Ametech Metal-Tec10™ is an advanced technology, anti-friction lubricant additive, consisting of a blend of the highest quality petrochemical products. It is a maximum duty, metal conditioning formula especially recommended for use in lubrication systems where there is a special concern for extra protection due to extreme pressure, friction-related heat and high-wear conditions.

Metal-Tec10 flattens metal surfaces to increase lubrication and reduce drag (friction). There are many other oil additives on the market that act in a similar way but, unlike the others, Metal-Tec10 contains no chlorinated solvents or phosphate compounds and is PH neutral, protecting the metal surfaces against acid erosion which occurs when short-chain chlorinated hydrocarbons mix with water droplets and moisture to form hydrochloric acid.

Metal-Tec10 contains no PTFE, silicone, graphite, moly or solid lubricants and is neither acidic nor alkaline, just pure petrochemical halide blending. Metal-Tec10’s formula allows it to blend well with all types of petroleum and most synthetic lubricants (but not vegetable oils or esters), enhancing the performance of both.

Metal-Tec10 has been formulated to increase the efficiency and performance of your automobile, truck or commercial vehicle. But in order to obtain the full benefit of the product, it requires dedicated interest on your part to follow product directions and take proper care of your vehicle. Oil changes, oil filters, gas filters, good grades of fuel, proper lube jobs, tune ups and qualified auto technicians performing maintenance and repairs all pay dividends toward the annual expense and the life of your vehicle.

Ametech Metal-Tec10™ Metal Treatment is recommended for these automotive applications:

  • Engines. Nothing protects better at start-up!
  • Transmissions (Automatic & Standard)
  • Power Steering/Rack Assembly Units
  • Differentials
  • Recommended for gasoline & diesel engines



  • Smooths, seals & protects metal surfaces of bearings, pistons, cam, crankshaft, lifters & all other internal, moving metal parts
  • Protects engine against friction-related heat & wear
  • Free governors and eliminates governor hang-ups
  • Reduces operating temperatures
  • Increases horsepower
  • Extends the life of lubricated engine parts
  • Reduces oil consumption
  • Recommended for petrol & diesel engines.


One of the biggest enemies of a transmission is heat. The amount of heat present in the system will normally dictate the lifetime of that transmission. When Ametech Metal-Tec10 is added, heat is significantly reduced. Metal-Tec10 addresses the extreme-pressure (EP) areas, such as planetary and worm gear systems, along with bushings, bearings and shafts.

VALVE BODY OPERATION: In many cases presented by professional transmission builders, Metal-Tec10 has freed the valve body and maximized performance with no recurrence of sticking or intermittent hang-ups.

GOVERNORS: As most transmission builders are aware, there are certain governor systems that have unique tendencies to hang up for no apparent reason. Two reasons these hang-ups occur are contaminants and microscopic spiking of the metal due to electrolytic corrosion of the metal. Ametech Metal-Tec10 will displace contaminants and smooth and seal metal surfaces, removing electrolytic spikes and preventing their formation.


  • Reduces heat
  • Frees valve bodies for maximum performance
  • Free governors and eliminates governor hang-ups
  • Keeps oil passageways, orifices and ball checks clean and fully operational
  • Extends the service life of the transmission
  • Eliminate premature failure and costly call-backs
  • Reduces wear & metal particle fallout & debris
  • Removes varnish buildup
  • Eliminates lock-up chatter in the torque converter
  • Insures proper shift
  • Does not affect seals & gaskets
  • No negative affect on sprag or clutch friction*
  • Recommended for automatic & standard transmissions
  • Contains no PTFE, graphite, silicone or moly.

* Although Metal Tec10 reduces friction, it has no negative affect on the sprag or clutch friction necessary for the operation of the transmission. As confirmed by Raymark in a letter of October 1986 in testing their SAE clutch pack: "The results of our test indicate no change in the friction levels, thus we do not expect the addition of your additive to have a negative effect on our friction products."

IMPORTANT: Metal-Tec10 should not be used in CVT gearboxes. CVT (Constant Variable Transmission) oil or fluid improves the friction/grip between rubber/metallic belts and alloy/composite pulleys, whereas Metal-Tec10 reduces friction between metal-on-metal components, spool valves & spindles lubricated by ATF (automatic transmission fluid) in automatic transmissions. As these requirements are opposed, neither ATF nor Metal-Tec10 should be used in CVT rubber/metal belt transmissions.



