    You certainly cleared up some questions I had about DEF. Most especially about price point v/s real world quality. I was at Lowes a few weeks ago and saw some Platinum Peak for close to $20! Thank you for taking the time to research this subject. This is information I can use.

    Just subscribed and I wish I had found your site sooner...DEF...I learned the hard way...THERE ARE DIFFERENCES!! I own a 2016 RAM 6.7 2500 with 70k miles, live in MT and when the weather allows I pull a 10k GVWR fifth wheel trailer and behind the trailer I pull an ATV. Earlier this year we were on our way to the Big Horn mtns in WY to camp in our favorite spot (~8,600 feet). Prior to leaving, I topped off the DEF tank at a local truck stop with the bulk DEF. We arrived in good shape and the truck basically sat for a week as we primarily used the ATV. After breaking camp and hooking up we began our trip to the next camping spot (also in the Big Horns) and the check engine light came on! We idled down, called our dealer and were advised to take the truck to a nearby dealer which we did. After diagnosis, they told us the DEF in our tank was the cause of the problem. They drained what was remaining and replaced it with Peak Blue DEF and we haven't looked back since. Apparently ours was not the only RAM 6.7 they had serviced for the very same thing - poor quality bulk DEF. Made a believer of us and now we ONLY use prepackaged Peak Blue DEF.

    I work within a NH3 plant in Oklahoma - we make NH3 from natural gas - our sister plant takes that NH3 & Demineralized water to either make 32.5 or 50%. We ship it out in rail car or trucks. There are at least 50 -100 trucks ship per day - we have changed nothing in our process to make different kinds. It’s either pure 32.5 or 50%. We ship 5-10 rail cars every week. Yes when stored at the house keep in a cool / dry place.

      Plus at Wally World, there have been instances of people buying the DEF, putting in their truck then refilling with water. They take the jug back and get their $$ back. It can be done without actually breaking the seal. Then you but it, put water in your DEF and bingo, the dreaded "See your dealer. DEF system" comes up on the EVIC. Not to mention its about 2 times more than at the pump.

    There's always talk about deleting. To each their own. However, in California, we can't get away with it. The communists insist that we have our trucks smogged even more often that gasoline trucks. I am told it's because so many owners apply aftermarket computer mapping and also alter the exhaust.
    I'm happy with the way the truck runs as it came out of the box. "If it smells like cologne, leave it alone!"

    well marion, you went deep into this video.
    thanks for that class profesor.
    the only question I still have is about the platinum.
    what is your personal opinion and choice?
    do you believe it really reduces long term issues?
    and, how long term are we taking about?
    interesting enough:
    if you compare peak standard vs platinum, is only $3-5 more in most of the cases.
    but the price of NAPA (that you mentioned is blend by the same Old World Industries, LLC) vs platinum is double.
    whats your personal take or guess on it?

I best friend is the parts manger and my dealer goes through a lot of def fluid just from selling to fleets. I’m sure every dealer in USA is can differ from that.

    I'm like you Marion, I like to use it from the boxes or jugs. Seems less likely to be contaminated.
    I feel like that if you use a known brand, the difference is likely negligible.

      I ve had several folks ask me that. They are the original OEM. Here a link, not sure if these are the same ones I have but they look like it. www.moparmidwestparts.com/oem-parts/mopar-battery-shield-5033395ac?c=Zz1lbGVjdHJpY2FsJnM9YmF0dGVyeS1iYXR0ZXJ5LXRyYXktYW5kLWNhYmxlcyZsPTE5Jm49QXNzZW1ibGllcyBQYWdlJmE9cmFtJm89MjUwMCZ5PTIwMTQmdD1sYXJhbWllJmU9Ni03bC1sNi1kaWVzZWw%3D

      Thanks Marion, much appreciated. I couldn’t find them because I didn’t search with the term “shields”. The material they used on my 2016 is disintegrating as I type!

    • @tomgarifo6698
      @tomgarifo6698 4 года назад

      Just a follow up. Your battery shields came directly from the factory. I found them pictured on the moparwholesaleparts website which apparently is “third party run”.So I ordered them. They sent me the same felty crap material ones that I already have. I was told they don’t sell them anymore and that Chrysler controls the pictures on the website. Oh well I tried.

    In the semi trucks that I drive, we buy from the highest volume dealers{truck stops} . That's the freshest Def that is available and way cheaper per gallon.

    As DEF expires or goes bad due to age or heat will it show up when reading a DEF refractometer and if so will it be above or below 32.5? Thanks!

      Yes it should and I would think it would read high if water has evaporated but don't really know.

    What ever the magic 3rd ingredient is in the Peak Platinum made no difference. Actually seemed lower in longevity then normal Peak. In my non-expert opinion the Platinum is not worth it and all the others you mentioned do the job.

    manufacturers should be forced to print the manufacturing date on this product. Buying this product from a slow selling dealer in Canada, can lead to very expensive repair bill and no one seems to want to protect the consumer. I blame the API for not forcing the manufacturing date to be labelled on the box instead od a code that most people can't read because each manufacturer is different.
