Thread: Diesel injector cleaner additive ?

Diesel additives have a place depending on what you think you need to achieve... I use Wynns EDT as a bug preventer and helps to keep the injectors from building up varnish as I mostly use Gull diesel - this doesn't have the brand specific additive that the other mainstream fuels have so the EDT takes the place of the additive dose that is present in the other brand fuel. I had one diesel vehicle start running like a complete bag of snot, rough running, hard starting, consumption on the inbuilt display went up by 2.5L/100km and I was thinking it was about to fully shit itself. Realised I hadn't dosed the thing for a few months as it was the wife's car so took it down, filled it up and gave it a double dose. 15Km later it was back to running normally and 7L/100km instead of 9.5...

So additives can do a lot for you in the right conditions but they aren't god bottles. They won't ressurect an engine that's obviously beyond it!