  • Protects against friction-related heat & wear
  • Smooths, seals & protects metal surfaces
  • Reconditions rack piston & cylinders
  • Helps return smooth & easy operation to the unit*

*If you are experiencing difficulty with the unit, we recommend the unit be thoroughly flushed prior to the addition of Metal-Tec10.



  • Treats the metal surfaces of the gears
  • Protects against friction-related heat & wear
  • Optimizes performance for more power
  • Extends the life of lubricated differential parts.

NOTE: Limited slip additive is still required with the use of Metal-Tec10.



  • Gears
  • Bearings
  • Engines
  • Heavy equipment
  • Gear couplings
  • Pumps
  • Transmissions
  • Hydraulic systems
  • Electric motors
  • Gear reducers
  • Heavy machinery
  • Lubrication systems requiring extra protection from extreme pressure, friction-related heat & high-wear conditions.


Carried to the moving metal parts by the fluid to which it is added, Ametech Metal-Tec10™ creates a boundary film which smoothes and seals metal surfaces to reduce friction and friction-related heat. This results in less wear and smoother operation of the mechanism with no danger of build up or changes in tolerances. The end result is improved operation of the system.

Ametech Metal-Tec10 improves the overall tribological properties of the metal surfaces. Film strength is a function of surface roughness and viscosity. The smoother the surface, the higher the film strength, while viscosity can be lower to improve fluid flow conditions. The diagram below on the left illustrates how asperities - the high points and low points in surface metal - affect the flow of oil between two metal surfaces. The diagram below on the right shows the difference after application of Metal-Tec10 to the oil.The metal surfaces are smoothed, increasing the boundary film strength of the oil and promoting a stronger flow of oil between the two surfaces.

Ametech Metal-Tec10 treated surfaces will increase fluid film strength, reducing friction, heat, wear and energy consumption. This returns efficiency and previously wasted energy back to the system for increased power. This process, combined with the physical surface improvement of the metals, steps up oil flow, reduces metal film strength, improves the shear strength of the base lubricant, and results in an overall reduction in friction and friction-related wear.


"Wear testing has been completed on your six samples using ASTM method D2783-88, Measurement of Extreme-Pressure Properties of Lubricating Fluids (Four-Ball Method). The test method is used to differentiate between lubricating fluids having low, medium, and high levels of extreme-pressure properties. Three steel balls are clamped together and covered with the lubricant to be evaluated. A fourth steel ball is pressed into the cavity formed by the clamped balls for three point contact. The temperature is brought to 18.33 to 35°C, with a rotating speed of 1760±40 rpm, then a series of tests of 10 second duration are made at increasing loads until welding occurs.

Values are obtained for weld point (the load in kilograms at which the rotating balls welds to the three stationary balls, indicating the extreme pressure level of the lubricants-force has been exceeded) and load wear index (load-carrying property of a lubricant – the average of the sum of corrected loads determined for ten applied loads immediately preceding the weld point) for each sample identification. Additional sheets attached show the individual load results for each material.

Test Results
Sample Load Wear Index Weld Point Kg
A. T-Plus Teflon 43.7 200
B. Supreme Plus 59.9 250
C. Slick 50 42.5 200
D. STP Engine Treatment 58.5 315
E. QMI Engine Treatment 49.0 250
F. MT-10 Engine Treatment 246.4 >800

Repeatability of the test is such that the difference between successive results obtained by the same operator with the same apparatus under constant operation conditions on identical test material would, in the long run,  in the normal and correct operation of the test method, exceed the following value only in one case in twenty: repeatability = 17% of the mean value. The Muscle product (MT-10 Engine Treatment) did not weld at the highest load the instrument was capable of running, so the load wear index for it is an approximation. It has extreme pressure levels much higher than any of the other samples.” (December 22, 1993)

Reviewer: Tony Bellamy from cheltenham   5 Stars

2 words needed: brilliant and amazing. Used this for over eight years now and in so many applications. Now I just take the view that if there is either oil or grease needed, then it would be very limited without MT10. This gives me insurance and assurance that whatever will not wear out, produce less friction less heat and last for as long as needed. This has saved many thousands in repairs, replacement and maintenance over the years. Many receive advice, only the wise profit from it. Remarkable stuff.
