simple to use with each oil change, follow instructions and use when engine warm. As a final suggestion pour some clean cheap oil into the engine and let it run out before replacing the sump plug as that will force out some more remaining old cruddy oil.

there is an big write up about this this cleaner but sorry to say it is no diffident to WYNN'S ENGINE FLUSH, to which is cheaper. to which i use before , it Flush out the old and some of the brown bit in the engine oil and the carbons , yes recommend it as for value think really for what it is should be cheaper then what it selling for . mean it over priced . i have not see it all come back to silver meaning metal , to what some write up all most say, but can say it help to drain the oil better . so it up to you what you buy its okay for what it is

Bought a 16 year old petrol Land Rover with a suspect service history. This product worked a treat cleaning the oil system out.

Seems to have done the job, but who can say unless you have cameras inside the engine before and after. Engine seems quieter and smoother. I would probably use again.

you cant see what it does, but when I drained the oil it seemed very black, so I guess that must have been gunk that it has loosened up from inside the engine. hopefully?
