(addendum to prior "Abusive streak" thread, in the prior thread I drove the 1600+ miles to work, cruised 75-80+ mph up hills on cruise control
). Coming home I pulled the 8,000 trailer, it was a 1719 mile trip, so I topped off the DEF tank to check consumption. I cruised home averaging 66.5 mph moving per Garmin. Halfway home, lost power, no 'warning lights, no warning messages', no overheating, truck ran okay, just no power to pass, no acceleration up hills, transmission did not shift correctly. Did not worry, as temps, basic functions were okay. Reminded me of a big block chevy with a restricted fuel filter, high rev's, no power. This morning, went to the dealer, had the fuel filters changed. Immediate
benefit, this truck NEVER
had this much power.
Took traction control off, locked the rear end, nailed it. It went sideways, straightened it out and left two rubber streaks for the salesmen to sell 2011's
(I drove my 6.0 like this, about 25% the distance or less, stretched headbolts. This
truck was driven both ways, cruising 70 +, top speed per Gramin 84+ mph, up grades, over hills, 6400 elevation at times, no problems other than maintanance related fuel filters. No comparison to the stock 6.4, or the modded 6.0).
DEF?? Topped off the DEF tank, took less than 1 gallon for 1719 miles running hard.
Lose power? Not to worry, recommend having the dealer change BOTH filters, or check spec's on which one to change first....
