    My truck's DEF gauge randomly after startup will show full. Driving 30+ miles it will slowly go back down 1/4 which is what I believe is the current amount in the tank. Truck has 5,700 miles and has not been refilled yet on DEF. This issue started after my DEF tank got below 1/2. Any ideas?

    We have a 6.7 at work that rarely needed any DEF, then it went in for a recall. Not it consumes much more. How much do your trucks go through? Thanks!

    I'll try not to get too long winded but if anyone knows a shop that can help I would appreciate the info. Friday night I left Albuquerque on my way to IN to pickup a trailer. Just after getting to Tucumcari the rains started. It was torrential. About 20 miles east of entering the rain the CEL...

    I have a 2014 6.7 that gives me the message "cleaning exhaust filter" just about every time I drive it. Then the other day I got the warning that my DEF fluid was getting low, but the next time I drove my truck there was no warning, and I haven't seen it again since. My truck has 25000km on it...

    I incidentally put 0.02 gallons of DEF in my diesel tank while the truck was running. I then drove 300 miles, never shutting the truck off. It drove fine. The next morning I started it up, no problem, then the LOW FUEL PRESSURE light came on. It continued to run fine. I'm getting the fuel...

    Has anybody tried the SuperS DEF fluid? A local chain of "convienence stores" in South Texas (Bucees! it is actually an awesome place) carries the SuperS brand at a VERY reasonable cost. By the label it meets all the specs. I just thought I might see if anyone has actually used it.

    OK, so I've got a 2011 F350 (SRW) 4WD longbed that I use to tow either a 20' rollback car trailer, a 26' enclosed car hauler or a 35' gooseneck 2 car wedge hauler. 60% of my usage is towing, 40% just daily driving. I'm currently at 70k miles and don't want to do anything that will void the Ford...

    How far are you guys going on a tank of DEF? I read that we should get 5000 +/- per tank. I have 6500 miles on my 13, it was full when I bought it, I have added 5 gal since and it tells me 500 miles to empty. If 5000 miles per tank is true, I am hemorrhaging fluid.
