What is an engine detox? Normal servicing does not clean the inside of an engine. Deposits are a natural by-product of combustion and, without preventative maintenance, accumulate over time. Engine detox usually refers to the process of removing these engine deposits. BG Products develop and manufacture their own high quality chemistry and delivery systems to do this, safely and effectively. Other proprietary systems use different classes of chemistry, hydrogen, hot water or warm oil. Deposits attach themselves to many parts of the engine, including those critically important to the performance and economy - Fuel Injectors, Piston Rings and various sensors. If fuel injectors are dirty this will interfere with the efficiency and effectiveness of the fuel spray pattern. Deposits behind piston rings will restrict the ability of the rings to seal and therefore can cause a loss of compression. BG Products' research and development has developed the most effective treatments to safely remove these deposits. These include: Engine Performance Restoration flush: Highly regarded compression restoring flush from BG Products comprising quick and effective blend of cleaners that will soften, emulsify and dissolve hard to remove fuel gums that clog piston rings. Effective in 15-30 minutes. Safe for use in petrol, diesel and rotary engines. Diesel Air Intake Cleaning Service: Pressurised by workshop air, the BG Air Intake Cleaning System sends BG's specially formulated Diesel ISC Induction System Cleaner through the fresh air intake to liquefy and remove tough oil deposits and unburned fuel residues formed by the EGR and PCV/breather as the gases pass through the intake valves. Restores the vehicle to peak performance without the need for any engine strip-down.
