No - the consensus is that if you put it straight in the tank, it gets diluted quickly and has next-to-no effect.Does it go right in the tank ??
No. Never run anything past your filter.No - the consensus is that if you put it straight in the tank, it gets diluted quickly and has next-to-no effect.
The method is to disconnect your fuel lines and run it straight out of a bottle instead, varrying the throttle for about 20 minutes or until it gets close to running out. The dump the rest in your filter to prime it, or the tank if you already primed the filter.
At work we put Seafoam in every diesel in the fleet. At home all my gassers, generators and mowers get Seafoam. I currently and for about the last 10 years or so run Diesel Kleen in my TDI's but would not hesitate to Seafoam them.Thanks John and Mongler!
Has anyone tried Seafoam?
When I did my 03' Jetta with 350K miles, the return fluid was just as clean as what was going in. Previous owner and myself only ever used pump diesel, no biodiesel. I did not notice any difference after running DP straight from the can into the IP.What do people see, coming through the return line, when they run a can of Diesel Purge through their IP? I helped someone do this yesterday, and the DP in the container quickly enough turned dark brown as it was cycled through the IP.
The person I helped only runs Biodiesel, the real stuff, no "renewable" diesel. Butt she bought the car with 200k, and so who knows what was run through before. Good points, that the return should be clear, and if it's not then good thing to be running the DP through.When I did my 03' Jetta with 350K miles, the return fluid was just as clean as what was going in.

I still need to give it a try on my Beetle, but I've got other issues lined up first, not to mention my broken wrist is still a problem (it's not healing up correctly).
This is pretty strong stuff and, in my experience, it did get close to plugging the fuel filter:Been around for over 68 yrs. & been in the auto , truck & heavy equipment repair for a few + decades .
Also owned many diesels , used commercial bio-diesel and went along with University studies & farmer coops to learn to make real bio-diesel .
Have used most of the long lived major brands of diesel / injection cleaners , without taking things apart & using magnification to check before & after using all of these products , what - if any difference was hardly noticeable .
So about 15+ yrs. ago , after buying my 1st commercial bio-diesel [ and knowing in advance to carry a spare fuel filter - when 1st using bio-diesel ] about 4-7 days & maybe 50-100 miles , I stop at my regular coffee shop , get back into the truck [ 1994 Dodge Ram with Cummins 5.9 ] it would not start .
So got out the spare fuel filter , installed the filter and truck started right back up and no issues .
Got rid of the truck do to rust - well actually the auto trans failed and I was not going to spend 3-4 thousand dollars for a rebuilt trans on a truck this rusted , had about 380,000 mile on truck .
From all of my experience , and what I learned about bio-diesel , it was proven to be the best cleaner --- no other cleaner ever plugged up the filter - bio-diesel cleans the entire fuel system - from fuel tank , lines , lift-pump , main pump & injectors .
This is a well known issue to be ready for when using bio-diesel in a fuel system that has run for some time on petro-diesel .
