Diesel purge is good for a better cleaning of carbon on injectors,pistons,valves,prechamber,ect..
Other products reduce the need for a purge.Purge is really needed when burning veggie,or wmo/watf.

So, you do admit that Diesel Purge has the ability to clean the fuel system. That would seem to contradict your earlier claim that the product is "junk."

Removing a layer of slime and removing carbon are two very different things.

Bio fuel is also corrosive to rubber.

People who have actually used Diesel Purge probably have a different opinion. They have seen how dark the return fuel becomes and they have experienced how much better their engines run.

x2, with the LM DP product, the fuel coming back from the return line is almost BLACK! LM DP really works. But you have to use it properly i.e. run it straight from a separate container. It cannot be mixed into your tank.

Hi
After changing out my leaking return lines on my 1985 300Td -t, the returning Diesel Purge came back perfectly clear - not black.

Leads me to think that all that black stuff people keep seeing in thier returning Diesel Purge - is really from deteriorated return lines.

For what its worth,
Joseph

FWIW:

I have run Power Service Diesel Kleen for 5k miles. It just recently made the idle noticeably smoother.

When I bought the car 5k miles ago, it had a stuck open thermostat which I'm sure contributed to carbon deposits.

I had the intention of running LM but could not find it locally so I never did.

Clarify please. I thought the return line returned the fuel that was in excess of what the injector could deliver. Isn't it only cleaning the fuel system on the non combustion side of the injector?

Take the injectors off the engine and get them physically cleaned.

Alright, smahtypants, can you tell me how exactly they clean them when they're out? Mechanically or chemically?

Neither. Part of a proper injector rebuild is to disassemble the injector bodies and ultra-sonic clean them.

If you use a wire brush or any other mechanical cleaning method, well, congrats, you've just destroyed your injector nozzles.

I was disappointed that my diesel purge did not become dirty at all

I guess that means I have a clean engine, though. I do use Howes Meaner Cleaner in each tank.
However, the DP did still make a bit of a difference, despite not returning black.
