
The MP10's job is sustained high-torque pulling — heavy haul, tanker, and high-GCW work put more consistent load on the oil than standard linehaul duty. That accelerates soot loading and TBN depletion in ways mileage alone won't show. A basic sample checks the numbers that matter:
- → TBN: remaining acid-neutralizing reserve
- → Soot %: soot loading and viscosity risk from EGR recirculation
- → Wear metals: iron, copper, chromium, aluminum trending over time
- → Coolant contamination: early warning for cooler or gasket problems
Sustained max-torque pulls raise sump temperatures and accelerate oxidation faster than steady highway cruising. A rising viscosity trend on an MP10 UOA often shows up before a driver notices anything.
Iron ppm trending up against a flat aluminum reading typically points to liner or ring wear rather than turbo or bearing wear.
| KIT17 / KIT417 analysis kit | $25–$40 |
| Early liner/ring wear detection | Major repair avoided |
| Confirmed drain extension | Fewer oil changes |
| High-load soot/TBN trend | Rebuild risk reduced |
Mack MP10 Engine Oil — Common Questions
From owner-operators, fleet managers, and shop techs running the MP10 in heavy-haul and high-GCW applications.
What oil does the Mack MP10 take?
Mack EOS-4.5 approved oil. CK-4 15W-40. FA-4 not approved. AMSOIL ADP carries explicit EOS-4.5 approval on the product label.
What is the oil capacity of a Mack MP10?
Approximately 52 quarts (13 gallons / 49 litres) at a service fill with filter — larger than the MP7 or MP8's sump. Confirm the exact figure against your engine's service label.
Is the Mack MP10 the same as the Volvo D16?
Same displacement (16.1L), same Volvo Group architecture. The MP10 carries Mack branding and tuning; the D16 carries Volvo. Oil specs run in parallel — EOS-4.5 for Mack, VDS-4.5 for Volvo. An EOS-4.5 approved oil meets both requirements.
What applications use the MP10?
Heavy haul, tanker, and high-GCW applications where maximum torque is needed. Not a standard highway engine — used where the MP8 isn't enough. Think permit loads, heavy tanker routes, and specialty vocational work.
How often should you change oil in a Mack MP10?
Mack doesn't publish a single mileage figure for the MP10 — extended drains are supported with EOS-4.5 synthetic oil, but heavy-haul duty cycles vary enough that oil analysis, not mileage alone, should confirm any interval beyond the OEM baseline.
What AMSOIL oil is best for a Mack MP10?
AMSOIL Heavy-Duty Synthetic 15W-40 (ADP) — it carries explicit Mack EOS-4.5 approval on the label and is the primary recommendation. Signature Series Max-Duty 15W-40 (DME) is the step-up option for maximum protection and extended drains.
