Aaron Posted September 24, 2010 Share Posted September 24, 2010 I know its still a little early in the game for numbers yet, but I had a customer in the other day who is a 6.7 owner, and he was concerned with the effect this campaign has on fuel economy/urea usage, if any at all. Any real-world reports from anyone yet guys? I think his primary concern is the fact that he is averaging around 700 km a tank, and likely would like for it to stay there, or improve. Thanks in advance guys! Quote Link to comment Share on other sites More sharing options...
dpurvis Posted September 24, 2010 Share Posted September 24, 2010 have heard of customers saying they lost mileage, but ford actually claimed better milage. they say original calibration was 18% better than 6.4 was and the new calibration was 20% more. guess time will tell. but i do know most customers tend to say that always. they also always claim power is down, but i guess they won't with this one.

Keith Browning Posted September 24, 2010 Share Posted September 24, 2010 I just want to know how they can INCREASE power and at the same time INCREASE fuel efficiency. Quote Link to comment Share on other sites More sharing options...
Jeff_E Posted September 24, 2010 Share Posted September 24, 2010 The explanation I heard is that the torque increase resulting from the extra fuel they inject allows them to change the transmission shift schedule such that there is a net increase in fuel economy. I think it was our FSE that told me that but I don't remember for sure. Quote Link to comment Share on other sites More sharing options...
Bruce Amacker Posted September 24, 2010 Share Posted September 24, 2010 I just want to know how they can INCREASE power and at the same time INCREASE fuel efficiency. Advance the timing (which also increases NOx emissions). Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted September 24, 2010 Share Posted September 24, 2010 Therefore we might expect to see higher DEF usage? Quote Link to comment Share on other sites More sharing options...
Bruce Amacker Posted September 25, 2010 Share Posted September 25, 2010 In my opinion that might be true, but it might also depend on how the driver uses the HP. Perhaps Cetane would care to comment. Quote Link to comment Share on other sites More sharing options...

I know I would being driving it hard to see if there was a difference. Maybe thats why there is a drop in fuel economy, people like the power. check this ssm out 21476 2011 F-SUPER DUTY EQUIPPED WITH LT275/65R 20E A/T OWL MICHELIN TIRES - ACCELERATED TIRE WEAR SOME 2011 F-SUPER DUTY VEHICLES EQUIPPED WITH LT275/65R 20E A/T OWL MICHELIN TIRES MAY EXHIBIT ACCELERATED TIRE WEAR AT LOW TIRE MILEAGE (UNDER 10,000 MILES/16,090 KM).
