With my previous 24V, 2nd Gen Dodge, I would periodically main line "Lubro-Molly" Diesel Purge to clean out the injectors, cabon etc. The stuff did wonders in restoring its power back and making it run again.

So my question is; has anyone mainlined Diesel Purge on the CR-3rd Gen engines. I'm not much up to speed yet on teh common rail and these expensive injector systems, but spring is around the corner and thinking of giving it a good clean out.

Thanks

Some people fill the filter bowl with their choice of injector cleaner when they change the filter... you could do that.

HMX-1

I do that with Power Service when I swap the fuel filter on my '06, and did it with my '03 when I still had it. Works like a charm.

I run Amsoil Diesel Concentrate every tank, seems to work good.

I want to clarify something. I used a BG product and poured it into the fuel tank when I filled up. I noticed a 5 mpg drop in what I usually get then the mileage came back up once the product went through the system. My question is, instead of putting the cleaner in the fuel tank, you're pouring the product directly in the fuel filter canister? If this is correct, what is the advantage of doing this over going through the fuel tank? Thanks

main lining it.

So should we follow the instructions on the bottle or back off the quanity being directly poured into the fuel filter canister? Also, which is the best fuel injector cleaner in your opinion?

i personally use lucas. with the amount of fuel being returned to the tank, not much goes into the injector so the majority of it get shoved back to the tank

But very very little actally gets to the injectors. Even on a stock truck the GPH of the LP is at least 35 GPH, and the truck only burns about 1GPH at a cold idle, and less than .5 GPH at a hot idle, so you won't hardly burn any additive.

Okay, so many different views on here. So what your saying adding the additive by main lining it won't make much difference vs. the fuel tank? Just trying to understand. Thanks

AH64ID

Correct. You will get an inital shot that is stronger than going into the tank, but not for very long. The vast majority of the additive will go directly back to the tank.

So if you tap the return fuel line and have it dump into the canister holding the fresh diesel purge, then you could go for sevral laps to clean it out?

I do this on the bigger non common rail Cummins.



Premium Plus Flush™ Carbon build-up in injectors is an enemy of engine performance. Carbon build-up contributes to rough idling, hard starting, excessive smoke, poor fuel economy, and premature wear.

Now you can help your customers win the carbon battle with Premium Plus™ Flush -- the safe and effective injector cleaner for their diesel engine.

By removing carbon deposits in injectors, Premium Plusª Flush restores lost engine performance and reduces operating costs. Best of all, Premium Plus™ Flush can be used with total peace of mind because it works without any harm to the engine or fuel system components.
Fast And Easy. Specially designed fittings connect the engine fuel suction hose to the fluid container. This enables the fuel pump to pull flush from the container while the engine is running. Unburned fluid is then returned to the container and recirculates again until all but a small residual is consumed. With the engine running just above idle (1000/1200 RPM), it takes 45 minutes to 1 hour to consume one gallon of Premium Plus™ Flush. Order Hose kit 3885739 containing all the necessary plumbing. Hose kit may be used from vehicle to vehicle.
Related Products. After cleaning the fuel system with Premium Plus™ Flush, keep it clean and protected against low quality fuels by specifying Premium Plus™ Lubricity Additive/Cleaner; it is the only fuel additive recommended by Cummins when low quality fuel is a concern. Used for preventative maintenance, Premium Plus™ Lubricity Additive/ Cleaner reduces wear and deposits -- prolonging the life of the fuel system.

• Win the carbon battle with Premium Plus™ Flush.
  
• Helps restore lost engine performance and reduces operating costs.
  
• Works without any harm to engine or fuel system components.
  
• Hose kit available containing all the necessary plumbing.

I would not fill the fuel filter bowl of a common rail with straight fuel injector cleaner.

Do not use this injector cleaner in electronic engines. This caustic cleaner was designed only for mechanical engines. It was developed for use in STC (step timing control) engines, however, it works great in small cam through BC IV engines and STC N-14s.

Sure seems like a lot of work.. why not just run a fuel additive on an regular basis.

I did it on my 2000 at least once or twice per year. It was relatively simple by popping off a couple of hose clamps and inserting in a 1/2 gallon container. I have a dual fuel system on this truck and same configuration. I have a pick up and return running to the same area on the auxillary tank. Since it appear it isn't going to burn up the injectors, I figure to give it a try when we get a warmer weekend. On the 2000 it would bring life back to the engine and fuel milage increased back to where it should have been in the 20's. With this 2005 if I can get it over 18 mpg again, that would make my day.
