Re: Whats the deal with the Diesel fluid ?

Yea, I know it is the same, (nearly) as the 6.4, but I remember reading someplace that the 6.4 used all eight cylinders at once, where the 6.7 used one bank. Half the injectors for each regen, PLUS it does it less....because of the DEF....
That's why the 6.7 get's so much better mileage in stock trim.
I guess I didn't realize that the DEF was that large of an impact, I just figured it was primarily because of only 4 cylinders being used. (They can use 4 vs 8 ALSO,,,,because of the DEF I guess....) Hey, you can learn an old dog new tricks,,,,

*48* Jim T. 2011 F-350 Lariat, CC, LB, SRW. White Platinum Metallic Tricoat. Black leather seats, I probably wont have*PMS,, with this one, at least no major attacks of it!
