That's a good DEF strategy. I might do the same. I also avoid additives for the same reason. If the Chrysler doesn't require it then I'm not going to add it.I figure that I use less than a gallon of DEF a month. So the most I could save is about five bucks a month.... Why bother.
I am more concerned with the age of the DEF in the tank. Unfortunately I recently got a "Will not start in 200 mile warning" and when the service dept cleared it they topped of the tank with fresh DEF. (at no charge). My vehicle was waiting for a new cat which has since been replaced. But I stopped getting CEL's after the fresh DEF was added. I'm thinking that the marginal cat with old DEF might be why the problem started after 8k or so miles. My game plan now is to wait about 2500 miles and add one gallon of fresh.... then repeat until I'm down to 1/4 tank. That way I should be able to keep the DEF in the tank reasonably fresh.
I use high volume pumps for my Diesel..... I had also considered adding a fuel additive..... but decided against because that might raise questions if I have engine problems.
The service department has to meet conditions set by Chrysler or they won't get paid....... I want to make their life as easy as possible. It just makes sense.
I love my vehicle... a 4x2 limited with Bridgstone Blizzak snow tires (I think cooper makes some that are just as good). I got them from Costco so they will change them back for twenty bucks in the spring. The tires and 2 two sixty pound tubes of sand in the back with a short handled shovel have been handling these back to back storms we have been getting. There are a couple of hills around that are steep enough so that they just need be avoided. with hard packed snow/ice going up my 2wd can handle it. Going down not so hot.... more like a sled ride, The towns between my home and the mall I work at seem to be under the impression that if God Put it there Got will take it away. No sand or salt and barely plowed.
The whether tech mats are worth there weight in gold. and I am considering adding a winch and lights to the front.
I am patiently waiting for global warming........... I was promised it and I want it,
Thanks for the update. Just wondering if your vehicle is a 2014 or a different year? The Jeep factory and several dealers in the area told me the 2014's did NOT come with a filler cap on the DEF filler port. Thanks for the info.Don't know where the dealer gets his info. My DEF tank came with a cap and has one currently. It's the DIESEL filler neck which is not capped and always open.
My 2014 has a DEF cap. You can't let contaminants in there, so there's gotta be a cap.Thanks for the update. Just wondering if your vehicle is a 2014 or a different year?

i have a 2014. The DEF does have a cap. Diesel fuel input does not. Fortunately I have not had ANY problems with my GC. 25K milesThanks for the update.
