Seafoams main purpose is to clean the fuel system and injectors. It will supposedly clean combustion chambers. I used it in my IDI and It sure felt like I gained some power. I poured the entire contents in my fuel filter and then restarted the truck. It complained for about 10 minutes and if I goosed the throttle, the smoke was FOUL smelling. The directions on the can say to fill your filter or add it to the tank. My next filter change I will do it again in the filter. About 2 weeks ago we did the same thing on my sons '98 Dodge 5.9 12V and he said it is running stronger..

I replaced the fuel filter element, filled the bowl with Seafoam, pour the rest in the tank, and she never missed a lick. I am sure she runs smoother with mileage improvement.

I've run seafoam in all of my vehicles. My dad has used it for over 30 years when ever he has some slack buildup, to dissolve varnish in older engines, as a fuel injector cleaner, to decarb top ends and he really likes it because it is safe on diesels, 2 and 4 strokes. It is one of the very few universal cleaners that will not hurt anything. They started as a marine engine cleaner and that is where he picked it up.

Another product that I use in my diesel and enjoyed was the BG 44K Power Enhancer. I bought it locally upon recommendation from a friend. It worked just as designed and never had a problem with it.

Edit: Most auto parts dealers have them I.E. Autozone, O'reilly, Pepboys, etc. Trying getting a shop price on the large container. You will find uses for it everywhere and it's a lot cheaper per ounce that way.

I don't know about diesel but I use Seafoam regularly when I am dealing with appliances that will not be used for a long time like the lawn mower in the winter or the snow blower in summer. Other than that, people have made claims that it cleans this, that or the other. None of it documented so I don't believe them. To me cleaning fuel parts like this is simply like sweeping the floor of a room in the dark. You never know if you got it all or whether you missed something or the floor is cracked. If you think there is an injector problem, take the things out and have them tested so you KNOW what it is doing at the time instead of guessing. Sure, they can go bad right after you reinstall them but I think the odds are better with an actual inspection.

At 200K Blackstone sugest that I extend my oil change interval because my oil was not breaking down. Now I change the oil 6K are longer and use Seafoam every other oil change. 500 miles before the oil change add a can to the oil and watch the difference in the color of the oil. WOW 263K and no prolbems.
