Would it not have a better impact on mpi petrols? like you say ruan the hdi is direct injection as is the newer golf I assume. but older cars the fuel is at least passing by the inlet valves?
The top of my pistons were caked in carbon when I went to do the HG, would this not help remove some of that crap?
