I am a firm believer that this
forum should not be used as a selling tool. However, as supplier of the Flushing Oil Concentrate, I do need to correct some mis-information which could damage our reputation. I will also attempt to clarify the sludge/soot isue.
1. Our product is based on a purpose built, specific detergent in a lube oil carrier. It has no materials compatability problems with seals, O-rings, bearing materials or other. Importantly, it is not, as suggested, a solvent or degreaser, for some very good reasons...seal and O-ring damage could result; loss of oil viscosity could cause excessive wear; a crankcase explosion could occur.
2. Black filthy oil is NOT OK. Pre-combustion 4x4 diesels are high soot producers, compared to direct injection types. Black oil becomes a problem when it stains your hands. Clearly it can't keep the engine clean, can it? So sludge and piston ring fouling follow at some stage. It is a serious problem that can cause low (or excessive) oil pressure; lubrication starvation; the oil can become so thickened that it solidifies in the sump; chronic over-heating commonly results. (Few people realize that one of the oil's 5 duties is to provide sufficient cooling flow.)The sludge problem costs $millions a year, but it is avoidable.
3. Too clean? OLDER PETROL engines should not use the Flush, since in many of them, carbon pack out around worn rings can compensate for excessive wear. Many people identify with this. Diesels engines, however, specify a high detergent oil to control piston ring deposits. If fouling occurs compression drops as the rings progressively jam. Fortunately in most cases, wear is still within servicable limits. The symptoms are similar to a worn engine, and many are rebuilt at this stage.
4. Cause a rebuild? Many customers use our Flush as a last resort to postpone a rebuild, and while our success rate is above 90%, clearly if sludge is so severe that oil flow is inadequate, engine damage may have already resulted, before our product is used. We have engines running
well many years after postponing a rebuild. We have some that are rebuilt after a flush. And we have some that failed just before doing a flush. We are dealing with used (mainly problem) engines. Any suggestion of our Flush causing a rebuild is quite reckless.
I hope this has been useful background information on the subject, and satisfactorally corrects the mis-information in some of the threads.

Brd.
First, I think you should correctly identify yourself if you are the major supplier/ distributor of this product.
Second, engine flushing products are not new, they go back about as far as the original internal combustion engine.
Third, This product also claims to improve compression by removing cylinder glaze. This means an abrasive compound is incorporated in your product. (omo?)
Fourth, whether petrol or diesel, all engines require compression pressure to function correctly. Piston rings are designed to do two things only. a/ to maintain a piston/cylinder seal, and b/ control oil bypass to the combustion chamber to control excess oil consumption. To claim that diesels require "less fouled piston rings" is quite erroneous, after all, petrol engines develop far higher bmep's than their diesel counterparts.
Finally, for all the engines that failed "just before doing a flush"
Well it says it all.
Thanks for not trying to sell your product brd.
