What is the absolute strongest diesel additive that can be used to break up carbon deposits? This is for a buddy, not me. Thanks!

 

I don't know if it's the strongest but i run DIPETANE according to the company it take's about 6000 miles to clean a diesel that has a lot of miles www.dipetaneUSA.com

 

I hear alot about a product called SEA FOAM....Pour it in the fuel filter housing....

 

ive used sea foam a couple of times seems pretty good ...

 

Bio diesel

 

I wanna some bio, but you can't get it here

 

Bio-diesel works gradually, we needed something stronger.
Thanks for the other recommendations, Ill refer them along.

 

Just about any additive will work gradually. If you are trying to go with something stronger, you take the risk of damaging the injectors. They require lots of lubication to prevent scoring, and most heavy abrasive cleaners strip the lubricity right out.

 

Great advice, thank you!

 

Carbon deposits in what? The injectors? Best thing is to take then out and have them professionally cleaned.

 

Biodiesel won't get rid of carbon inside the engine. I've seen first hand on the VW TDI's that I have to clean out the manifolds on. It simply coats the sooty deposits with a sort of plastic appearing stuff.

 

I agree Kwik, bio isn't the "clean all" everyone thinks. My buddy actually bought a tractor (Small diesel 3-cylinder) and it has low compression in one of the 3 cylinders, so he thought he would start with the excessive carbon theory first.....I didn't want to get into details since this IS a Ford site, but he just figured the "pros" out here would know what cleans up a diesel engine best....Thanks all

 

Oh I see.
This thread would be better off in "General Diesel" then. Lot's of different makes and models covered there.

 

Sea Foam does a heck of a job on the carbon in a 2 stroke outboard. I use it on all of mine. Especially the little idle-all-day trolling motors. You can pull a spark plug, look in there with a pen light and see the carbon. Run sea foam through it and it's gone. Haven't tried it on my truck though.
