DEF system maintenance

Does it work? I don't know. I believe the product is good. I don't have DEF system issues on a LZO duramax or a 21' Cummins diesel. Maybe this product is why I never have an issue. This should help prevent crystals building up from DEF. Preventative maintenance is important and this is it's intended use. I will continue to use it.

Used after the initial DEF product, this one seems to have things working well

I used their initial product in DEF tank since I had been geting P20EE codes regularly. I could see crystalization around pour tube, cap, etc. I put it in, then I got the dreaded Poor DEF Quality message and P20EE code again. Then it went away. A few miles later, back again. Then after a few days. maybe 75-80 miles, no more codes.Took a long trip of 650 miles, plus local driving, code and DEF message have never appeared again. Seems to do the trick. I also add in this Rislone maintenance DEF fluid product. Seems to all be working as intended.

Beware! Don’t use

Do not use if you have a 4th or 5th gen RAM diesel. Causes level sensor errors and the dreaded “Service DEF see Dealer” message. Took three warranty replacements of the DEF pump/tank to realize this stuff was causing the failures! Bought the six pack and can’t use and it’s been 6 months so I’m stuck with the rest.

continuous DEF flow

I have a 2017 Volvo VN daycab. DEF was not being used up by truck. Had no light on dash. Filter soot level was increasing and within a couple of days it was almost full.Went the cheapest, fastest way to find a solution. So I changed my DEF tank filter and simply added this solution to DEF tank, really easy. Seemed to have broken up whatever was clogging the system and now my DEF is being used up and back to regular usage.
