Design intent for GM was to have the need for a DEF refill at the time of an engine oil change. For most of us "road warriors" that rule of thumb should apply. (This is utilizing the on-board oil life monitor as the oil change interval indicator). If you use an arbitrary number, such as 3000 miles as an oil change interval, you could only fill DEF every other oil change.
Some work applications could change this scenario...such as snow plowing, PTO use, high idle times, etc.

We have a 2011 Silverado 3500 Duramax which uses the DEF. We now have 16,000 miles on the truck, and have added DEF sevral times We are using a 2.5 gallon bottle of Peak DEF every 2,500 miles. We buy the DEF at Wal-Mart for $11.50. This make the DEF cost factor negligible. I'm sure that the Ford diesel would be about the same in this area.

I have seriously looked into replacing my 02 gmc oil burner (with either a ford or gm) since reaching 200k miles but have a question for those of you that have 2011or 2012 models that have the regen to burn off the soot. Do your fuel milage computers account for the fuel burn during the regen? Has anyone done enough fuel receipt collection over an extended period of travel to verify the computer. It is great that some people are reporting such great milage figures but it seems to conflict with other reports on the diesel forums that I have visited.
Not to be disrespectful so I am posting this same question on the Duramax thread, too.

If a truck rusts fast why buy a diesel engine that will far outlast the truck? Which ever way you go I would defiantly rust treat your new truck no matter what the dealer says.

It followed me home!
I test drove a new 2012 F250 Super Duty Crew Cab Lariat Diesel and it followed me home. The difference between my 2007 and the new 2012 is incredible. It is hard to tell the new diesel is not a gas engine from the sound it makes when it is running. The difference between the 2007 and the 2012 is really noticed when the accelerator is pressed and it takes off like a rocket. With all the technology and features, I think I may need to go to school to learn how to use them.

We have a 2011 Chevrolet Silverado 3500 Duramax. We took delivery on August 5, 2011. It was one of the last 2011's made. It now has 16,000 miles on it. I have closely monitored fuel consumption from the beginning, both manually and with the on-board computer. I have found the on-board computer to be extremely accurate. I now depend on it solely.
Thus far, the fuel mileage has been roughly what I expected. The truck alone has gotten 18 mpg on the highway. Pulling the Airstream with the solo truck gets 13 mpg. With the Outfitter truck camper solo, it gets 14 mpg. Pulling the Airstream with the Outfitter on board, the truck gets 11 mpg.
The truck has been consuming approximately 2.5 gallons of DEF every 2,500 miles.
I had the truck at a Chevrolet in Scranton, Pennsylvania, for a DEF system warning message. It turns out that I had turned the truck off during a regen which resulted in this warning the next morning. I did find out from the technician that the truck had under gone 10 regens with 10,000 miles on it. This would indicate that a regen takes place roughly every 500 miles with my type of driving. WE do mostly highway driving. Our average speed at 15,000 miles was 45.6 mph.

In 10,000 miles I've used 5 gallons of DEF, the Motorcraft DEF I purchase comes with a nice filler attachment - 12.00 bucks a bottle.
I tow a 2011 30 foot Airstream via mountains, etc. and cruise around at 75-80 when not towing - 70 average when towing.
$24.00 per 10,000 miles with exhaust cleaner than a gas vehicle and way better mileage multiplied by much more torque to boot - same setup as on my Touareg (and new Cayeene when released in oil burner or Grand Cherooke in oil burner), DEF is the future of all Oil Burners and why I'm a fan of the new TDI engines over gas engines!

Sorry for the late reply. I've been off the forum for some time. I'm not sure which ratio we have. We didn't have a choice, since the truck, in all it's other features was on the lot. But, it is either 3.31 or 3.55. I didn't think it would make a huge difference, but that is my ignorance talking.
We had such a great time on our trip and learned what we liked and didn't like about our Safari, that when we found a 28' International, we traded up. The Mary Joan II is now in Savannah, GA awaiting our trip to Florida in February.
Happy New Year

Sorry the late reply,
But, my experience has been similar to other replies to your question. It does vary greatly depending on how much load you place on the engine. And, in my experience, increased idling time really uses the stuff up. Overall, it is not a major expense.
One interesting observation, mosquitoes find the exhaust gas very appealing. We were at a state park in Pennsylvania early on in our trip and I had to put a long sleeve jacket, pants and insect head screen to unhook the TV.
Happy New Year

FYI, no modern diesels need to idle. This practice is a carryover from antiquated technology. Please, to save the air and oil, and money, operate your modern diesels just like a gasser. No need to warm up. no need to keep running in cold weather....they'll restart fine.
Manufacturers from small 4 cyls to class 8 trucks are starting to put idle time limiters on their vehicles to stop this practice. It is completely unnecessary.

I agree 100% about idling modern diesels. But, I do let the diesel 'warm up and cool down a little more than I do my much smaller gasoline engines. I am particularly careful to avoid situations where I don't run it long enough to bring the engine up to full operating temp and maintain it for at least half an hour if I am going to shut it down and let it sit for a few days.
This is probably a hold over from my time owning sailboats with diesel auxiliary engines. I was taught that running the engine just long enough to get into or out of the slip was very hard on the diesel since the moisture generated never gets completely boiled off and remains in the oil. Analyzing the oil for water and other contaminents is common in the marine industry.
Only five more weeks until we head south, hooray
Take care
Wayne

I would even say that's no longer necessary. The warm up and cool down periods were primarily to ensure oil to turbo bearings at startup and to cool down the extremely hot turbo bearings so no cooking and coking of the oil occurs. Both resulting in premature turbo failures. Most if not all (check your own) of the turbo center sections are now water cooled and never see those extreme temperatures. Also, modern oils are both, much better cold flowing and heat resistant, especially the synthetic diesel formulations.

dznf0g, I agree. In fact there's probably way to much idling going on with these modern diesels. The Ford Diesel Supplement manual the truck comes with warns against long idling for warm up (it won't in cold weather). BUT, it does have one exception. The diesel supplement does state that after extended high speed, high ambient temperature or high GVW/GCW tow/haul operation you should let the truck idle for 3-5 minutes to let the turbocharger and engine return to normal operating temps before shutting down.

I would definitely agree if your going from 60mph to 0mph and shutting it off right away. But MOST of us, MOST of the time have a period of time where we are low speed driving, easy throttle, stop lights, etc. to get to our destination. That is plenty of time to cool all the real hot stuff. Just use common sense.

I have a diesel truck and I agree, mostly, with what I have been reading. Generally when driving I find that there is enough low speed operation prior to shutdown to allow the engine/ turbo/ trans to come to operating temps. So under these conditions allowing it to idle in unnecessary and simply a waste of fuel. I will offer my suggestion here that when operating at highway speed and you pull off into a rest area for a pit stop there has not been that extended low speed operation and here ( and here only) I would let it idle for perhaps only an extra couple of minutes to give some time to cool down.

OK, I have an '06 F250, you guys have me very tempted in looking at a new model.
