Liqui Moly DPF cleaner

[Greg Roles]

Yeah that'a a little ambitious, though it will help your normal regens happen quicker, and likely make the time between them greater as passive will also be better.

My vote is the $100 Liquimoly flush every hundred thou - if it works!!

i know, it all started with the EGR problem.I drove around for a few months with the fault light on. i was told it would likely be clogging up the DPF so I started using.Tough habit to break you know.Anyway had that EGR sorted as I think we have discussed back in time.Love a good deal so I kept on putting it in...The liquidmoly sounds like the go.Most informed people I encounter rate their products highly.I am going to give the inlet manifold cleaner a shot soon, possibly today.
What do you all think about this product? I like the idea of a quick cheap clean but not sure about all that gunk going into the cylinders at once?May possibly have an adverse effect on rings , valves and DPF etc?

Every fill!?
so much for economy!

[Greg Roles]

Do it, better to flush it through than have it build up on the valves, and yes, you will dump more oil into the DPF and that will leave ash, but it's going to end up in there eventually. My inlet valves at 50 thou, even with two in series Provent 200's had buildup, especially the passenger side cylinder, which had a nice 2-3mm lump of buildup. Remember this is the most restrictive part of your engine, and you want good port flows!

Do the latest tractors have any emission control equipment I wonder?.

A word of warning should you use the intake cleaner, do be careful as the tube attachment tends to leak where it fits into the press button at the top of the can.I discovered as I was spaying into the intake it dripped onto my grill...It eats plastic! Not so pretty...Seems to do a good cleaning job though.

I thought it was a safe product for plastic induction manifolds.

What is being discussed here is a direct to DPF fluid. Then you have fuel additives, then you have intake cleaners. People are confusing them.
This 2 stage DPF cleaner is designed to go directly into the metal DPF can, not through the fuel, like a petrol additive ( which would not get your intake anyway - direct injection ). The only intake cleaners are the seafoam types, and the diesel specific one is fine for plastic.

[Ryeman]

Greg, isn't this a retail product, and as such, how would the average Joe get it directly to the can?.

[Greg Roles]

Yep, ideally you want the super expensive wand and air setup, but so too just the fluids injected under pressure would work - via the top O2 sensor port, not a simple task, but easier than cutting it open and washing it out!

Any mechanic could handle it for you I reckon.

[stevan]

Yes it was the intake cleaner that ate my grill! Not DPF cleaner...

So how does it not eat plastic induction manifolds?.

[Greg Roles]

Inlets are nylon based, bumpers are plastic based.

Ah
its all plastic to me ))
