Injector Cleaning

I am getting ready to change my fuel filter and think I might try one of the injector cleaning methods. I use Stanadyne in the fuel during the winter months but no during the summer. I am just wondering what some of your suggestions are for cleaning the injectors. I have read the thread where you disconnect the fuel lines and run a concentrated mix of injector cleaner through. I have also heard of filling a new fuel filter with injector cleaner and starting it. I only have 35,000 miles on my 08 but want to keep the injectors clean.

do this method! there are a lot of people on here that have done this and seen great results. myself included. ill be doing this once a year from now on. the hardest part is drinking beer while watching the half gallon of diesel going down.
good luck!

I am just curious but is filling a new fuel filter with injector cleaner and installing it not a good idea? This would certainly be the easiest way.

no the GM fuel injector cleaner does not have enough lubricity in!! i replaced my fuel filter after running the injector cleaner. i still had 25% on it, but i like clean fuel.. and dont fill the new filter with fuel. just use the plunger to fill it. that way the fuel is properly filtered and not sending dirty fuel to the clean injectors.

Use a fuel additive year around. Keep adding some fuel additive @ each full fill up.

On a Cummins I would just fill the fuel filter with ATF. The detergent in the ATF worked well to clean injectors. This also gave some lube to the pump and would flush it out as well. I've not tried this on my Duramax. Anyone use this method on Duramax?

I run Lucas fuel treatment on every fill up and have not had any trouble with injectors.
