About the Mack MP7
The MP7 is Mack’s mid-range heavy-duty diesel — same 10.8L displacement as the Volvo D11, sharing platform architecture under the Volvo Group umbrella. Common in regional haul, vocational, and lighter Class 8 applications. The shared engineering between Mack and Volvo means the oil specifications run in parallel: EOS-4.5 (Mack) and VDS-4.5 (Volvo) are functionally equivalent.
