What a coincidence, astraman, I have just opened up to ask the same question !
Just got back from National Tyres where they recommend an engine flush prior to a standard oil and filter change. I think there is some controversy about this in the trade and I think billryans has got it about right. Let's wait and see.
depending on the type of journeys u do depends on how the engine gets clogged up... i.e short journeys can destroy a engine in no time as the oil is designed to work efficantly at certain temperatures, i would only use the engine flush if the oil is solidifying in the engine as it can actually cause engine wear if used to often, as what ur doing is washing all the oil of the major internal engine components, which need to be covered by a layer of oil, using the correct oil and semi-synthetic or full-sythentic and changing the oil frequently... u should have no need for engine flush..
Ive always questioned the advantages of engine oil flush,ive never used it,ive always been happy with the conventional oil and filter change,but i have heard of garages that have accidentally left in the engine flush mistakenly thinking that the oil had been changed. Now that would wreck the engine! I believe that when engine oil flush is used ,the vehicle should only be revved to a fast idle for about ten minutes or so,if you dont use flush at least you cant mistakenly leave it in. Redline the engine once a week for a couple of moments,when warmed up,that will decoke it as well as any additives...not when stationary though!
