The engine from the 14-ton M-151 Military Utility Tactical Truck MUTT was modified to reduce the amount of blowby that reaches the engine oil in an effort to extend the oils useful life. Both dynamometer and road evaluations of the engine were conducted. Although the modified engine failed to complete the 32,180 kilometer 20,000 mile road evaluation, the unmodified control vehicle, which operated without oil or filter changes, demonstrated that operation without oil drains is almost feasible using high quality MIL-L-2104CMIL-L46152 qualified lubricants.
