Zinc Replacement Additive

Part Number: HPZ212  |  Directions

Hy-PerLube Zinc Replacement Additive will provide maximum wear protection for cams and lifters in flat tappet cam design engines.

In an effort to extend the life of catalytic converters, the EPA and the OEM engine manufacturers have instructed the motor oil companies to reduce the levels of ZDDP (zinc dialkyldithiophosphate) in the oil. The ZDDP, when present in the exhaust gas, can coat the catalyst which results in higher emissions and shortens the service life of the catalytic converter. This reduced ZDDP approach works well to protect the catalytic converters but leaves many older and high performance engines without the proper EP (extreme pressure) wear protection they need to protect the cams, lifters and rocker arms. Virtually all non-roller cam designed engines are at risk for significant wear problems.

Hy-Per Lube Zinc Replacement Additive contains an exclusive Polymer Ester formula which, when added to any motor oil, including the new SM rated oils, will provide up to TWICE the EP wear protection as high content ZDDP motor oils and is also safe for use in all engines even those with catalytic converters.

Provides superior wear protection even
when added to oils containing reduced
ZDDP levels
Maintains a strong oil film at
high temperatures
Reduces cold start wear after long
periods of shut down

Environmentally safe, contains no heavy
metals and will not harm emission controls
or catalytic converters
Does not contain Zinc or Phosphorous
Compatible with all motor oils
including synthetic

Independent lab tests prove it protects better than zinc
