Did you know?
There are two things that can clog up a DPF (Diesel Particulate Filter), one of them is “soot”, the other is “ash”. There is an important difference between the two.
Soot, also known as Particulate Matter (PM) is a form of incompletely combusted diesel and it contains mostly carbon. EnerBurn® is extremely effective in eliminating soot build-up by completing its combustion to CO2 (a harmless gas) and water. In plain language, EnerBurn eliminates soot by burning it out at temperatures normally achieved in the exhaust system.
What is “ash” and where does it come from?
Ash, on the other hand cannot be burned out. This is because “ash” consists of mineral elements that do not combust either with or without EnerBurn®.
There are a couple of known sources of these mineral elements.
One of them is fuel. Yes, that’s right, your diesel contains “ash”. Whether you fuel with #2 ULSD or a biodiesel blend the ash is always present as a low level impurity. These mineral impurities can slowly, over time build up in your DPF and cause restriction to flow of exhaust gases. This is why engine OEM’s recommend either cleaning or replacing the DPF every 200,000 miles or so.
The other source of ash is your engine lube oil. All petroleum based oils contain an “additive package”. The additive package formula may contain various levels of metallic or mineral components whose role is to enhance lubricity and reduce friction. Even a so-called “ashless” engine lube oil still contains ash, just lesser amounts.
How do I prevent my DPF from clogging with “ash”?
First and foremost, if your engine is consuming oil between oil changes, get it to a certified diesel mechanic as soon as possible so they can diagnose and fix the problem.
After that, my suggestion would be to find out what engine lube oil is recommended for your engine type. You should also take into account the type of driving you do and the geographic region you cover that includes considerations such as extreme inclines and ambient temperatures.
I suspect that my DPF is clogged with “ash”, what now?
There is a good chance you can restore your DPF by having it cleaned at a shop with the proper cleaning equipment. This DPF cleaning equipment is casually referred to as “Blow and Bake” or “Shake and Bake”. The following YouTube video shows what you are looking for:
