I've used commercial injector cleaner in the past with good results, but after reading the ingredients (they don't want you to know what's in them, but it's actually readily available on the hazard safety data sheets Smile ) I now use my own home-brew injector cleaner in both my diesels.

My formula is 85% paraffin or kerosene, 5% ATF, 5% IPA, 5% acetone (nail polish remover) or any aromatic hydrocarbon such as Naptha or Methyl Ether Ketone, etc.

The theory is the paraffin cleans the fuel lines, pumps, etc. the ATF offsets the lack of lubricity in the other ingredients, the IPA and acetone clean combustion deposits & varnish. Added bonus is that the IPA and acetone will also absorb any water in your fuel tank and burn it off nicely.

I fill up a 500ml Evian water bottle and squirt half of it in at every fill-up, although any brand of water container will do Smile

Total cost is about £8 for 5 litres. At 250ml per tank this lasts for 20 tankfuls. So 40p-per-shot. Compare that with the cost of commercial injector cleaner.

Even looks like redex in the bottle Smile

By way of evidence, just after purchase I had problems with my mondeo and the notorious 'flashing glowplug light' - and code P0251 Injection Pump Fuel Metering Control "A" Malfunction (Cam/Rotor/Injector). Went away and never came back after initially using BG244 injector cleaner then my home brew cleaner thereafter.

If I forget to use a squirt of injector cleaner for a few tanks in the mondeo, I get the fault back again Rolling Eyes

Works just as good in petrol motors too.

joztom je napisal/-a:Nafta ne more čistiti injektorjev, lahko pa jih podmaže in hitreje in lažje delujejo. Kamen topi alkohol ali kaka druga sorodna kislina, le-ta spremeni obliko vbrizganega snopa. Pri dodajanju kar tako je potrebno nekaj znanja, sicer lahko zariba ležaj HP pumpe, obloge pa se sicer očistijo. Torej ob čistilu se vedno doda ojačano mazanje goriva.
