   Right now I used the search button but I have a number of queries about this...
   
   A) How much is needed to flush engine when changing oil? Just a bit or pour the whole bottle in?
   
   B) I take it I use standard engine flush to do the gearbox also?
   
   C) How much do I use for the gearbox?
   
   and D) what brand shoud I use? Does it matter or do they all do the same thing?
   
   Thanks!

   Why?
   
   I use the forte range of flushes on every oil change.
   My dad owns a garage and uses it on most cars which come in for a service.

   Is that anything to do with leaks etc.? As I read something about engines leaking after being flushed.

   I would drain the oil, use some cheap oil and run it for a short while then drain that and replace with good quality oil.

    Very mixed opinions. I saw a thread on cliosport and they were all praising it.
    
    Here is a different story though.

    The reason flush is bad for your engine is because it takes all the lubrication of internal parts.

    it will not do ur engine any good it washes all of the goodness out of ur engine and the film that putting good oil in ur engine coats all the parts will be washed away
    
    if u wanna put engine flush in up to u fella ,if it was that good it would say in all service books use engine flush and it dosent

    Alot of engine flushes break down the oil so it becomes thinner at a lower temperature and breaked down hardened oil that block channels and holes! While its doing this there is still oil running through the engine so it will still be protected on idle, just not at any speed or load! The oil is also easier to drain than just warm oil, so there is less left in the engine to contaminate the new oil!
    
    A large amount of engine builders and mechanic use products like these everyday! I really doubt professionals would use these products if they where detrimental to engines! Also doubt the market for products like these would be as big!
    
    My two pence!
    
    Not wanting a arguement just saying what i think!

    i wouldnt bother tbh. i have used it on a previous car and yes it did feel better but the things you read about removing all build up of old oil from around the block could in theory unblock any small cracks that may be inside the engine and potentially make them worse quicker. dont hold me to this, this is just what i have read.
