Despite the constant change of oil and filter over the time recommended by
the manufacturer, the car engine becomes old and its performance gets weak
due to the corrosion that results from continuous friction in spite of the
use of the best types of engine oils, so we recommend using one of
O2PROFORMANCE products (EZI engine treament product) which has gone under
Laboratory experiments that have indicated it reduces friction to more
than 71% and increases engine life by 38%, as it increases engine
horsepower by 4.8% and reduces gasoline consumption by 3.7%.
