OK how did you get that kind of mileage? I'm only getting 13 highway with my 2015 6.7 CCLB SRW, 10 towing a 35ft 5W.

I just recently purchased a 2011 F-350 6.7 with 42,000 on her. I knew the original owner who purchased the truck to pull a 5th wheel from Michigan to Florida and that's all it did. He died and the truck became available so I purchased it to also pull a 5th wheel from Michigan to Texas and we are getting ready to embark on our first adventure on Jan 10th. So I didn't have the truck a month and the check engine light came on so I watched it for a day or two and then it went off. No problem right? Well a week later it came on again and then off again and so on and so on. I took the truck to a ford dealer to have them scan the computer and tell me what the problem was, They said that the EGR cooler was plugged and needed to be replaced. Cost $1300.00 and the def tank was also showing alarms in the history suggesting it was beginning to fail with a repair cost of $900.00 I was also told that these trucks will computer disable the truck if the engine light is not addressed within so many miles and I didn't like that. So I looked into a total Def delete with 5 tunes for a cost of $2000.00 and decided to go that route. Mileage has steadily gone up since the delete to about 22Hwy empty and no check engine lights since. As I said getting ready to tow 16,000 down to Texas in another week, I will keep you posted on our success or failure. Additionally, someone else said that these diesels need to be run and I believe he is right, you have to get them up to temperature and breathing like a race horse.

That's right. Get them to temp and they will purr like a kitten. I'm at 22 empty also, 14 pulling my 9000lb TT through the Carolinas, TN, and GA. I never exceed 65mph. Runs perfect. Zero issues. Runs cool and breathes easy. Ford Master Powerstroke Certified Mechanic deleted DEF and EGR with light tow tune.
