F250 PSD vs F150 5.0L towing 9k lbs
The F250 got 9 mpg towing a 9k horse trailer. I wonder how folks here tow a 35' high profile 5er and get 12 mpg out of their diesels? :W VIDEO The 5.0L got 8.4 mpg towing the same trailer.

I would suspect the diesel had a regen too. I would expect considerably better mileage towing that trailer with a diesel because my Ram is very consistent at 10.5-11 mpg towing my high profile 16k lb fiver (hand calculated).
When the particulate filters first came out it seemed that for every diesel truck test they made a big deal out of doing a regen before the test. I don't think that I have seen that mentioned lately. Of course, a true test should last an entire cycle of the filter getting dirty and then getting a regen. Or at least a fudge factor for the inevitable regens if you know that one was not done during the test.
