EP4020 Applications: 


EP4020 is a multifunctional additive designed for Engines and Drivetrains.  It is the Gear Up and Engine Up combined for compatibility with all oils for protection.


Directions For Engines: 


Add EP4020 at 5% of Engines crankcase quantity 2000 km before oil change. Change filter and oil and add another 5%. After first 2 treatments, you only need to add to your oil changes every 15000 km. Trucks every 250 hrs. 
Add EP4020 to your 2 stroke oil at 5% than mix as directed to your petrol. 


Directions for Drivetrain and Hydraulics: 


Add EP4020 at 5% to Drivetrain with a good clean quality oil. If oil is black it is contaminated and needs changing. 
In large hydraulic systems >400 L, you require 20 L EP4020. Notes: The cleaning action of EP4020 may lead to filter blockage after initial treatment - replace filters after 20 hrs of operation. Flush and service automatic transmissions prior to adding EP4020. Not compatible with brake fluid. 

Available sizes: 1L, 5L, 20L, 205L

Data Sheet

I would recommend Smith Lubricants in any machine as the fuel savings more than cover the cost of treatment.
