Petadd VM-34(C) is a pellet-form, olefin copolymer (OCP). It is an economical choice when looking to increase viscosity in mineral oil based automotive crankcase lubricants.


  • Use as an additive to increase and maintain viscosity in crankcase lubricants.
  • The recommended treat rate is 5 to 10%, (depending on base oil used, and the required viscosity).
  • Dissolve completely in base oil (under high agitation at ~110°C for 8 hours).


  • Easy to handle
  • Easy and quick to use (fast dissolving pellet)
  • Highly stable (polymer product)
