Having the oil changed during the week at National Tyres, Very Good price for change using Castrol Edge. Thing I want to know, is it worth having the "Engine Flush" done? Only £8, any real benefit as my oil is changed every 3k - 4k.
From their blurb!
Engine flush (£8.00)
Engine Flush is specifically formulated to combat modern motoring issues caused by the adverse affect of extended oil drain periods.
During the long interval between oil changes, crankcase acids are produced. If left within the system when the oil is changed, these acids immediately go to work breaking down the new oil leading to the creation of lacquers and varnishes which are deposited on the oil system components such as Hydraulic Valve Lifters, Variable Valve Timing Systems and Piston Rings. These components work within very tight tolerances and any sticking due to the deposits in the oil system results in inefficient operation of the system and poor driveability.
The engine flush National Tyres and Autocare provides cleans sludge, dirt, varnish and other contaminants from the engine, whilst cleaning the Valves, Hydraulic Lifters and other oil system components. By having an engine flush on your vehicle prior to an oil and filter change it helps to improve the engine performance and keeps new oil cleaner for longer.
