I don't have any issues with my engine, no excessive smoke even under hard acceleration but a friend recommended Millers Diesel Power Ecomax and said that this will help clean injectors. Is this a load of hype or do these additives really work?
I usually fill up at non supermarket fuel stations anyway (Shell, BP), but would an additive be a waste with non supermarket fuels?
TIA
