Edited the OP.
How frequent are your regens? 24 engine hours? Or is the dpf filling up prior to that necessitating a regen? Any fuel additives?
I can’t say for certain but I’ve been doing several long road trips this interval. Like 5+ hours driving in a row and each time I could tell when it was passively regenerating by the fuel mileage and boost gauge. I run either archoil or hotshots EDT every fill up.
You won’t notice any changes during passive regen. Passive regen is when your egt’s are high enough to clear out the dpf from either towing or on a longer highway speed drive. Active regen occurs every 24 engine hours (in Ram with Cummins) or when the dpf soot level reaches 100% and is when you would notice changes in fuel economy (decrease). If you use any monitoring devices, you would notice an increase in egt’s during regen. Also, the only time you will notice any changes in your boost gauge are when you are on/off the throttle; this has nothing to do with regen.
Valvoline uses more magnesium than calcium in their formulation. Have to be sure that it doesn’t cause LSPI in our HD diesels with automatic transmissions. Im really not sure which is better. High magnesium or high calcium.
From what I remember, magnesium is a selective detergent while calcium is not. Magnesium isn’t as bad for DPFs though so it is added instead but does not react with all acids and combustion byproducts like calcium hydroxide does.
You need to find out where the fuel is coming from, regens or pump or injector(s). Ram had a major recall over the CP4 pump involving 2 years of production that the pump was used.
And how do you find that out? I see a "cleaning filter" msg once and awhile but assume I miss most as they stay on the dash display for only a few seconds.
Are you using the Archoil 6400D or the every tank 6500D ? The 6400D is recommended every 5k miles and it does a very thorough cleaning of everything fuel and exhaust related. I think there is a test for the fuel pump to see if there is any leakage there. Also if you determine that it is regen related be sure to check for leaks in the intake system ( losing boost ) around all of the boots and tubes from the turbo through the aftercooler and to the intake. Also check for exhaust leaks. Especially the Y-pipe if it has one.
