I don't have a diesel but why not top it off at every oil change? If you do with your tested 15,000 mile range you should never have to worry about running low.
theyve had too many marijuanasTalking to one of the techs at the dealership when I had the oil changed last on our diesel (the first one we had to pay for - still cheaper than me doing it) - they've actually found that adding it when it doesn't really need it (i.e. every oil change) seems to cause issues. They only like to add it when it's actually lower.
I add when it gets to 35%, sometimes sooner. never had an issue in 146K miles.Talking to one of the techs at the dealership when I had the oil changed last on our diesel (the first one we had to pay for - still cheaper than me doing it) - they've actually found that adding it when it doesn't really need it (i.e. every oil change) seems to cause issues.

Being new to the DEF thing, how long (generally??) is it lasting per tankful of DEF?? I am hearing some guys say 8,000 miles, @LiveTrash above got 15K out of a tank. Also, how long between oil changes are you guys getting before the DIC is saying take her in for an oil change?? My Toyota goes 10 K between oil changes on synthetic and so do the AMGs.I add when it gets to 35%, sometimes sooner. never had an issue in 146K miles.

that sounds about right, I`ve only topped up mine 3 times in 55,000 kmsJust got a message on a brief run I did this morning in the car. About halfway through the run I got the DIC message pop up saying "Diesel Exhaust Fluid Range: 1518 km". I flipped the screens over to the percentage remaining indicator and it read 9%. If it's accurate, it seems my factory filled tank of DEF will last me about 24,500 kilometers (15,223.59 miles). I do about half city and half highway driving. The dealership gave me a small bottle of the stuff to fill up when I need which doesn't seem to be enough to fill even half the tank. I'll go how ever long I can on that and then buy a larger jug of it from my local truck store.
Has anyone else run close to empty on their DEF or do you usually keep it topped up every oil change?
I never really measured my DEF consumption, but it doesn't seem all that often. My DIC seems to be hard coded to 7500 miles. I have been resetting it once and going through 2 (15K miles) per oil change. but for me, that's like every 3 months. There's an oil analysis thread on here where I posted my results. 15K seems to be a happy medium for oil life, given my driving habits.Being new to the DEF thing, how long (generally??) is it lasting per tankful of DEF??

If I remember correctly I went about 13k miles on the factory DEF fill before it was low enough for my comfort. Now whenever it says a percentage left I'll dump a 2.5gal container of DEF in.Just got a message on a brief run I did this morning in the car.
