Alto Al Humo

Wynn's Alto Al Humo is specially formulated to stop exhaust smoke due to oil burning. Wynn's Alto Al Humo is specially designed for oil burning cars and trucks and has a new improved super thick formula, which is more effective in sealing the gaps between worn internal moving engine parts that cause exhaust smoke due to oil burning.

Wynn's Alto Al Humo is formulated to improve compression for better performance and to quieten most engine noise by providing extra lubrication protection. Wynn's Alto Al Humo contains Wynn's Friction Proofing to reduce friction and wear, and to prolong engine life.


Wynn's Alto Al Humo is specially formulated to provide the following advantages:
  • Reduced Oil Consumption
    The chemical polymers and viscosity index improvers combine to increase the resultant oil viscosity and its ability to withstand a broad range of operating temperatures. This improves sealing between the piston ring and cylinder wall as well as taking up slight wear between valves and guides, the most common oil loss areas. Due to the feature of high temperature viscosity improvement, leakage loss around main oil seals is reduced also.
  • Extended Engine Life
    This is achieved as a result of overcoming severe abrasion and metal-to-metal contact. The Wynn's Friction Proofing package actually forms a molecular bond to the surface of the metal particularly when heat, velocity and rubbing friction occurs.
  • Decresed Exhaust Smoke
    By controlling oil consumption, visible exhaust gases are reduced.
  • Decreased Engine Noises
    Wynn's Alto Al Humo provides a cushion between worn parts, helping to reduce engine noises and friction.
  • Reduced Wear
    Wynn's Alto Al Humo helps reduce engine wear resulting from direct metal-to-metal contact under extreme operating conditions such as sustained high speed and trailer haulage.
  • Improved Compression
    Wynn's Alto Al Humo improves the oil viscosity at high temperatures, thereby improving the ring sealing actions and engine compression.
  • Improved Oil Stability
    Wynn's Alto Al Humo retards the oxidation and breakdown of motor oil at high operating temperatures.

Key Benefits

Wynn's Alto Al Humo is a complex formulation of chemical polymers, viscosity index improvers, anti-oxidants, corrosion-inhibitors, anti-foamants and detergent/dispersants. These compounds combine to produce the following additional benefits:

  • Maintans Oil Pressure at High Temperatures
  • Improves Performance in Worn Engines
  • Improves Fuel Combustion
  • Improves Lubrication
  • Reduces Sludge and Varnish Formation
  • Inhibits Corrosion
  • Acid Neutralisation
  • Cleaner Engine Components
