MPG surprise for a 6.0

Got quite a surprise yesterday from a truck I have owned since new.Its the 06 Lariat SRW 4" lift with 35 tires and 265,000km.Now all the times I drove this truck south empty before the motor was replaced with a stock 04 6.0 with 80,000 km I would only get about 12-16mpg.Loaded pulling my 5th wheel with upto 18,000kg+ or - depending on the trip the truck always ran around 8-10 mpg. Well this week I took the truck for a tour of Alberta (empty)from the great white north here and put on easiely 3600 km.What amazed me was the the truck ran a steady 18 - 20 mpg the whole time with a average speed of 105-110 km 60 - 70 mph.I did the motor swap at about 218,000 km did the egr delete coolant flush and change oil cooler and a coolant filter.I hardly pull with this truck anymore and mainly use it in the winter for hotshots or piloting and did notice that the mpg went up a notch or 2 put this has impressed me for the mpg.Just for info the motor was a 04 and thats all I used from the donor all sensors and electrical was the 06 stuff. Deltas were ECT 193-195 EOT 196 - 199 (scangauge)the entire trip over 5 days.Hopefully when I do the 06 dually (aprox350,000 km) with the 07 motor I got it works the same. Love my 6.0

I always get better mileage when I go through Canada.

They dont put all of the additives (garbage)in thier fuel like we do in the here in the States.

Energetically will I meet the enemies of my country. I shall defeat them on the field of battle for I am better trained and will fight with all my might. Surrender is not a Ranger word. I will never leave a fallen comrade to fall into the hands of the enemy and under no circumstances will I ever embarrass my country.

Semper Fidelis (Always Faithful) is the motto of the Corps. That Marines have lived up to this motto is proved by the fact that there has never been a mutiny among U.S. Marines.
