This. Holiday season coming soon so I'm daily checking to see any mention about sales and when parts fall off, free flowing parts rise back on.

 

Why fuel additive do you use? You said you currently see 350 miles between regens, what were you getting before? I tried Ford's PM-22 but the results were eh eh.

 

I was going about 150 miles between regens. I have been using PM-22 also for years also. Didn’t seem to notice any difference and did not like how the bottles leaked. I just recently tried Optilube XPD. Read I shouldn’t use it due to alcohol or something but my truck seems to like it. Even idles quieter in the cold. I was most impressed watching the soot level not increasing as fast.

 

Good to hear. I'm thinking about trying the Optilube Summer+ or XPD as i've read great reviews on them.

 

Archoil guys it works

 

To the OP - you might try a product known as a FBC (fuel borne catalyst). These are said to improve the burn efficiency and alter the soot content of the exhaust coming out of the cylinder. One brand I have heard good things about is "Better Diesel" FBC. A friend of mine uses it in his Dmax and his regens went way down in cycle duty.

At this point, it might be worth a try. And, no I don't own them, own stock in them, work for them, or such. Just trying to help someone out here.



PS - This reminds me of why I got a 6.2L ...

 

I really only drive city, rarely get on the freeway, lots of short trips, I have always timed the end of the day to make sure to get the truck up to full temp for a few minutes at the end of the day though. I was lucky to go more than 100 miles between regens, I have always used either fords pm-22 or stanadyne performance formula, I ordered some of the better diesel FBC and my first 0% to regen with the FBC got me over 200 miles, 2nd regen went 250, and it looks like this one is gonna be about 250 as well, this stuff really works, only complaint is they charge a lot for shipping, and I think my mpg’s may have gone down a little, although I don’t track mpg’s closely. Also, my truck always goes to 0% every time, unless I turn off the truck. Example, I dropped my kid at soccer, during a regen, it was at about 80% on its way down, I put it in park and decided to let it idle to let the exhaust cool, since regens add a lot of heat, and it just kept dropping, all the way to 0% the exhaust coming out was hot enough to cook the hair off my hand for about 15 minutes. Didn’t idle up, or anything, which I though when the truck went to park the regen was supposed to cancel, but I don’t think it did for me. Sorry, kind of rambling, but if you have short regen cycles, try the FBC stuff, it works for me.

 

This thread has me wanting to pay attention to how many miles I get between regens. I do know that it is not that frequent. My last regen went down to 30%, I've driven approx. 300mi. and its currently showing 80%.

 

When I frst got my truck I was going about 250 miles between regens. I started using Opti-Lube Summer+ and was able to get at or close to the 500 mi mark everytime. 6 months ago I aded Better Diesel FBC. After the break in period I was able to consistently hit the 500 mi mark and hardly ever hit 100% soot level. Usually by the time I hit 500 mi I am at 75-85% Soot level. This is all while empty.

 

My question is if they are really going through a regen every 500 or less then how the hell do they ever get clogged up. If you ask me sounds a bit fishy really. Just like everything else nowadays. My Dodges would tell you when it would regen and it was very rare if you actually worked the truck and ran it.

 

There was enough heat and you let the motor run so it continued to cook, just in a passive regen way.

Note you should never just shut the truck down during a known regen. Simply let it idle a few minutes to cool things down and get the unburnt fuel out of the cylinders.

 

That’s why a chime or something should let you know when it’s doing a regen.

 

Yeah I didn’t think shutting it off during regen would be good, you would think they Would have something to say, “your exhaust is extremely hot right now, allow engine to idle for a minute to cool down before shutting off”

 

It's important to have a way to monitor EGTs because of the above comments. It's also important to let the truck idle after driving hard or towing / hauling heavy. I usually line to wait until EGT11 & EGT12 are in the low to mid 300 F range before shutting off the truck but maybe I'm being a little cautious.

 

22k miles and 3 years later, I’ve never “felt” a regen. And frankly, don’t want to by the sounds of it!
