probably just bg44k lol
so do they have a specific name for this engine treatment? i might give mine a call and see if the guys start scratching their heads!
This is the stuff they use
It is indeed very good and does clean the insides of the fuel system out. But dont pay the price Ford charge, you can get it from any car parts place for about a fiver
I had this done on my diesel and an engine flush, did not notice or feel anything so I won't do it again. Firm believer in a good quality oil and decent fuel.
indeed it is the stuff they use but they also use the engine flush and flush the engine at the same time still impressive stuff
