Protec Engine Flush DETOX4®

Base price with tax


Why use engine flush?

Every time any engine is started, carbon and other organic contamination is left behind in the motor oil. An engine is flushed because an oil change only removes the old oil and refills the motor with new oil.

An oil change process does almost nothing to remove the majority of contamination from the motor.

Over time, these contaminants will build into deposits that can reduce performance, can cause a motor to burn oil, can lower compression, and can lower gas mileage.

Protec Engine Flush DETOX4® will break contamination down to a third of a micron and after use the engine will be restored, cleaned, protected, and running at optimal efficiency.


Does it work with my vehicle’s oil type?

Safe to use in regular motor oil and full synthetic motor oil.

It is recommended to use engine flush before switching to synthetic from regular motor oil.

Each bottle contains 375ml (12.68oz) and can treat a motor with up to 6 quarts of oil.

How does engine flush work

The solvents, detergents, and atomized cleaners in DETOX4® fully dissolve deposits down to a third of a micron. This means you never have to drop the oil pan, clean an oil screen, or worry about chunks of contamination breaking free and floating around in your motor.

Chemicals in the formula restore the existing, dirty oil’s viscosity to 96% to help protect the motor during the flush.

Other chemicals also protect the internal components, gaskets, o-rings, rubber hoses and aluminum. It uses an atomization chemical process to effectively break down gum, varnishes, residues and other carbon deposits in any motor.

It also uses an "emulsification" agent to bond with any water in the oil or motor. The chemicals bond with these unwanted contaminates after breaking them down to a third of a micron. These tiny particles are then held in suspension inside the dirty oil.

All of the contaminates & emulsified water are then removed from the vehicle during a regular oil change procedure.

  • DETOX4® is safe to use in any vehicle because it fully dissolves contamination and protects the motor by boosting the old oil’s viscosity up to 96%.
  • It will not corrode or dissolve aluminum, rubber hoses or critical motor components.
