if I could (not touched for over 250k miles!) so had a search for an effective fuel additive to see if this would clean things sufficiently. Normal car shop additives did nothing but then I found 'Archoil AR6400-D MAX Engine, Turbo, DPF & CAT Cleaner'. Given the spec it seemed it could cure things so put some in, went to Wales and back in April (600 miles) and problem looks as though solved. The additive possibly has cleaned things sufficiently to get over the problem so I will use this periodically to continue the cleaning process, hopefully! Good luck!
Hi Bjorn, I am a new member here, after 25 years I am about to own a cruiser again so I joined this forum. I would agree with Shayne especially about the water contamination. The product "Bigone" is describing (Archoil AR6400-D MAX Engine, Turbo, DPF & CAT Cleaner') has a water desperant in it. Any water that makes it's way to the fuel lift pump will come into contact with a fine nylon or wire mesh. This mesh is probably fine enough to stop water once it has become oily with fuel. If water was present using this above product would have caused the water to disperse and thereby unblock the mesh and therefore allow proper fuel flow the High pressure pump. It is a good idea to add a fuel treatment on a regular basis but I would caution you to not use it with every fill up unless you think you are using dodgy fuel. Drum fuel is a shocker for water as they are rarely store correctly. Most modern premium diesel fuels already have additives mixed in.
