Muscle Metal Treatment MT-10®


Typical applications:

  • Engines – gasoline, diesel, 2-cycle and natural gas
  • Transmissions – automatic and standard
  • Differentials
  • Gears
  • Gear couplings
  • Gear reducers
  • Bearings
  • Pumps
  • Electric motors
  • Hydraulic systems
  • Other lubrication systems requiring extra protection from extreme pressure, friction-related heat and high-wear conditions



  • Treats the metal – not the oil – by improving metal surface characteristics
  • Polishes, seals and protects metal surfaces of internal, moving parts
  • Reduces friction-related heat and wear
  • Extends equipment life through improved lubrication
  • Improves equipment performance and efficiency
  • Lowers system operating temperatures
  • Reduces energy costs and oil consumption
  • Improves fuel economy
  • Reduces maintenance and repair costs
  • Will not build up or change toleraances


  • Engines – Add 8 oz. of MT-10® to 4 to 6 quarts of oil in the crankcase every oil change.  For larger engine oil reserves, add 1.5 oz. of MT-10® per each quart of oil.
  • Automatic transmissions – Add 8 oz. of MT-10® to transmission through fluid tube.  For large transmissions, i.e. Allison, add 1.5 oz. of MT-10® per each quart of fluid.  NOTE:  Do not use MT-10® in ATV automatic CVT transmissions with EBS (Engine Braking System).
  • Standard transmissions & differentials – Add 1 oz. of MT-10® per each pound of gear lube. NOTE for differentials: Remove directed amount of lube first and replace with MT-10.  Do  not overfill.  Limited slip additive is still required.
  • Gear boxes – Add 2 oz. of MT-10® per each quart of oil.
  • Hydraulics – Add 1 oz. of MT-10® per each quart of fluid.
